Loose aggregates are the unsung heroes of every building and landscaping job — cheap, simple and endlessly useful. Picking the right one saves time, improves results and keeps projects on budget. Below we are six of the most common loose aggregates you’ll see on site — Building Sand, Sharp Sand, Ballast, Soft Washed Sand, MOT (Type 1) and Pea Shingle — what each one does best, and the UK industry trends you should know about right now.

Building sand

A fine, soft sand with small, smooth grains. It mixes easily with cement to make mortar that’s workable and forgiving for laying bricks, pointing and plaster repairs. Because it contains finer particles and a little natural clay, it grips well and gives a smoother finish than coarser sands.

Advantages and typical uses: ideal for bricklaying, internal plaster repairs and softer finishing mortars where ease of use and a neat finish matter. It’s not the best choice where you need grit and drainage — it will retain more water than sharper sands.

Sharp sand

Sharp sand (also called grit sand) has larger, angular grains and a gritty texture. It’s available washed or dry-screened; washed sharp sand has had silt and dust removed and is better for concrete or paving work.

Advantages and typical uses: excellent for concrete mixes, bedding paving slabs and where drainage and mechanical strength are required. Because of its coarser texture it makes stronger, more durable mixes than building sand.

Ballast

A blended coarse aggregate, typically a mix of gravel (or crushed stone) and sharp sand. It’s supplied in sizes such as 10mm, 20mm and blended grades that are ready to mix with cement to make concrete.

Advantages and typical uses: the go-to for general concrete — footings, slabs, shed bases and steps. Ballast saves time because it’s a pre-blended aggregate suitable for robust structural concrete and large-volume pours.

Soft washed sand

Soft washed sand is a finely graded sand (commonly 0–2mm) that has been cleaned to remove dust and impurities. It’s specifically produced for mortar, rendering and plastering where a consistent, smooth finish and predictable mixing behavior are required.

Advantages and typical uses: perfect for making mortar to lay bricks and blocks, for rendering and internal plaster where a fine texture and good binder adhesion matter. Washed sands reduce the risk of contaminants affecting cement set and strength.

MOT (Type 1)

MOT Type 1 is a crushed, well-graded aggregate, typically a mix of sizes down to fines. It compacts to form a strong, load-bearing layer.

Advantages and typical uses: used as a structural sub-base for roads, driveways, hard-standings and foundation sub-bases where compaction and bearing strength are essential.

Pea shingle (pea gravel)

A small, rounded gravel (usually 4–8mm) often used for decorative finishes and drainage. Its smooth, rounded stones give a tidy, low-maintenance surface appearance.

Advantages and typical uses: great for decorative driveways, pathways, borders, weed suppression, and drainage layers around drainage pipes or in reed beds. It’s also widely used as a mulch in planting beds where appearance and water retention control are important.

Current UK trends you should know about

The aggregates industry in the UK is rapidly embracing sustainability. Recycled and secondary aggregates now make up a growing share of the market, as contractors look to reduce environmental impact while meeting performance specifications. You’ll also find a surge in demand for decorative aggregates — pea shingle and coloured gravels are especially popular for landscaping and driveway projects. Investment in recycling facilities is making high-quality recycled MOT Type 1 and sub-bases easier to source, helping builders and landscapers balance cost, performance, and environmental responsibility.

Final thought

Loose aggregates might look simple, but choosing the right one makes all the difference in durability, appearance, and cost-effectiveness. Whether you’re laying a driveway, building a patio, or mixing mortar for a wall, understanding your options ensures a better result.

If you’re a landscaper, builder, or retailer looking for a decking solution that’s low-maintenance, long-lasting, and easy to install—composite decking is the way to go. At Chandler Materials, we supply both Millboard and NewTechWood, two of the most popular brands in the market, each offering a stylish and durable finish with straightforward installation processes.

Let’s break it down with a quick guide on how to lay each, and what makes them slightly different from one another.

What is Composite Decking?

Composite decking is made from a blend of materials (usually recycled wood fibres and plastics), making it more resistant to weathering, warping, or rot than traditional timber decking. It also looks great—available in a range of natural tones and textures.

Quick Guide to Laying Composite Decking

Here’s a simplified step-by-step to get your deck laid fast:

1. Plan Your Deck Area
   Measure out your space and mark where your joists will go. Good airflow underneath is essential.
2. Prepare Your Base
   Use a solid, level subframe. Either timber or composite joists work, depending on the product spec.
3. Fix Your Joists in Place
   Joists should be spaced according to the brand’s requirements—Millboard and NewTechWood vary slightly here (see below).
4. Lay the Deck Boards
   Start from one side and use the correct fixings. Boards are typically fixed using hidden clips or stainless screws (no visible screws = sleek finish).
5. Leave Expansion Gaps
   Always allow for a small gap between boards to handle expansion and drainage.
6. Add Edging and Finishing Touches
   Use edging trims or fascia boards for a tidy, professional finish.

Millboard vs. NewTechWood – What’s Different?

Millboard is hand-moulded from real oak and features a unique polyurethane resin core. It’s fixed directly through the board using Durafix® screws, which leave virtually no visible marks—no clips needed. Joist spacing is typically 400mm centres. Click here to see how simple installing with Millboard really is!

NewTechWood uses a fully capped composite system and is installed using a hidden clip system. The clip design allows for a consistent gap between boards and quick, even installation. Joist centres should be 300–350mm depending on the direction of the board. Click here to watch a video on NewTechWood’s easy installation set-up.

Both are easy to work with, require no staining or sealing, and are backed by strong manufacturer warranties.

Laying porcelain paving in your garden is one of the most effective ways to create a clean, modern outdoor space that’s built to last. Known for its durability, low maintenance, and sleek appearance, porcelain has become a go-to choice for homeowners and landscapers across Essex. If you’re planning a garden transformation, this step-by-step guide will help you get it right first time.

Why Choose Porcelain Paving?
Porcelain paving slabs offer a range of benefits that make them ideal for outdoor use. They are non-porous, meaning they resist stains, algae, and moss growth far better than traditional natural stone. Their consistent sizing and finish also make them easier to lay with a crisp, contemporary look. Plus, they’re incredibly hard-wearing and colourfast, so your patio will look great for years to come.

Tools & Materials You’ll Need
Before you begin, make sure you have everything ready. This includes your porcelain slabs, a suitable sub-base material such as MOT Type 1, sharp sand or a mortar mix, a priming slurry, spirit level, rubber mallet, tile spacers, and a cutting tool suitable for porcelain.

Step 1: Prepare the Ground
A solid foundation is crucial for any successful paving project. Start by excavating the area to a depth of around 150–200mm. Ensure the ground is level and compacted before laying your sub-base.

Add your MOT Type 1 sub-base in layers, compacting thoroughly as you go. This will prevent movement and ensure long-term stability. Aim for a finished sub-base depth of around 100mm.

Step 2: Create a Full Mortar Bed
Unlike some traditional paving methods, porcelain paving must be laid on a full mortar bed. This provides full support and prevents cracking.

Mix a strong mortar (typically 4:1 sharp sand to cement) and spread evenly to a thickness of around 30–40mm. Avoid spot bedding at all costs, as this can lead to weak points and future failures.

Step 3: Apply Priming Slurry
This is one of the most important steps when laying porcelain paving. Because porcelain is non-porous, it won’t naturally bond with mortar.

Apply a priming slurry to the back of each slab just before laying it. This ensures a strong bond between the slab and the mortar bed, preventing lifting or movement over time.

Step 4: Lay the Slabs
Carefully place each slab onto the mortar bed, using spacers to maintain consistent joints (typically 3–5mm). Use a spirit level to ensure each slab is level and gently tap into place with a rubber mallet.
Work methodically, checking levels regularly and maintaining a slight fall away from your property to allow for water drainage.

Step 5: Jointing
Once the slabs have set (usually after 24 hours), it’s time to joint. Use a suitable porcelain jointing compound or grout, ensuring it is designed for narrow joints and external use.
Brush the compound into the joints and follow the manufacturer’s instructions for finishing and curing.

Key Tips for Success
– Take your time with preparation. A strong sub-base and full mortar bed are essential for long-lasting results.
– Always use a priming slurry. Skipping this step is one of the most common mistakes.
– Check levels constantly to avoid uneven slabs and water pooling.
– Plan your layout in advance to minimise cuts and achieve the best visual finish.
– Use the right tools, especially when cutting porcelain, as it is much harder than natural stone.

Common Mistakes to Avoid
One of the biggest issues with porcelain paving is poor adhesion, usually caused by missing the priming slurry step. Another common mistake is spot bedding, which leads to unstable slabs. Rushing the groundwork or failing to allow proper drainage can also result in costly problems down the line.

If you’re planning a new patio, driveway, or garden path, choosing between porcelain paving and sandstone paving can feel overwhelming. Both are popular choices, but they each offer unique advantages depending on your style, budget, and intended use.

Here’s a clear, practical guide to the key differences between porcelain and sandstone paving and how to lay each type correctly to achieve a durable, attractive finish in your garden.

What Is Porcelain Paving?

Porcelain paving slabs are manufactured from refined clay, fired at high temperatures to create a hardwearing, low-porosity slab that is resistant to staining, algae growth, and fading. They come in a wide range of colours and finishes, from contemporary grey tones to stone and wood effects.

Key benefits:

• Low maintenance and easy to clean
• Highly resistant to frost, moss, and algae
• Consistent colours and finishes
• Non-porous surface reduces water absorption

What Is Sandstone Paving?

Sandstone paving is a natural stone product formed over thousands of years, offering unique colour variations, veining, and a more traditional appearance. It is porous, allowing water to seep through, and will weather naturally over time, adding character to your outdoor space.

Key benefits:

• Natural beauty with unique patterns and colours
• Provides a traditional or rustic aesthetic
• Can be sealed to help reduce staining
• Offers good slip resistance when wet

The Visual Differences

• Porcelain paving often looks more uniform, with modern styles suited to contemporary gardens and outdoor living areas.
• Sandstone paving offers warm, earthy tones that blend seamlessly into natural surroundings, making it ideal for cottage gardens and traditional properties.

How to Lay Porcelain Paving

Porcelain paving requires correct installation for durability and safety, as its low porosity means it needs a solid, stable base and appropriate priming to bond.

1. Prepare the base
   Excavate to the required depth (usually 150-200mm depending on ground conditions) and lay a compacted sub-base of MOT Type 1 or similar.
2. Apply a full mortar bed
   Porcelain slabs should always be laid on a full mortar bed (5:1 sharp sand to cement mix) around 30-40mm thick to prevent movement and cracking.
3. Use a slurry primer
   Back-butter each slab with a porcelain primer slurry to improve adhesion to the mortar bed.
4. Lay the slabs with a slight fall
   Ensure a fall of around 1:80 away from buildings for drainage.
5. Jointing
   Use a suitable outdoor grout or jointing compound, ensuring joints are fully filled to prevent water ingress.

How to Lay Sandstone Paving

Sandstone paving can be laid using both full bed and spot-bedding methods, although a full mortar bed is recommended for stability and to prevent slabs from rocking.

1. Prepare the sub-base
   Dig down to a suitable depth and lay a compacted MOT Type 1 base layer.
2. Full mortar bed
   Lay the sandstone slabs on a full mortar bed, using a 5:1 sharp sand and cement mix.
3. Positioning and levelling
   Tap down with a rubber mallet to level each slab while maintaining a consistent joint gap (typically 10-15mm for sandstone).
4. Jointing
   Once the paving has set, joints can be filled with a traditional sand and cement mortar mix or a ready-made jointing compound.
5. Sealing (optional)
   Sealing can enhance colours and help prevent stains but is optional depending on the finish you desire.

Which Paving Should You Choose?

• Choose porcelain paving if you want a low-maintenance, modern look, with high stain resistance and consistent colours.
• Choose sandstone paving if you prefer a natural, traditional appearance with variation in tones and textures.

Both paving options can transform your outdoor space beautifully when installed correctly, providing a long-lasting, functional, and attractive area for relaxing or entertaining.

At Chandler Materials, we’re proud to announce a pledge of £20,000 worth of building materials to CHESS Homeless for their innovative “Turning Point” development in Stock. This pioneering project will see the transformation of an old motel site into 24 modular, self-contained homes, providing essential, independent living spaces for single adults experiencing homelessness. Supporting projects that give back to the community is a core value for us as a family-run business, and we are honoured to contribute building supplies to such an important cause.

Turning Point: A New Vision for Independent Housing

With the Turning Point project, CHESS Homeless is taking an inspired approach to addressing homelessness in our region. By replacing the nine existing units at the Stock site with 24 modular homes, CHESS is creating private, self-contained spaces where residents can address personal challenges and build essential life skills in a stable environment. On-site support staff will be available to guide individuals through these vital transitions, ensuring they receive the help needed to overcome the root causes of their homelessness.

Our donation of materials will aid in the construction of these modular units, which can be completed quickly—within as little as 10 days—ensuring that new residents can move in sooner. Furthermore, these homes are adaptable for people with disabilities, offering a truly inclusive housing solution that fosters independence and dignity.

Building with Purpose: Accelerating Change with Local Partners

The modular housing project is set to meet a strict timeline due to funding from the “Single Homeless Accommodation Programme” (SHAP), a collaboration between the Department of Levelling Up, Housing and Communities (DLUHC) and Homes England. Choosing modular construction allows CHESS to proceed with building the units alongside groundwork preparation, streamlining the process to ensure the project is operational by March 2025. Local partner Morgan Sindall Infrastructure has also generously offered to assist with site preparation, including concrete removal, laying foundations, and establishing wastewater management for the site. This collaboration exemplifies the power of local partnerships in achieving impactful, community-driven goals.

Investing in Long-Term Community Support

Beyond housing, CHESS Homeless has a proven record of making a substantial social and economic impact, delivering £5.6 million in value from £1.4 million in operating costs over the past year alone. With the completion of Turning Point, this value will only increase, not only benefiting those they support but also strengthening the community as a whole.

Our pledge of building materials reflects Chandler Materials’ wider commitment to giving back. As a local, family-run business, we are proud to stand behind initiatives that provide lasting benefits for our communities, and we look forward to continuing our support of CHESS Homeless and other local charities. Working together, we believe we can make a meaningful difference in the lives of those who need it most.

Transform Your Garden with Fencing & Trellis – When & How to Do It Right

Whether you’re creating privacy, securing your boundary, or adding structure and charm to your outdoor space, installing fencing and trellis is one of the most effective ways to upgrade your garden. At Chandler Materials, we supply high-quality fencing products from trusted names like Grange Fencing, helping both trade professionals and homeowners get the job done properly.

When’s the Best Time to Install Fencing or Trellis?

The ideal time of year to install fencing is during the late winter to early spring months (February–April). The ground is soft enough for digging post holes, yet not so dry and hard as in high summer. Plus, installing before the main growing season allows any plants or climbers to quickly establish along your new trellis.

That said, autumn is also a great time – especially for replacing damaged panels before winter weather sets in. Just avoid installation during extreme frost, heavy rain, or heatwaves, which can cause the ground to shift or dry too fast.

Installing Fence Posts the Right Way

Getting your fence posts right is crucial to a secure, long-lasting fence. Posts should be set at least 600mm deep into the ground (or one-third of the total post length), using post mix or concrete to fix them firmly. Use a spirit level to ensure they’re perfectly upright, and allow the mix to set fully before attaching panels or trellis. For added durability, consider using concrete posts or applying a protective post saver sleeve around the timber. Spacing your posts evenly – typically 1.8m apart for standard panels – will help keep everything stable and tidy.

Year-Round Fencing Maintenance Tips

Fencing, like any outdoor investment, needs a little care to stay looking good and performing well:

Spring & Summer: Check for signs of wear and tear – especially after heavy rain or strong winds. Clean off algae or mildew with a stiff brush and a mild cleaner.

Autumn: Clear away leaves and debris around the base of posts to avoid rot. Make any repairs now before the harsher weather arrives.

Winter: Inspect panels for movement or leaning caused by high winds or saturated ground. Ensure trellis fixings are still secure, especially if supporting heavy climbers.

Applying a timber preservative or treatment annually can dramatically extend your fence’s lifespan – even for pressure-treated timber.

As we mark International Women’s Day on 8th March, we wanted to take the opportunity to celebrate some of the talented women across Chandler Materials who help drive our business forward every day.

The construction and building materials industry has traditionally been male-dominated, but this continues to evolve as more women build successful careers across the sector. From marketing and finance to HR and leadership roles, women are making an important impact across the industry.

To recognise this, we spoke with three members of our team – Lauren Penney, Katie Choppen and Sara Day – about their experiences working within the construction and builders merchant industry.

Lauren Penney – Marketing & Operations Manager

1. What inspired you to pursue a career in the construction or builders merchant industry?
   I was inspired to join the building materials industry because my mum was in the industry. She set such a good example of how a woman can be successful in our industry & still have a family.
2. How has working in this industry helped you grow personally or professionally?
   Working in this industry has really helped me. I’ve grown in confidence & my sense of self-worth is much higher than previously. I credit this to the numerous networking opportunities in our industry to meet genuine, and real people who all want to work together for the industry as a whole.
3. Have you seen the industry become more inclusive over time?
   The industry is definitely more inclusive, even only over the 10 years I’ve been in the industry. When I first started out there would be only a handful of women or minorities at industry events. And although it is not a 50/50 split, there are definitely more women in the room & taking on more senior roles in our industry.

Katie Choppen – Finance Manager

What has your experience been like working in a traditionally male-dominated environment?
Overall my experience has been good. I have been treated as an equal, been made to feel like my opinion matters and have been given the opportunity to progress in my role.
My dad worked in the Building Industry for over 40 years and it’s great that the industry has come a long way to be more inclusive of women so I can now do the same.

What do you enjoy most about working in the construction/builders merchant sector?
No two days are the same and the variety of my role means there is never a dull moment. That and the many conversations about football in the office.

What achievement in your role are you most proud of?
I have two:
In 2024 I won the BMN Merchant Achiever of the Year award. Winning was amazing but being nominated by those I work with and for was even better!
I am one of three women that hold a managerial position at Chandlers. Whilst the management team is not a 50/50 split just yet it’s great that three of us hold these positions and can bring a different perspective on a subject sometimes.

Sara Day – HR Manager

1. How can businesses better support women entering the industry?
   By making their business an attractive place for women to work. We have recently reviewed our family friendly policies. We offer enhanced maternity and other family friendly benefits. We provide mentors for our new joiners and the women in the company regularly meet to support each other. We promote diversity and inclusion, strive to make our advertising attractive to women, our company attractive to women and support them so they want to stay and develop their career with us.
2. How does working in the construction and building materials industry differ from the industries you’ve worked in previously?
   I previously worked in Corporate Law firms in London so working for an independent family run merchant is completely different. I am made to feel like part of the family, as are all staff and am completely invested in wanting the company to succeed. Decisions are made collectively, there is a fantastic team spirit and I feel I can make a real difference.
3. What skills do you think are most important for succeeding in this industry?
   Excellent communication skills are essential. To deliver first class customer service, to communicate effectively with colleagues, ensuring an efficient, joined up service. Teamworking skills are also important and the ability to adapt.

Celebrating Women in the Construction and Building Materials Industry

International Women’s Day is an opportunity to recognise the achievements and contributions of women across every industry, including the construction and building materials sector.

At Chandler Materials, we are proud of the talented women across our teams who support our customers, strengthen our business and contribute to the wider construction industry.

We’re proud to celebrate the women of Chandler Materials and the important role they play in our business every day.

Whether you’re building decking, crafting furniture, or constructing a timber frame, selecting the right type of wood is essential for the success and longevity of your project. The choice between treated and untreated timber can influence not only durability and safety but also your project’s budget and environmental impact.

At Chandler Materials, we understand that every project is unique — and with our Southend branch specialising in timber, we’re here to help you choose the best option for your specific needs. Plus, our in-branch timber cutting service ensures you get materials prepared to your exact measurements, saving you valuable time on site.

What Is Treated Timber?

Treated timber is wood that has been infused with preservatives to guard against decay, fungi, insects, and other damaging environmental factors. The pressure-treatment process allows these protective chemicals to penetrate deeply into the timber’s fibres, making it exceptionally resistant to moisture and rot.

Because of its durability, treated timber is a popular choice for outdoor applications such as decking, fencing, landscaping structures, and garden furniture — anywhere the wood is exposed to the elements.

Modern treatment methods have also become far more environmentally conscious, using water-based preservatives and less harmful compounds to protect the wood while reducing ecological impact.

What Is Untreated Timber?

Untreated timber is wood in its most natural state, without any chemical preservatives. It’s ideal for indoor projects such as furniture, flooring, cabinetry, and interior framing — areas where the wood is protected from rain, pests, and prolonged moisture exposure.

While untreated timber retains its beautiful, natural grain and is easier to stain or finish, it does require more careful maintenance if used outdoors, as it’s more susceptible to warping, rotting, or insect damage.

Durability and Longevity

When it comes to durability, treated timber has a clear advantage in outdoor environments, often lasting for decades with minimal maintenance. Untreated timber, while still strong and dependable, is best suited for interior use or protected spaces where environmental exposure is limited.

Environmental and Safety Factors

Sustainability is always a priority at Chandler Materials. We carefully source timber from reputable suppliers who prioritise responsible forestry and use modern, low-toxicity treatment methods. While untreated timber is naturally chemical-free and environmentally friendly, treated timber today is much safer and cleaner than in years past.

For safety, it’s always recommended to wear gloves and a dust mask when cutting or sanding treated wood. (And remember — our Southend branch can cut your timber to size, so you don’t have to do it yourself!)

Making the Right Choice

Choosing between treated and untreated timber depends on where and how you’ll use it. Outdoor projects benefit from the added protection of treated timber, while indoor or decorative applications often suit the natural charm of untreated wood.

At Chandler Materials, our team is always on hand to help you make the best choice for your next build — whether it’s a small DIY job or a large construction project.
