Frequently Asked Questions
What sizes are your pre packed bags?
Our decorative chippings, horticultural grit and play sand are supplied in 20KG pre pack bags, while shingle, building sand and sharp sand are supplied in 25KG pre pack bags. These sizes are ideal for small to medium projects and are manageable enough to load into a car or small van without specialist lifting equipment. For larger projects, we recommend our loose tipped or bulk bag options for better value.
Can I collect pre packed aggregates from your Thatcham yard?
Yes - all our pre packed aggregates are available for collection from our Thatcham yard. You can come and view the products before buying, load directly into your vehicle and take them home the same day. No waiting for delivery slots. Call 01635 865679 before visiting to check stock and opening hours, especially for larger orders or specific decorative chippings.
Is your Play Sand safe for children's sandpits?
Yes - our 20KG Pre Pack Play Sand is certified to BS EN 1177, the European safety standard for children's play surfaces. It is washed, screened and tested to ensure it is safe, clean and free from harmful contaminants. Ideal for sandpits, sand tables, nursery play areas and primary school sensory play. For larger play area surfacing, we also supply BS EN 1177 play bark and hardwood play chip in bulk.
What's the difference between Black Ice, Flamingo, Ice Blue and White Chippings?
These are all 20mm decorative chippings, differing mainly in colour. Black Ice is a deep black chipping ideal for modern, minimalist landscaping. Flamingo is a distinctive pink-red stone perfect for feature borders and Mediterranean-style gardens. Ice Blue is a blue-grey chipping that pairs beautifully with water features and contemporary designs. White Chippings give a bright, clean finish perfect for borders, pots and smart driveways. All are supplied in convenient 20KG pre pack bags.
What is the difference between 10mm and 20mm Shingle?
10mm Shingle is a finer, smoother aggregate perfect for paths, decorative borders, drainage around pipes and pot toppings. 20mm Shingle is larger and more versatile - commonly used for driveways, soakaways, concrete mixing and general drainage. Both are clean, washed aggregates supplied in 25KG pre pack bags for easy handling. The choice usually depends on aesthetics and the size of the area you are covering.
What is Whiteparish Building Sand used for?
Whiteparish Building Sand is a premium named building sand sourced from the Whiteparish area, known for its consistency, colour and workability. Bricklayers and builders prefer it for mortar mixes, bricklaying, blockwork and pointing because it produces a smooth, strong and easy-to-work mortar. Our 25KG pre pack bags are ideal for small building repairs, garden walls and DIY projects where a full bulk bag would be too much.
What is Sharp Sand used for?
Sharp Sand is a washed, coarse sand used primarily for concrete mixing, floor screeds, slabbing, paving bedding and general construction. Unlike soft building sand, sharp sand has angular grains that lock together for strength, making it essential where structural integrity matters. Our 25KG pre pack bags are ideal for laying paving slabs, mixing small batches of concrete, and garden construction projects.
What is Horticultural Grit used for?
Horticultural Grit is a clean, sharp sand-and-grit mix used primarily by gardeners and growers. It improves drainage in heavy soils, helps cuttings root successfully, is mixed into seed compost to prevent compaction, and used as a top dressing for alpines and succulents. Our 20KG pre pack bags are convenient for greenhouses, potting sheds and propagation work where smaller quantities are more practical than bulk delivery.
Can I order pre packed bags for delivery?
Pre packed bags are primarily designed for collection from our Thatcham yard, but delivery may be available on larger orders or when combined with other products. Call us on 01635 865679 to discuss your requirements and we'll advise on the most cost-effective option - whether that's collection, a bulk bag delivery, or loose tipped load for larger projects.
Do I get better value from bulk bags or pre packed bags?
Pre packed 20KG and 25KG bags are more convenient for small projects but cost more per tonne than bulk options. If your project needs more than around 500kg (roughly 20-25 pre packed bags), a bulk bag or loose tipped load usually offers much better value. For DIY, pots, planters, small repairs and top-ups, pre packed bags are ideal. Call us and we'll help you work out the best option for your project.

Frequently Asked Questions
What is the difference between Building Sand and Sharp Sand?
Building Sand (also called soft sand) has fine, smooth grains making it ideal for mortar mixes used in bricklaying, rendering and pointing. Our Whiteparish Building Sand produces a smooth, workable mortar with excellent consistency. Sharp Sand has coarser, angular grains that lock together for strength, making it the correct choice for concrete mixing, floor screeds, paving bedding and slabbing. Using the wrong sand can weaken your mortar or concrete, so it's important to choose the right product for the job.
What is Whiteparish Building Sand and why is it popular?
Whiteparish Building Sand is a premium named sand sourced from the Whiteparish area, known for its consistent colour, fine texture and excellent workability in mortar mixes. Bricklayers and renderers across Berkshire, North Hampshire and Southern Oxfordshire prefer it because it produces a smooth, strong mortar that's easy to trowel and gives a reliable finish. Our 25KG pre pack bags are ideal for small walls, repointing, repairs and DIY projects where a full bulk bag would be too much.
When should I use 10mm Shingle vs 20mm Shingle?
10mm Shingle is a finer aggregate ideal for drainage around pipes, fine concrete mixes, decorative paths and pot toppings. 20mm Shingle is a coarser aggregate more commonly used in structural concrete, driveways, soakaways and general construction. For general-purpose concrete mixing, 20mm is the standard choice. Both are clean, washed aggregates supplied in 25KG pre pack bags for easy handling and transport.
How many 25KG bags do I need to mix concrete?
A standard concrete mix uses roughly 1 part cement, 2 parts sharp sand and 4 parts 20mm shingle by volume. As a rough guide, one 25KG bag of cement mixed with approximately 50KG (two bags) of sharp sand and 100KG (four bags) of 20mm shingle will produce around 0.05 cubic metres of concrete. For larger projects requiring more than around 20 bags, it's usually more economical to order a bulk bag or loose tipped load. Call us on 01635 865679 and we'll help you calculate what you need.
Can I collect 25KG bags from your Thatcham yard?
Yes - all our 25KG pre packed building materials are available for collection from our Thatcham yard. The bags are small enough to load into a car boot, estate or small van, making them ideal for DIY customers without commercial vehicles. Trade customers are also welcome to collect for quick top-ups between bulk deliveries. Call 01635 865679 before visiting to check stock and current yard opening hours.
Can I use Building Sand for concrete?
Building Sand (soft sand) is not suitable for concrete. The fine, smooth grains don't provide the strength needed for structural concrete - you should use Sharp Sand instead. Building Sand is specifically designed for mortar mixes used in bricklaying, rendering and pointing, where workability matters more than raw compressive strength. Using Building Sand in concrete will result in a weak, crumbly mix that won't meet structural requirements.
Do you offer bulk discounts on 25KG bags?
Yes - we offer competitive pricing and bulk discounts on 25KG pre pack bags when you buy in larger quantities. For trade customers and larger DIY projects, we can offer preferential rates. If your project needs more than around 500kg of material, it's often more economical to order a bulk bag or loose tipped delivery instead. Call 01635 865679 or 01635 40009 to discuss pricing and get a quote for your specific requirements.
What vehicle do I need to collect 25KG bags?
25KG pre pack bags are sized to be manageable - most people can lift them, and they fit easily into car boots, estates, SUVs and small vans. Please note that weight adds up quickly: 20 bags is half a tonne, which may exceed your vehicle's payload limit. If you're collecting large quantities, consider multiple trips or a van, or contact us about delivery options. Our yard staff can help you load safely on collection.
Is delivery available on 25KG pre pack bags?
Pre packed bags are primarily designed for collection from our Thatcham yard, but delivery may be possible on larger orders or when combined with bulk products. For larger projects we recommend bulk bags or loose tipped loads, which are more cost-effective per tonne. Call us on 01635 865679 (Thatcham) or 01635 40009 (Newbury) to discuss the most cost-effective option for your requirements.

Why Choose Pre Packed Gravel Bags?
Frequently Asked Questions
What colours of decorative gravel do you stock?
We currently stock four main decorative chipping colours in 20KG pre pack bags: Black Ice (deep black), Flamingo (pink-red), Ice Blue (blue-grey) and White Chippings (bright white). We also stock 25KG bags of natural 10mm and 20mm Shingle. These cover most landscaping styles from modern minimalist to traditional English gardens. For larger projects or other colours, we can source additional decorative aggregates on request - call 01635 865679 to enquire.
How much decorative gravel do I need for my project?
As a rough guide, for decorative coverage at 40-50mm depth, 1 tonne of 20mm chippings covers approximately 12-14 square metres. A 20KG bag covers roughly 0.25 square metres at this depth. For driveways we recommend 50mm depth minimum. For borders, pots and planters you can go lighter. If you need to cover more than about 10-15 square metres, it's usually more economical to order a bulk bag or loose tipped load. Call us and we'll help you calculate the right quantity.
What is Black Ice Chippings best used for?
Black Ice Chippings are a premium deep black decorative aggregate ideal for modern, minimalist and contemporary garden designs. The dark colour creates striking contrast against green planting, white rendered walls, contemporary patio slabs and architectural features. They're popular for driveways where a sleek, upmarket look is wanted, as well as feature borders and around water features. Supplied in convenient 20KG pre pack bags for easy handling.
What are Flamingo Chippings?
Flamingo Chippings are a distinctive pink-red decorative aggregate that adds warmth and character to garden landscaping. They're particularly popular for Mediterranean-style gardens, feature borders, pots and planters, and anywhere a splash of colour is wanted. The natural variation in tone from pale pink through to deeper red-pink gives an attractive, natural appearance that weathers beautifully over time. Available in 20KG pre pack bags.
What is Ice Blue gravel used for?
Ice Blue is a striking blue-grey decorative chipping perfect for contemporary garden designs, water features, coastal-themed gardens and modern driveways. The cool blue tones pair beautifully with silver-foliage plants, slate paving and water. It's one of our most popular decorative gravels for homeowners creating a calm, modern outdoor space. Supplied in 20KG pre pack bags convenient for small projects and large areas alike.
What's the difference between White Chippings and other colours?
20mm White Chippings provide a bright, clean finish that reflects light and makes small areas feel larger and more open. They're ideal for borders, pots, driveways, around pools and for creating crisp contrast with green planting or dark paving. Unlike coloured chippings, white shows dirt and algae over time - we recommend pairing with a weed membrane and occasional washing to keep them looking their best. Supplied in 20KG pre pack bags.
Should I use 10mm or 20mm Shingle for my project?
10mm Shingle is a finer, smoother aggregate ideal for decorative paths, pot toppings, drainage around pipes and fine borders where a softer underfoot feel is preferred. 20mm Shingle is larger and more versatile - commonly used for driveways (where the larger stones resist displacement), decorative coverage over wider areas and general landscaping. For driveways we usually recommend 20mm. Both are natural golden-brown shingle supplied in 25KG pre pack bags.
Can I see the decorative gravels before buying?
Yes - we always recommend visiting our Thatcham yard to see the actual colours in person before making a decision. Decorative gravels can look quite different in natural daylight compared to photos on a screen, and the scale of the stone can be easier to judge when you see it. Call 01635 865679 to check yard opening hours before visiting.
Do you deliver decorative gravel bags?
Yes - we offer local delivery of pre pack gravel bags throughout Berkshire, North Hampshire and Southern Oxfordshire. Delivery is ideal for larger orders or when you don't have transport suitable for collection. For very large landscaping projects, we also supply decorative chippings in bulk bags or loose tipped loads, which work out considerably more cost-effective per tonne. Call 01635 865679 (Thatcham) or 01635 40009 (Newbury) for a delivery quote.
Should I lay a weed membrane under decorative gravel?
Yes - we strongly recommend laying a quality weed membrane under all decorative gravel, particularly on driveways and large borders. A membrane prevents weeds from growing up through the gravel, stops the gravel from sinking into the soil over time, and makes future maintenance much easier. Pin the membrane securely at the edges and overlap joins by at least 150mm. A small investment in membrane now saves significant time and cost on weeding and topping-up later.
Can I get decorative gravel in bulk bags or loose loads?
Yes - for larger projects, our decorative chippings and shingle are also available in bulk bags and loose tipped loads, which offer much better value per tonne than pre pack bags. If you're covering more than around 15-20 square metres, bulk is almost always more economical. Call 01635 865679 (Thatcham) or 01635 40009 (Newbury) to discuss bulk pricing and delivery for your project.

Why BS EN 1177 Play Sand Matters
Our 20KG Play Sand is certified to BS EN 1177, the British and European safety standard for impact-attenuating playground surfaces. This means the sand has been tested for grain shape, cleanliness and safety, making it suitable for schools, nurseries, public playgrounds and home sandpits where child safety is essential.

Frequently Asked Questions
What is BS EN 1177 and why is it important for Play Sand?
BS EN 1177 is the British and European standard that specifies the safety requirements for impact-attenuating playground surfacing, including loose-fill materials like sand. Play Sand certified to BS EN 1177 has been tested for grain size, shape, cleanliness and impact-absorbing properties, helping reduce the severity of injuries from falls. For schools, nurseries, public playgrounds and home sandpits, choosing certified play sand is essential for safety and compliance.
What is the difference between Play Sand and Building Sand?
Play Sand is washed, screened and certified safe for children's use - it's free from sharp particles, contaminants and clay binders. Building Sand (soft sand) is intended for mortar mixes and is not suitable for play areas as it can stain skin and clothing and is not tested to safety standards. Always use BS EN 1177 certified Play Sand in sandpits, playgrounds and any environment where children will be in direct contact with the sand.
What is Horticultural Grit used for?
Horticultural Grit is a clean, lime-free coarse aggregate used by gardeners and growers to improve drainage in pots and borders, mix into compost for cuttings and seedlings, top-dress alpine plants and cacti, and prevent waterlogging in containers. Our 20KG bags are professional grade and ideal for everything from small home pot plants to larger landscaping and propagation projects.
How much Play Sand do I need for a sandpit?
As a rough guide, a sandpit measuring 1.5m x 1.5m filled to a depth of 20cm needs around 450KG of sand - that's roughly 22 of our 20KG bags. For smaller home sandpits a few bags is usually enough, while school and nursery play areas often need a tipped bulk delivery. Call us on 01635 865679 with your dimensions and we'll help you calculate the right quantity.
Can I collect 20KG bags from your Thatcham yard?
Yes - all our 20KG pre packed Play Sand and Horticultural Grit bags are available for collection from our Thatcham yard. The bags are easy to lift and fit into a car boot, estate or small van. Schools, nurseries and trade customers are welcome to collect, and our yard staff can help you load. Call 01635 865679 before visiting to check stock and current yard opening hours.
Do you stock compost, woodchip and bark mulch all year round?
Compost, woodchip and bark mulch are seasonal products and availability varies through the year. We typically have the widest selection in spring and autumn when gardening demand is highest. Because stock changes regularly, please call 01635 865679 (Thatcham) or 01635 40009 (Newbury) before travelling so we can confirm what's currently in stock.
Is Play Sand safe for cats and outdoor pets?
Our Play Sand is washed and certified to BS EN 1177 for children's play areas, which makes it clean and free from harmful contaminants. While it is generally suitable for use in covered outdoor sandpits, it is not specifically marketed as cat litter and won't clump like cat-litter products. If you specifically need a pet product we'd recommend a dedicated cat litter, but BS EN 1177 Play Sand is a safe, clean choice for general outdoor sand applications.
Do you offer bulk discounts on 20KG specialist bags?
Yes - we offer competitive pricing and bulk discounts on 20KG Play Sand and Horticultural Grit when buying in larger quantities. Schools, nurseries, landscapers and trade customers can access preferential rates. For larger play area installations or major landscaping jobs, a bulk bag or tipped delivery may be more economical. Call 01635 865679 or 01635 40009 to discuss your requirements and get a quote.
