Yes. Gravel can be used for pipe bedding and backfilling where the project specification calls for a free-draining aggregate. The relatively uniform stone sizes allow water to move through the material while providing support around the pipe. Always follow the relevant specification for the drainage or construction system being installed.

The terms gravel and shingle are sometimes used interchangeably, particularly when describing small loose aggregates for driveways, drainage and landscaping. In practice, product names can vary between suppliers according to the stone size, shape and source. Checking the actual specification and intended application is more useful than relying on the name alone.

Bulk bag sizes can vary between suppliers, so there isn't a single volume or weight that applies to every bag of 20mm gravel. Check the stated product specification when ordering. If you need to calculate how many gravel bulk bags your project requires, speak to our team with your measurements and we'll help you work it out.

Start by measuring the length and width of the area, then decide how deep the gravel needs to be. Multiplying these measurements gives you the volume of material required. The correct depth varies considerably between a decorative garden border, pathway, driveway and drainage project, so there isn't one quantity that works for every application. If you send us your measurements and tell us what you're working on, our team can help you decide how much gravel to order.

Yes. Gravel for gardens provides an attractive, relatively low-maintenance finish for borders, paths and landscaped areas. It can also help with surface drainage and provides a practical way to cover areas where planting or turf isn't suitable. Garden gravel can be used around established planting, to define different areas or simply to add texture to an outdoor space.

20mm gravel is commonly used for driveways, paths, drainage, soakaways, pipe bedding, garden borders and landscaping. Its size makes it particularly useful where good drainage and a durable surface are priorities.

20mm gravel can be used for certain drainage, backfill and groundwork applications, but it isn't a direct replacement for a compactable sub-base such as MOT Type 1. Clean gravel contains fewer fine particles, so it doesn't bind and compact in the same way. If the project needs a firm structural sub-base beneath a driveway or paved surface, MOT Type 1 will generally be the more appropriate product.

20mm gravel is often favoured for driveways because the larger stones tend to move around less under vehicle and foot traffic than smaller gravel. A suitable base and correct installation are just as important as gravel size, though. The ground beneath the decorative layer needs to be properly prepared if the driveway is going to perform well over time.

Both 10mm and 20mm gravel can be used for drainage applications because the spaces between the stones allow water to pass through. Larger gravel generally creates bigger gaps for water movement, while the right aggregate will ultimately depend on the drainage system being constructed. Our 10-20mm gravel is suitable for applications including soakaways, drainage systems and pipe bedding.

Neither is universally better. The right size depends on what you're using the gravel for. 10mm gravel provides a finer finish and can work well in garden areas, paths and smaller landscaping features. 20mm gravel is commonly chosen for driveways, drainage and areas exposed to more regular foot or vehicle traffic. A 10-20mm gravel blend offers a versatile option when a mixture of these sizes suits the project.

10-20mm gravel is an aggregate containing stones within an approximate 10mm to 20mm size range. It is a versatile material used across landscaping, drainage, driveways, pathways and general building projects. Its combination of durability and drainage makes it useful both as a functional aggregate below ground and as a visible surface material.
