Marine Aggregates

0-4mm sharp marine sand

As our sharp sand is a marine product it is a natural material and is dredged and brought to a wharf in Sussex. If the sand is unprocessed it can be used for construction fill material, structural fill material and general fill landscaping. After processing the product can be used for concrete, drainage, special re-constituted materials including beach nourishment and non constructional uses.


10mm ballast

This stone is a 50/50 combination of the sharp marine sand and 10mm gravel.

20mm ballast

Is a 50/50 combination of sharp sand and 20mm gravel, it is most commonly mixed with cement and water to make concrete for the following uses; foundations/footings, concrete slabs for extensions and shed bases, concrete drives/paths, concreting fence posts, kerb edgings and drainage haunching, cavity wall fill/retaining walls.



From the three different sizes of gravel we supply there are many different uses and facets of each;


This size of gravel is better for pathways and general decoration, although the pieces are angular they are smooth which means they easily move over each other. Although this type can be used for driveways, they are more likely to get stuck in shoe  and tyre treads or even be displaced in heavy rain. This particular gravel is very popular due to its blend of colours of cream, brown and yellow.


This sized gravel is more angular than the 4-10mm. This makes it more suitable for being used to lay driveways, being angular the stone is less likely to displace easily under the weight of vehicles.

Laying Depth: for both driveways and footpaths, we recommend a lying depth of 50mm (2 inches). These two types are most popular for making driveways as they have a hard wearing nature, due to them containing granite, basalt or flint.


20-100mm or more commonly known as ‘rejects.’ Rejects is anything over 40mm as it isn’t suitable for crushed gravel.  This is mainly the type of gravel that is used for drainage.
