Grit is a hard, coarse-grained, siliceous stone. Commonly used as a drainage material. It can also be used for driveways and footpaths.

Grit also makes a great option for arts and crafts by simply sticking them with PVA glue when using for scenery, gardens or paving/paths, these grits are also ideal used loosely as a substrate. Also can be used in fish tanks, some for covering compost in pots of trays or seeds, and as a mulch for succulents in pots.

Whether being used in a concrete mix or to provide support for block paving and patios, it plays an important part in any construction project.
