When installing artificial grass, it is recommended to lay a 10-15 mm thick layer of sharp sand on top of the sub-base. This sand covers the sub-base and should be compacted down. Silica sand, also known as kiln-dried sand, is the preferred type to use. It is a very fine sand purchased specifically for artificial lawns.
