It is what will give your artificial lawn structural stability. Make sure you remove 60 80mm of soil before you lay down the sub base and new artificial turf as this will result in a perfect installation. This will not only prevent weeds but will also stabilise the sub base prior to artificial grass being laid. The sand is placed onto the prepared sub base roughly levelled out using a rake or a lute and then very lightly compacted just one or at most two passes with the vibrating plate compactor to firm it up without making it hard and unyielding.

A solid well compacted sub base is crucial in providing sufficient strength to allow foot traffic and items of furniture to be placed upon the artificial lawn.
