It is what will give your artificial lawn structural stability.

Sub base depth for artificial grass.

The sub base is the area that s underneath the artificial turf. The best sub base for artificial grass is one that functions like native soil. The existing soil in most grass areas expands and contrasts in hot and cold and wet and dry conditions. For the best looking artificial grass use a great sub base.

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. Apply 50mm layer of 6mm to dust granno stone or grit over the weed barrier compacted using an automated whacker plate this can be hired from your local hire shop and level flat so the top of your sub base is level with the top. Artificial grass material was made porous so water can pass through if your artificial grass sub base material is not installed properly it could cause wrinkles and gaps in your turf. Uneven surfaces can create dips in your lawn and cause accidents.

We need the underside of the artificial grass to key into the sand so some give is necessary. This will not only prevent weeds but will also stabilise the sub base prior to artificial grass being laid. 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. If you ignore the sub base you could end up with wrinkles and gaps or soft spots in your grass.
