Many homeowners assume artificial grass installation simply involves rolling out a carpet on top of the existing lawn. The reality is more involved — done properly, it requires thorough excavation and a well-prepared sub-base that will last the lifetime of the product.
Stage 1: Excavation
The existing lawn and topsoil are excavated to a depth of approximately 75–100mm. All organic material must be removed — leaving it in place would allow it to decompose and create an uneven surface. The excavated material is removed from site.
Stage 2: Sub-base Preparation
A layer of MOT Type 1 crushed stone is laid and compacted to create a firm, well-draining sub-base. This is the most critical stage — a poor sub-base creates drainage problems and surface unevenness that will become apparent within a year or two.
- Typically 50mm of compacted MOT Type 1
- Compacted with a vibrating plate compactor
- Finished level must be accurate — checked with a level
- Fall built in toward a drainage point where possible
Stage 3: Laying and Fixing
A weed membrane is laid over the sub-base, then the artificial grass is cut to fit and secured around all edges with fixing nails or adhesive. Joints between rolls are glued and carefully aligned so the pile direction matches throughout.
