Many people question if artificial grass drains well. The drainage rate of synthetic grass refers to how quickly water can pass through and be absorbed by the artificial turf’s surface. Proper drainage is crucial for synthetic grass installations to prevent water buildup, which can lead to various issues like mold, mildew, and deterioration of the turf’s backing and infill material.
How drainage is achieved in synthetic grass:
Perforated backing: High-quality synthetic grass typically comes with a perforated backing. This backing has small holes evenly distributed throughout the turf. These holes allow water to pass through the surface and into the sub-base below.
Base preparation: Before installing synthetic grass, the base is prepared to ensure proper drainage. The sub-base typically consists of compacted crushed stone or gravel, which provides stability and drainage. Proper base construction allows water to flow away from the turf’s surface.
Infill material: Some synthetic grass installations use infill material like sand or rubber granules. Infill helps to stabilize the turf and improve drainage by creating additional space for water to flow through.
Slope: Proper artificial turf installation should incorporate a slight slope to facilitate water runoff. The direction of the slope will depend on the specific site’s requirements, but it typically leads water away from structures and toward drainage areas.
