The commercial lawn has higher requirements on the flatness of the base surface when it is used, so that the thickness of the artificial grass surface layer can be effectively ensured, and the elasticity is uniform during use. The pass rate of flatness is above 95%, the error of 5m ruler is 3MM, the slope is 8‰ in the horizontal direction, 5‰ in the longitudinal direction and 5‰ in the semicircular area. The surface should be flat, smooth and ensure drainage.
The basis of commercial lawns should have a certain strength and stability. The surface is even and solid, no cracks, no rotten surface, the seam is straight and smooth, and the dicing is about 6000mm×6000mm. The mat is laminated, and the compactness is more than 95%. After the medium-sized roller compactor is pressed, there is no significant wheel track, no loose soil, no waves, and the like.
The cement foundation of the commercial lawn must have a water-repellent layer, and the water-repellent layer is made of a new PVC thick water-repellent film. The junction should be greater than 300 mm and the margin margin should be greater than 150 mm. Consider the expansion joints and the width is 5 mm. The basic maintenance period is 2-3 weeks.www.frengrassturf.com
