Grass pavers are meant to be laid under grass or to let grass grow through them. When there is pedestrian or vehicle traffic, the pavers provide structural stability to avoid erosion, dust abatement, and mud holes. Using our plastic pavers as grass pavers has the extra benefit of making the ground surface permeable or porous. https://modutile.com/product/gravel-pavers-outdoor-basketball-court-base-24x24/
