Interlocking permeable pavers are made from post-consumer HDPE plastic. We repurpose plastic that may otherwise end up in landfills. The paver’s purpose is to help create a stable, durable gravel or grass base. After installation, it is permeable, so it helps reduce material and water runoff. Depending on how it is installed, it can serve as a water retention method for your property. https://modutile.com/interlocking-permeable-pavers/
