Permeable Paving is a "new" market for the United States. Its been around for centuries in Europe and elsewhere. Our Customer's share our same values on working with the environment, and create beautiful sustainable paving solutions that last a lifetime, without negatively impacting our planet! We only sell the Ecoraster product range from Purus Plastics because it is the best made, highest quality cellular confinement Geogrid in the world! There are other competitors that do a good job, but we believe good is not enough.
