Porous asphalt, concrete and pavers are becoming more and more popular in construction practices. They allow water to filter and flow through them, greatly decreasing problems associated with runoff. Asphalt and concrete are engineered to have extra spaces (pores) that allow water to trickle straight down at the point of contact and enter a storage area (a sand and gravel sub-base) beneath the surface. Pavers are basically bricks that are placed in such a manner that water runs off into the crevices and filters into a storage area.

The following products can be used almost anywhere, commercially in large parking lots or on residential streets and driveways. They are designed to hold a large amount of water and to filter quickly.
