Controlling Stormwater

Controlling Stormwater

The expanded use of permeable pavers can be traced back to the advent of governmental mandates to control stormwater runoff in the early 90's. Today, the way stormwater infiltration is handled is a major focus of environmental regulations.


Block USA is a leading producer of permeable interlocking concrete pavers (PICP) with products such as SF-Rima™, Eco-Priora®, and Octabrick™ all specifically created to meet today's environmental guidelines. All three allow for infiltration of rainwater through the pavement surface into the ground below, controlling where and when excess stormwater is released into the surrounding area.

These solid concrete pavers are placed over a bedding course of highly permeable aggregate. The joints are filled with open-graded aggregate making the surface 100% permeable.

The pavers and bedding layer are placed over an open-graded base and subbase which create a reservoir for infiltration and storage. PICP’s ability to reduce or eliminate stormwater runoff, even in intense rain events, also reduces pollution. PICP are perfect for parking lots and low volume streets.

Below, you will find a number of case studies where permeable pavers from Block USA not only were specified to control stormwater runoff, but also to maximize land use. Because these pavers reduce the need for large retention ponds, developers were able to provide more parking for their buildings.
