Industry Professionals Say
“From day one, the Board wanted a permeable lot, a view heightened by the long-term drought in the southeast which drastically lowered lake levels and threatened drinking water supplies. They visited pervious concrete and permeable interlocking concrete pavement projects in the region. This raised everyone’s confidence in these types of systems. The board went with PICP because of easy repairs and a better looking surface.”
“Infiltration is so high that there hasn’t been any water captured in the monitoring wells.The PICP is performing adequately being subject to parked cars, traffic and street sweeping."

PICP Installation
The ICPI website is a primary resource for design professionals and installers, and homeowners will find the information available of great value. ICPI provides several publications that can make you more knowledgeable about interlocking concrete pavements and as a result an educated consumer. Some of these resources review the steps necessary for constructing interlocking concrete pavements. Additionally there are numerous resources available from the online store, including DIY videos and ideas books.
Interlocking Concrete Pavement is commonly used for both pedestrian and vehicular applications. Pedestrian areas, driveways, and areas subject to limited vehicular use are paved with units 2 3/8 in. (60 mm) thick. Streets and industrial pavements should be paved with units at least 3 1/8 in. (80 mm) thick.
Compaction of the soil subgrade and aggregate base materials are essential to the long-term performance of interlocking concrete pavements. Drainage should also be addressed in the system.
Installation steps typically include job planning, layout, excavating and compacting the soil subgrade, applying geotextiles (optional), spreading and compacting the sub-base and/or base aggregates, constructing edge, restraints, placing and screeding the bedding sand, placing concrete pavers, compacting concrete pavers, sweeping in jointing sand and final compaction.
