Permeable Pavers

Permeable interlocking concrete pavement (PICP) is a type of permeable paving system comprised of a layer of concrete pavers separated by joints filled with small stones. Water enters joints between solid concrete pavers and flows through an “open-graded” base, i.e. crushed stone layers with no small or fine particles. The void spaces among the crushed stones store water and infiltrate it back into the soil sub grade. The stones in the joints provide 100% surface permeability and the base filters storm water and reduces pollutants.

Features and Benefits of Permeable Pavers

  • Permeable pavers reduce or eliminate storm water detention and retention ponds, storm sewers, drainage appurtenances and related costs.
  • Increased income potential from increased lot utilization due to reduced or eliminated storm water basins.
  • Permeable pavement surface increases curb appeal.
  • Provides 100% permeable surface by runoff passing through small, open-graded aggregate-filled openings between solid high-strength, durable concrete pavers.
  • Helps meet local, state, and provincial storm water drainage design criteria and provides compliance with U.S. national Pollutant Discharge Elimination System (NPDES) regulations.
  • Meets U.S. Environmental Protection Agency storm water performance criteria as a structural best management practice (BMP) while providing parking, road and pedestrian surfaces.
  • LEED point eligible for Sustainable Sites, Water Efficiency, Materials & Resources and/or Innovative Design; Contributes to Green Globe points.
  • May be used on sloped sites with proper design.
  • No curing is required. The paver surface may be used when installed and may be designed to display an array of patterns.
  • Snow plowed with typical removal equipment; reduced winter ice hazards, de-icing salt use and snow removal costs.
  • Reduces runoff temperatures thereby preserving aquatic habitats
  • Infiltrates, filters and treats storm water runoff from conventional impervious pavements and roofs.
  • 50 year life-cycle for surface

Can PICP save money on project costs? Yes. When total project costs are factored, PICP may be cheaper than other paving solutions (pervious concrete and porous asphalt) due to multiple benefits from PICP. One example is gaining storm water management infrastructure with the money spent on paving.

How does a Permeable interlocking concrete pavement stack up against pervious concrete or porous pavement (asphalt)?

Permeable interlocking concrete pavement (PICP), because it is factory-manufactured, has a consistency in quality, can be mechanically installed, can be installed even in freezing temperatures, and is immediately traffic-ready. Pervious concrete and porous pavement is delivered to the jobsite in a plastic state. This makes them subject to weather and other conditions. PICP can be installed in freezing weather, however the other pavements cannot. In above freezing temperatures, plastic asphalt and concrete mixes must be regularly checked by the contractor for consistency and conformance to specifications. These plastic materials impose time limits within which the contractor must work and perform before the asphalt cools and the concrete cures and stiffens. The time and temperature constrained materials rely on a high degree of site control in order to achieve a successful installation.

In contrast, PICP units are manufactured in a factory and delivered to the site. They are not subject to time and temperature limitations. Permeable pavers require manufacturing standards of high compressive strength concrete averaging 8,000 psi. Pervious concrete has a typical compressive strength of about 2,500 to 4,000 psi. Unlike concrete or asphalt our concrete pavers have freeze-thaw durability test methods and requirements within their product standards to help assure adequate field performance in winter conditions. PICP offers a more durable surface under wheel loads, snow plow abrasion and deicing materials.
