Permeable Pavement Systems

Permeable pavement also known as pervious or porous concrete is a specific type of pavement with a high porosity that allows rainwater to pass through it into the ground below.

Permeable pavement systems. Permeable pavement systems are green stormwater infrastructure gsi practices that can reduce runoff while supporting vehicle and pedestrian traffic. Permeable pavement catches precipitation and surface runoff storing it in the reservoir while slowly allowing it to infiltrate into the soil below or discharge via a drain tile. They can be made of pervious concrete porous asphalt or permeable interlocking pavers. Permeable pavement surfaces typically include pervious concrete porous asphalt paving stones and interlocking pavers.

The complete guide to permeable paving systems permeable paving systems are porous so they allow water to infiltrate the pavement and drain into the ground or sub base rock underneath. Other more traditional types are pavers in brick solid concrete pavers and cobblestones. Permeable pavement systems are an alternative to other pavements and stormwater control measures in areas where mitigating the adverse impacts of stormwater discharges is an objective or requirement. These paving systems are just as strong and durable as traditional paving materials such as concrete asphalt or compacted gravel.

Permeable pavement is a porous urban surface composed of open pore pavers concrete or asphalt with an underlying stone reservoir. The key to creating permeable driveways with these materials is to fill the gaps between pavers with sand. Permeable pavers can be little more than a concrete version of the plastic grid systems by replacing the plastic with open cell concrete blocks. Permeable paving systems are porous so they allow water to infiltrate the pavement and drain into the ground or sub base rock underneath.

Permeable pavement is a good example of a practice that catches water where it falls. Systems can be used in a wide range of applications but are most commonly sited in light duty traffic areas. For centuries engineers and architects have known that the arch is the strongest shape known to man. Unlike traditional impervious paving materials permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and or soil below.
