Water Permeable Concrete Pavers

Permeable paver stones allow water to flow down between the joints of stones and into the sub base drainage layers where water is stored until it is eventually absorbed into the soil below.
Water permeable concrete pavers. Belgard permeable pavers mimic the w. 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. 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 pavers are different from pervious and porous pavers in that rainwater passes around the paver opposed to through it.
Permeable pavers present a solid surface but allow natural drainage and migration of water into the earth by permitting water to drain through the spaces between the pavers. The interlocking concrete pavement institute estimates that permeable pavers can drain 4 to 9inches of rain per hour. The key to creating permeable driveways with these materials is to fill the gaps between pavers with sand. 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.
Permeable pavement surfaces typically include pervious concrete porous asphalt paving stones and interlocking pavers. Paving systems that use hardscape surfaces concrete asphalt or compacted gravel will collect stormwater causing it to pool or run off. Permeable concrete pavers on the other hand have wider joints up to 1 2 inch and the joints are filled with fine gravel that allows surface water to pass through. Permeable pavers are composed of a layer of concrete or fired clay brick.
Permeable pavement is a porous urban surface composed of open pore pavers concrete or asphalt with an underlying stone reservoir. The pavers are separated by joints filled with crushed aggregate. Other more traditional types are pavers in brick solid concrete pavers and cobblestones.
