What is permeable pavement?
The Permeable Pavement system is defined as an engineered hard surface with porous areas which captures and temporarily stores stormwater runoff. The captured stormwater is then exfiltrated through an underdrain system, or allowed to infiltrate in to the sub-soil, thus recharging the water table. These systems including but are not limited to Porous Concrete, Permeable Interlocking Concrete Pavers, Permeable Concrete Paver Systems, Concrete Grid Pavers, and Plastic Turf Reinforcing Grid.
Permeable pavements are comprised of a layer of pavers separated by joints that are filled with small stones, and an open-graded base, such as crushed stone layers that do not contain small or fine particles. The void spaces between these layers of stone allow water to enter between the pavers, down among the crushed stone base, and infiltrate it back into the soil subgrade. The system provides 100% surface permeability and the base filters stormwater and reduces pollutants. Plainly speaking, permeable pavements are good for the environment. They visually define vehicular and pedestrian traffic areas, reduce micro-climate temperatures and enhance tree growth. A wide variety of patterns, shapes and colors define areas and tie them in with the surrounding structures and landscape. The pavements are designed to improve the health, safety, and well-being of both people and nature.
Permeable paving is a materials and techniques which use to pave roads and that let the movement of water and allow stormwater to percolate and infiltrate through areas that would traditionally be impervious to the soil below and also in such polluted atmosphere it helps to absorb the pollutants then it would make tremendous impact.

Permeable pavement is pavement which is designed to allow water to flow through it, rather than repulsing water like traditional pavement. There are a number of reasons to choose to install permeable pavement, with some people believing that this type of pavement is better for the environment. A wide range of styles of pavement can be produced in a way which makes them porous, and many contractors are capable of installing permeable paving products. It is also possible to buy permeable paving materials at home supply stores and construction warehouses, for people who like to do their own work around the home and garden. When water hits permeable pavement, it trickles through the pores in the pavement. When the pavement is installed over gravel and sand to promote drainage, the surface of the pavement often stays relatively dry, with no standing water. From a public safety and comfort perspective, permeable pavement is very convenient because it does not allow puddles to accumulate, mak
Pavement is not a particularly environmentally friendly material. In fact, solid-surface pavement promotes water runoff, which carries pollutants into waterways and contributes to flooding. This is not the case with permeable pavement. Permeable pavement is a material that permits water penetration into the soil. It may consist of any porous surface materials which are installed, laid or poured. Permeable pavement provides an attractive surface strong enough to support vehicles while allowing water to drain into the ground, which acts as a natural filter. Permeable pavement is available in the following forms: • Porous concrete. Porous concrete is similar to regular concrete except that it has minimal sand. This leaves voids for the passage of water. • Grass pavers. Grass pavers are plastic or concrete grid systems filled with gravel, mulch or grass to fill the voids. • Porous asphalt. Porous asphalt, also called bituminous permeable paving, uses the same mixing and application equipme
