Environmental Benefits of Permeable Paving

If you are considering installing permeable paving on your home or business, the first step is to understand how the site has been used in the past. Performing site tests will determine the infiltration rate and percolation rate of the soil. You should also learn how deep the seasonal high water table is and if bedrock is present. If an existing subgrade is too porous, you may need to use an underdrain system. Percolation tests will help you understand the depth of the base rock.

Interlocking concrete/brick paver disadvantages

While interlocking brick and concrete pavers are both durable and attractive, there are some differences between the two. Brick pavers are more flexible than concrete and can be replaced if damaged. Concrete¬†Roof restoration is more likely to crack due to the varying temperatures and moisture levels, while bricks do not. Bricks can also be slippery when moss grows on them. Concrete, on the other hand, can’t be repaired when damaged.

Pervious concrete is porous asphalt

Porous pavement is the solution to many of the environmental challenges we face today. It absorbs stormwater and recharges groundwater. It is an environmentally friendly option that meets EPA stormwater regulations and is a Best Management Practice. It is also much cheaper than traditional asphalt, paving or concrete. Generally, permeable pavement costs two to three times as much as conventional asphalt or concrete. However, it is worth considering its many benefits.

Permeable concrete is rigid

A variety of factors influence the compressive strength of permeable concrete, including its porosity, cement content, w/c ratio, and the characteristics of the aggregates. The strength of CRP and conventional permeable concrete is inversely proportional to its porosity, with an increase in porosity reducing strength by between two and three percent. The compressive strength of permeable concrete varies according to the porosity, and it is important to calculate the amount of cement needed to achieve the desired strength.


Despite its benefits, permeable paving can be costly. Maintenance is required on permeable pavements to ensure their ability to hold water and reduce runoff volume. Permeable paving also reduces sediment that can harm aquatic life and protect backwater refuges. In addition, it allows water to recharge groundwater and prevents stream erosion. It is also an effective way to reduce water pollution by capturing pollutants in stormwater runoff.


Permeable paving requires regular cleaning to keep it looking as good as new. It also benefits from periodic cleaning to prevent blockage. Under normal use, accumulation of dust is unlikely to clog the system. To remove the dust, flush it away with a garden hose. The owners of such surfaces must maintain a maintenance schedule and document the results for their own records. Listed below are some ways to maintain permeable paving.


Permeable pavements are ideal for outdoor spaces, as they can be customized to suit the unique needs of any property. Permeable interlocking pavers, for example, can be installed on walkways, plazas, and parking lots. Porous asphalt and pervious concrete can be used to resurface sidewalks and parking lots. However, you should keep in mind that permeable paving is not a suitable choice for areas that experience severe rainfall.
