Permeable Paving

Permeable paving is a paving material that allows more water to pass through. Many flash floods in urban areas are partly caused by excessive surface runoff that is not dealt with by drainage systems. According to the Environment Agency, recent UK flooding has followed a consistent pattern, and climate change is likely to cause more frequent flooding. These increased risks can impact lives and property. Permeable paving can reduce or prevent floods, depending on the type of material used.

Permeable asphalt and concrete are two common types of permeable paving. While these two materials are not completely permeable, both types can reduce stormwater runoff. The primary difference between these two types is the amount of porosity that they have. Permeable concrete and asphalt use large pieces of aggregate, while using little to no fine aggregate. In theory, permeable concrete and asphalt are permeable, as water can easily pass through the large pores.

As a result, permeable paving is better than conventional surfacing. This type of paving helps prevent erosion by directing water directly down. It also helps protect natural waterways by keeping pollutants out of stormwater drains. However, permeable paving is generally more expensive than traditional hardscape materials. However, the benefits it offers outweigh any disadvantages. So, if you are considering installing a permeable paving system, check out the pros and cons and choose the right type of material for your project.

Permeable paving helps reduce flooding and other problems associated with floodwater. It also helps reduce surface pollution and fills up groundwater resources. There are also other options to reduce rainwater reaching public waterways. Permeable paving is an investment worth making for these reasons and more. It's well worth it! It's worth the extra cost if you want your property to be more environmentally friendly and sustainable.
