If you have a path, driveway, or patio and are planning on redoing it, then you may have heard about porous paving? It’s also known as permeable paving or, rarely, pervious paving. There are a number of advantages – particularly for a patio or pathway in your yard.
Porous paving is designed to allow water to seep through it rather than letting it run off the side. Here are some of the advantages:
- They are better for the environment – and for local flood management. Because the rainwater seeps in rather than ending up in the storm drain, there is less risk of a flood. Also, the water is cleaned of pollutants as it seeps through the gravel base under the pavement. Porous pavement can also be made from recycled materials such as concrete or glass.
- They reduce irrigation costs by directing the water into the soil under the path or patio, from where it can flow into your garden.
- They often look better. As porous paving consists of a series of tiles rather than one solid surface, you can create interesting patterns. Some people like to put the stones a bit further apart and allow grass to grow between them. They also come in a wider variety of colours. Another alternative is tiny stones which give the same look as traditional asphalt – but can be laid in different colours and patterns.
- They last longer. Because the paving stones can flex, they don’t crack as easily with seasonal temperature changes and they can handle high traffic.
- They don’t reflect as much heat – especially if you live in a hot and dry climate. This helps the health of local vegetation, makes your patio more comfortable to relax on in summer, and can even help reduce heat build-up in your car.
