Driveways, footpaths, steps, and parking areas need to be durable and should sustain the rough usage and constant load of things moving on them. At the same time, these have to allow water to pass directly through them so that the surface stays intact, and the groundwater levels also get recharged.
Using normal concrete to pave the path for residential and commercial buildings will not let the water accumulated on the surface to seep through, leading the surfaces to become slippery. Moreover, it is not eco-friendly.
Porous concrete, on the other hand, has high porosity and lets water on the surface to sink through the pores and seep into the ground. Porous concrete is generally known as permeable concrete or pervious concrete. Permeable pavements, paths, patios, etc. are common in Australia. They prevent stormwater from flowing onto the roads and causing trouble. It allows the water to drain into the drain lines or stormwater drains below the path in very little time. This ensures that people can safely walk around the place and also saves water from being wasted.
Benefits of Using Porous Concrete
- Durability is one of the main factors that encourage people to opt for porous concrete paths, pavements, and driveways.
- Permeable concrete lasts as long as the normal concrete and, in most cases, even longer. It can support the weight of heavy vehicles and equipment without any problem.
- While concrete tends to crack and buckle when the soil beneath is washed away, permeable concrete sustains the shift in the soil as it is flexible. So, the chances of permeable concrete having potholes are less likely when compared to asphalt.
- Easy to Install
- Porous concrete is easy to install and doesn’t require any special equipment for the purpose.
- First, the ground where it would be laid is neatly cleaned and graded. Then, a layer of rock is added as a base. This step is similar to the one followed for concrete or asphalt.
- Now, grids are laid out on the path and trimmed to fit around any objects (such as a tree) in the path. The objects need not be uprooted to lay the path.
- After locking the grids together, limestone or gravel is filled and compacted to create a strong surface.
- Porous concrete is not just less expensive than concrete, but it also requires less labor. The materials can be sourced from local markets, thereby reducing the cost of transportation for shipping the raw materials from one place to another.
- Erosion Control- Environment-friendly
- The nature of permeable concrete makes it the best alternative to be used in parks and around trees without causing any damage to the roots.
- The water draining quality ensures that the roots of the trees get the required amount of water to survive. Sunlight and air also seep through the material with ease.
- Porous concrete paths not only look good and are aesthetically pleasing but can also prevent soil erosion in areas that have loose soil.
- Temporary Roads
- There are times when a place needs extra space for parking, or there is a need to lay a temporary path to a construction site. Once the purpose is solved, and space is no longer necessary, the porous concrete path can be easily removed.
- In such instances, using porous concrete to lay temporary roads or parking spaces (even in a lawn) will be time-saving and cost-effective. Also, it does not cause any permanent damage to the environment or the infrastructure of the place.
Permeable concrete is a versatile, strong, and reliable material that can be used just about anywhere and demands low maintenance in return.
