Porous concrete is a permeable form of concrete that traps water and allows it to seep into the ground. It is popular for environmentally conscious construction as it helps manage water runoff sustainably. It can be made from recycled materials and comes in a range of colors. It has advantages in water management and safety, but may not meet structural requirements for all building applications.
Porous concrete is concrete designed to trap water and allow it to seep into the underlying soil. There are a number of benefits to this type of construction, which have made it a popular option for things like sidewalks, driveways and parking lots. It is especially popular with environmentally conscious construction companies, as it helps manage water runoff in a sustainable way. Many so-called “green” builders promote their use in their projects.
There are a number of alternative names for porous concrete, including permeable concrete, porous pavement, and permeable concrete. Basically all the names mean the same thing: it’s a form of concrete that is permeable, rather than solid. Porous concrete is produced by mixing large aggregate material with mortar, creating many voids in the poured concrete. As water lands on the material, it drips through the voids and into the ground underneath.
For people who are concerned about the environment, porous concrete is attractive because it traps water, rather than letting it drain needlessly into the ocean. It can help route storm runoff and rainfall directly into the ground, where it can feed gardens and drip into the water table. It also comes in a range of colors and can be made from recycled materials, including recycled concrete rubble. This flexibility and recycling potential make it an environmentally friendly and aesthetically pleasing building material.
From a contractor’s perspective, porous concrete has some distinct advantages in water management. Instead of allowing water to build up, it sucks in the water and drives it away. This prolongs the life of the concrete and also makes it safer for people who drive, walk and cycle, as they don’t have to contend with puddles of water. Although extremely wet conditions eventually overwhelm the absorbency of the concrete, it is still a better drainage choice than well-compacted concretes.
Because porous concrete has a lot of void space, it is not suitable for all building applications. There are specific requirements for structural concrete, for example, to ensure it is safe and sound, and porous varieties may not always meet these specifications. It can be used safely for driveways, concrete patios, driveways, sidewalks and so on. Some companies also throw bricks and tiles there for people who want to build their own tiled walkways.
