What is Ecoraster Permeable Paving? And why is it important?

Posted on November 14, 2014 · Posted in Purus updates

Permeable paving or flexible porous paving is used as an alternative to the traditional use of asphalt or concrete for mud reduction and ground reinforcement. Paving is used to protect pedestrians and vehicles from mud and provide a stable, level surface for transportation. Asphalt and concrete have been used for this purpose for many years. We are now realizing that paving the ground seals the ground and does not allow the rain water and natural precipitation to get absorbed where it lands. Instead, all the runoff from natural sources enters our sewer systems, bringing with it all the pollutants that were sitting on the surface. Our sewer systems can’t always handle the run off especially when faced with changing weather patterns and more severe storms. The subsequent flooding is damaging and expensive.

There is now a focus on finding alternatives to traditional paving methods. Alternatives that help eliminate destructive run off. Our European neighbours have been using permeable paving, such as Ecoraster, for decades. European City Centres are densely populated and land is at a premium. They are forced to incorporate permeable alternatives into their designs. Permits and zoning is only granted when permeable alternatives are used in lieu of solid surfaces.

How is Permeable Pavement installed?
The base build up for permeable/porous pavers is very similar to that of traditional asphalt. The area is excavated and filled with clear 3/4 clear aggregate. The depth of excavation will depend on two main factors: What is the weight load required to bear and how much storm water do you need to buffer? Less depth can be excavated for reduced traffic areas. The porous pavers are then placed on top of the aggregate base and then filled with HPB or 1/4 clear angular aggregate. Paving systems such as Ecoraster are lightweight and fast and easy to install, even for the layperson.

What are the different types of Permeable Paving?
There are many permeable paving products currently on the market with additions regularly. There is porous concrete, porous asphalt, and porous interlocking pavers. There are also porous plastic pavers such as Ecoraster. Ecoraster is different than the others in many ways; affordability, ease of installation, carbon footprint, percentage of permeability and range of applications, just to name a few differences.
