Permeable pavers are interlocking pavers that have joints between them that are filled with small stones. Because of the space in the joints between the interlocking pavers, water enters this space and flows through to a base of crushed stone layers and then into the soil below. As a result the stones in the joints, this provides 100% surface permeability and reduces storm water and filters out pollutants.
The Future of Interlocking Pavers
Last year on July 8th, 2014, we all felt the after effects of one of the biggest rain storms to hit the Greater Toronto Area. With reports of major streets completely underwater and even a major rescue operation on the GO train, storm water has become an issue as a result of all the impervious surfaces that have been created to handle ever increasing volume of vehicular traffic. As a result, this has impacted stream bank erosion, flooding and polluting of streams, lakes and rivers which also affects our source of drinking water. It should come as no surprise that cities are now looking for cost effective storm water management solutions. Permeable pavements are what cities around the world are looking at now and beyond to help combat storm water runoff. It is also something that homeowners should be considering as well to help contribute to the reduction of harmful and potentially devastating effects of storm water on our environment.
It’s “Green” = More $$$?
The cost of installing permeable pavers is comparable to the installation of standard interlocking pavers. At Toemar, we have a product called Moderna and it can be configured in a specific pattern so that it is permeable while creating the high end look of regular square-cut flagstone. In addition, the base created for permeable pavers is essentially identical with the exception of using more pervious base such as ¾ clear stone and high performance bedding (HPB) which will allow a flow through of the water into the soil base.

How does it look?
Depending on what your needs are and your taste, you can setup your permeable pavers in many different configurations for your driveway and/or walkway. You can set it up so that it looks just like a standard interlocking paver driveway or you can “green it up” as part of the natural look. Check out some samples of what people have done:
Other Benefits of Permeable Pavers
In addition to diverting water from storm sewers which goes into stream, permeable pavers can also reduce something called “heat island effect”. This effect is caused by the buildup of heat in and around cities, towns, and structures. Asphalt and concrete absorb sunlight and convert it to heat and that is why when you walk on your driveway or a mall parking lot it feels that much warmer.
Lastly, by retaining water on your property you not only water the plants but also return water to the water table on your property.
