Premier Pavers & Stone explains how permeable pavers can be used as a sustainable water conservation solution by preventing the precious resource from flowing into the drain.

Water is precious but city streets, walkways, backyards and driveways are often designed to allow the flow of this scarce resource into drains. When water washes over hard surfaces, it takes rubbish and pollutants along with it straight out into the ocean, exposing marine life to increased pollution levels.

While the environmental impact is serious enough, water-logged hard surfaces can be dangerous to vehicles as well as pedestrians. Slippery surfaces, for instance, make driving in the rain hazardous with an oil-and-water slurry forming on the roads. Walking through public spaces and along walkways can result in slip incidents, causing grievous injury to the pedestrian. Slippery surfaces in playgrounds and even backyards can cause injury to children.

Seeking Sustainable Solutions

Growing awareness of the problems associated with hard, impervious surfaces has led to permeable alternatives being considered for the application. Permeable surfaces, for instance, allow water to drain into the soil where it is needed while also filtering pollutants out of the waterways. The easy removal of water from the surface makes the area safer to traverse.

Various solutions have been experimented with for effective drainage of surface water into the soil including grassy lawns and materials such as gravel and stone work. While lawns require ongoing maintenance, gravel and stone work do not offer a firm surface.

A more effective solution is to use permeable pavers laid with gaps at the joints; however grass and weeds can still break through the gaps.
