Our environment is fragile and we all have a responsibility to protect it. We are aware of the environmental impact of our activities, and the projects we are involved in, and strive to ensure this is minimal.
One major environmental concern is climate change and the resulting increase in rainfall and subsequent flooding. The Pitt Review into the summer 2007 floods found that more than two thirds of the 57,000 homes affected were flooded by surface water run-off, not by overflowing rivers.
SureSet permeable paving not only contributes to flood prevention, but also delivers a long list of other benefits including:
When permeable paving disperses surface or rain water it seeps through the sub-base on its way back to the ground. During this process, a natural filtration takes place, reducing or removing impurities and pollutants, reducing water run-off, flash flooding and water pollution caused by oils and heavy metals.
Reducing standing water (puddles)
SureSet resin bound paving is cold mixed on site using a process that ensures every particle of stone is completely covered in resin; forming a structurally stable 3D matrix. During the laying process, minute voids are created that mimic natural drainage – making it permeable.
SureSet permeable paving is compliant with SuDS (Sustainable urban Drainage Systems): an approach to water management introduced by the Environment Agency in 2011 to help manage flood risk and water quality.
Even when applied to a conventional base, the permeability of SureSet resin bound paving allows water to be harvested or discharged into drains or soak-aways.
Reducing the ‘heat island’ effect
Heat islands exist because of land surface in towns and cities, mostly consisting of asphalt and concrete, absorbs and stores heat; making it significantly warmer than the surrounding countryside — especially at night.
Permeable paving allows the soil underneath to breathe, reducing surface temperatures, especially in the hot weather, which reduces the ‘heat island’ effect.
No planning permission required
Since government legislation in 2008, planning permission is not required for areas less than 5m² or if the new surface is permeable.
