Permeable Aggregates (SuDS)
Sustainable Drainage Systems (SuDS) have been introduced to reduce the impact of water discharge from new and existing developments. Historically, surface water from large paved areas was discharged via a network of drains and gullies to a nearby water course such as a river or stream. It was quickly discovered that this practice prevented water from infiltrating the ground, thus preventing recharging of natural subterranean water storage.
A common misconception of SuDS is that they reduce flooding on the development site. In fact the SuDS is designed to reduce the impact that the surface water drainage system of one site has on other sites. For instance, sewer flooding is a problem in many places. Paving or building over land can result in flash flooding. This happens when flows entering a sewer exceed its capacity and it overflows. The SuDS system aims to minimise or eliminate discharges from the site, thus reducing the impact, the idea being that if all development sites incorporated SuDS then urban sewer flooding would be less of a problem. Unlike traditional urban storm water drainage systems, SuDS can also help to protect and enhance ground water quality.
Mainland Aggregates Ltd are able to offer a number of SuDS compliant, permeable aggregates both loose by the tonne and in bulk bags for use in both commercial and domestic projects. SuDS aggregates are particularly favoured by paving manufacturers who each have their own specification for how permeable aggregates should be used with their particular block.
