SUDS is the Sustainable Urban Drainage System. Most natural ground surfaces, such as grass and soil, are permeable. Built up areas are very different, featuring predominantly tarmac, asphalt and other kinds of paving.
Resin has the advantage of being extremely tough as well as having a degree of flexibility under stress; this property gives it durability under impact and thermal shock. Resin also has a compressive strength that is far greater than concrete, it will dissipate loading and can increase the weight bearing limit of the base concrete.
