Pavement Filtration for Onsite Rainwater Management
As a Sustainable Drainage System (SuDS), the d-Rain Joint™ is a simple, low-cost, and robust onsite stormwater management alternative compared to other permeable, pervious surface options.
The d-Rain Joint™ system is composed of prefabricated devices directs the collection and conveyance of surface rainwater to an underground drainage bed for impervious and “hardscape” surfaces. This permeable pavement system (PPS) can be used wherever a permeable, pervious requirements for a driveway, parking lot, garage, large patio, Community Street, pool areas, theme parks, or public walkway is needed. The use of traditional pavement with the d-Rain Joint™ provides both permeability AND filtration at a lower installed cost! These d-Rain Joint™ devices allow the use of traditional concrete or other paver-type materials to construct a high-performing permeable, pervious surface system to put filtered rainwater in the underneath gravel detention area of the pavement; thus, increasing the usable surface, eliminating costly stormwater infrastructure or potential pollution hazards to urban ecosystems.
