Concrete drainage channel d-Rain Joint®

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. How it Works As a “Sustainable Permeable Stormwater BMP”, the d-Rain Joint® linear rainwater filtration device is a truly remarkable and revolutionary alternative to pervious paving that addresses surface stormwater runoff; perfect for public, commercial and private driveways, around swimming pools, patios, walkways, parking lots. These embedded devices instantly beneath the impervious, “hardscape” surface(s) at up to 5 gpm per linear foot of rainfall and drain quickly and safely into an underlying engineered drainage bed of gravel. Using low-cost, harder substrate, the solution to provide a permeable, pavement system (PPS) can be used wherever stormwater management requirements are needed for a driveway, parking lot, garage, large patio, community common areas and streets, pool areas, sports architecture, shopping or theme park developments, alleyways or public walkways.
