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.
How it Installs
Easy to install like a standard expansion joint and virtually undetectable between concrete slabs, the new d-Rain Joint® PPIC (flexible plastic) channel-inserted filter captures sediment to ensure it’s continued effectiveness of the system at a maximum rate of 5 GPM/linear foot.
Finding the Right Size
It is recommended to check what local regulations are required in case additional information is needed.
