d-Rain Joint™ Pavement Rainwater Filtration System Designed For Onsite Rainwater Management

The d-Rain Joint™ Rainwater Filtration Device for Impervious Surfaces System is a highly effective and unique design that allows the use of traditional concrete, asphalt or paver type materials to construct a high performing permeable, pervious surface system. As an exterior, linear filter drain, the d-Rain Joint™ puts filtered rainwater in the underneath gravel detention area of the pavement increasing the usable surface and eliminating costly storm water drainage infrastructure.
