New product helps with rainwater management

The d-Rain Joint system is an 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 for impervious surfaces, 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.

As a sustainable drainage system (SuDS), the d-Rain Joint is a low-cost and robust onsite storm water management alternative and can be used wherever a permeable, pervious driveway, parking lot, street or walkway is needed. By installing storm water management technology like d-Rain Joint, the water drains before it gets to the flooding stage.

The d-Rain Joint drainage channel system is less than one-inch wide and is virtually undetectable between the joints of a concrete slab. The product is highly durable material and gives storm water a path to a sub-surface drainage bed. This provides an outlet for surface water to be directed to a drainage bed and collected and held or allowed to percolate back into the soil to conform to environmental conservation and protection requirements.
