The exceptional, easy, & economical solution for stormwater runoff.


d-Rain Joint™ is a new, innovative and cost effective method for creating permeable, pervious surfaces. d-Rain Joint was developed to satisfy a permeable, pervious driveway requirement, while addressing the LEED and NAHB Green Building Guidelines. BMP’s and LID practices are highly recommended in today’s building and site designs and are increasingly required to meet stormwater management mandates. d-Rain Joint can be a part of your permeable, pervious solution.

Current permeable, pervious surface options can be expensive, difficult to install and costly to maintain. d-Rain Joint has a moderate installation cost, and a very low life cycle cost compared to other permeable, pervious surface options. The d-Rain Joint system can be used wherever a permeable, pervious driveway, parking lot, street or walkway is needed.

The d-Rain Joint system is a simple, 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. Your site Engineer or Architect can easily configure a design to solve the site design requirements for any rainfall event using simple computations.
