Bio-Microbics introduces the d-Rain Joint™, a simple, green alternative stormwater filtered drain for hard surfaces. A simple, low cost, robust permeable stormwater filter construction joint for any pour-in-place surface. The d-Rain Joint™ is an effective, low-maintenance, low-cost option for a residential driveway, parking lot, public walkway space, or any continuous hardscape surface.
