d-Rain Joint™ Exterior Linear Filter Drain | Economical Solution for Stormwater Runoff

The d-Rain Joint™ is an innovative, cost-effective method for creating permeable, pervious surfaces. It was developed to satisfy a permeable, pervious driveway requirement while addressing LEED and NAHB greenbuilding guidelines. It has a moderate installation cost and a very low life cycle cost compared to other permeable, pervious surface options. Its simple and unique design allows the use of traditional concrete, asphalt, or paver materials to construct a highly performing, permeable, pervious surface system and provide groundwater recharge opportunities.
Advantages of the d-Rain Joint™
- Cost-effective - Adds nominal costs to standard pour-in-place surfaces.
- Easy installation - Installs using standard practices and equipment.
- Low-maintenance - Simply clean or replace filter.
- Immediate storage capacity - With aggregate type/depth tailored for local needs.
- Strength and durability - Safe for heavy vehicles and snow removal.
- Treats stormwater onsite - Environmentally sound option to contain runoff onsite.
