Rainwater Filtration Joint for Concrete (whether decorative or traffic-loading) Surfaces. As a Sustainable Drainage System (SuDS), the d-Rain Joint is a simple, low-cost, and robust onsite stormwater management alternative compared to other permeable, pervious surface options. The d-Rain Joint device directs the surface rainwater to an installed drainage bed beneath the impervious, “hardscape” surface(s). Using low-cost, harder substrate, the solution to provide a permeable, pavement system (PPS) can be used wherever stormwater management requirements are needed for a driveway, parking lot, garage, large patio, community common areas and streets, pool areas, sports architecture, shopping or theme park developments, alleyways or public walkways.

The use of traditional concrete with the d-Rain Joint provides both permeability AND filtration with lower maintenance at a lower installed cost than a paver system! These d-Rain Joint devices allow the use of traditional concrete or other paver-type materials to construct a high-performing permeable, pervious surface system to put filtered rainwater in the underneath gravel detention area of the pavement; thus, increasing the usable surface, eliminating costly stormwater infrastructure or potential pollution hazards to urban ecosystems.

Rainwater Filtration Device Products include:

  • d-Rain Joint 6061-T6 (aluminum), <1” wide and available in 8’ lengths
  • NEW! d-Rain Joint PPIC (gray plastic), <1” wide and available in 8’ lengths (introduced at GreenBuild 2016)

Easy to install like a standard expansion joint and virtually undetectable between concrete slabs, the ADA-compliant d-Rain Joint 6061-T6 (aluminum) and the new d-Rain Joint PPIC (flexible plastic) channel-inserted filter captures sediment to ensure it’s continued effectiveness of the system at a maximum rate of 5 GPM/linear foot.

The product is highly durable and gives stormwater a path to a subsurface 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.

The d-Rain Joint PPIC Device is stackable to 4”, 6”, and 8” height from patio installations to heavy-traffic pavements.

  • 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.

We can assist you with (Typical 16’ x 24’sizing and custom designs) Driveway Calculations*.

  • to calculate the performance of the permeable driveway system, we start with the square footage of the driveway and typical rainfall statistics for the location of the project.
  • Final Performance Calculation will be dependent on the void-to-solid ratio of the stone gravel bed available and absorption rates of the soils in the local geographic area.
  • If using asphalt, other installation considerations and procedures may be necessary.

Stormwater runoff is a major cause of water pollution in urban areas. When rain falls on our roofs, streets, and parking lots in cities and their suburbs, the water cannot soak into the ground as it should. Stormwater drains through gutters, storm sewers, and other engineered collection systems and is discharged into nearby water bodies. The stormwater runoff carries trash, bacteria, heavy metals, and other pollutants from the urban landscape. Higher flows resulting from heavy rains also can cause erosion and flooding in urban streams, damaging habitat, property, and infrastructure.

When rain falls in natural, undeveloped areas, the water is absorbed and filtered by soil and plants. Stormwater runoff is cleaner and less of a problem. Green infrastructure uses vegetation, soils, and other elements and practices to restore some of the natural processes required to manage water and create healthier urban environments. At the city or county scale, permeability is required for hardscaped and impervious (concrete) surface area to prevent flooding stages and alleviate the strain on storm drain networks. At the neighborhood or site scale, stormwater management systems that allow permeability to “drain the rain” to local aquifers and groundwater sources are an ecologically and economically responsible solution.
