Key Features

  • Drainage bundle comes preassembled and ready to install
  • no need to haul large amounts of stone and gravel
  • Strong structural integrity resists compaction and supports pedestrian traffic and lawn tractors when properly installed
  • Patented Poly-Rock™ material is uniquely engineered with flow channels, providing greater storage capacity compared to gravel systems
  • Flexible bundle can be cut to size, and multiple bundles can be connected together at the pipe ends with internal couplings
  • Available in 3 sizes with slotted pipe and 3 sizes without slotted pipe

Applications

  • Use for surface and subsurface drainage problems on lawns, plant beds, and sports fields, and against building foundations and basements, retaining walls, and raised planters
  • Works as an infiltration system to capture adjacent groundwater and slowly release it into the surrounding soil, or redirect water to a connected pipe for proper release downstream
  • Works in conjunction with other NDS products such as catch basins, channel drains, Flo-Well® dry well and pop-up emitters as part of a complete stormwater drainage system

Installation & Maintenance

  • Ready to install, and in half the time of traditional French drain systems; recommend install with a minimum 1% slope for positive drainage
  • Works best in non-clay soils

Materials & Sustainability

  • Poly-Rock™ made of expanded polystyrene; mesh made of polyethylene geotextile
  • Products with pipe: single-wall corrugated slotted drain pipe is made of high-density polyethylene
  • Onsite stormwater management protects the watershed downstream, and limits excess runoff which can lead to negative impacts such as erosion, pollution, and flooding
