EZflow® Gravel-Free French Drain System

The EZflow® gravel-free French drain is a pre-assembled bundle filled with lightweight patented Poly-Rock™ material for increased void space and 30% better flow rate than gravel and pipe systems. Available with and without pipe.

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
