A strip filter composite drain and collection solutions, consisting of a three dimensional, high-flow drainage core, wrapped with a non-woven filtration geotextile.
FreDrain® Strip Filter is a composite drain and collection system consisting of a three-dimensional, high-flow drainage core that is wrapped with a non-woven filtration geotextile.
FreDrain® is designed to replace conventional sand or gravel-covered pipe drains by providing a far greater surface area for water to pass, resulting in faster more efficient drainage.
Available in 100mm, 200mm and 300mm depth, either 25 or 40mm thick and comes in 50m Rolls. A full range of fittings is available with the system for fast and easy installation.
The most important characteristic of any subsurface drainage system is its ability to collect drain water from the surrounding soil. Conventional pipe and stone systems have major limitations when compared to FreDrain® Strip Filter. The open area in FreDrain® Strip Filter (60%) far exceeds that of a perforated pipe (1.1%) and rigid strip filters (2.5%).
