FreDrain® Strip Filter Drainage
PREFABRICATED HDPE DRAINAGE STRIP FILTER
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.
ADVATAGES OF FREDRAIN® STRIP FILTER
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%).
APPLICATIONS
INSTALLIONS INSTRUCTIONS – SUB SOILS INSTALLATION
A. Splice the joint by folding back the filter fabrics approximately 100mm from the ends of the rolls to be connected. Interlocking 2-3 rows of core dimples and fold the fabric back over the connection. Secure the splice connection with duct tape.
B. Couplers are available for FreDrain® Strip Filter. Slide one end of the drain into each side of the connector. Secure fitting to FreDrain® Strip Filter using duct tape.
A. End outlets are available for 300mm FreDrain® Strips. Also available universal end outlets can be used for all FreDrain® widths.
B. Universal tee outlets can be used with for all FreDrain® widths.
C. Side outlets are available for 300mm FreDrain® Strips. Also available are universal side outlets to be used for all FreDrain® widths
