Summary
Geocomposite drainage membrane
Geocomposite drainage membrane
Application
HYDROFLOW HM should be fixed to the outside of the structure to provide an effective drainage void. If the HYDROFLOW HM is to provide a drainage void against a PREMCRETE waterproof membrane then it should be adhered to the membrane using HYDROPRUFE HCR BUTYL TAPE 100mm width to secure the HYDROFLOW HM in place until backfill has taken place. If the HYDROFLOW HM is to be installed directly against concrete or masonry, then it may be fixed mechanically at 1 metre centres. Laps between adjacent sheets are created by butt jointing the membrane sheets before folding the geotextile membrane lap against the adjacent sheet. This will ensure that no soil fines can penetrate the geocomposite membrane which may result in clogging.

Description
HYDROFLOW HM is a high-performance HDPE cuspated drainage membrane, incorporating a non-woven geotextile bonded to the outer face to produce a geocomposite drainage membrane.
This is designed to provide an effective drainage layer, externally to water resisting structures. The membrane exhibits a good load resistance which ensures that the free draining void is maintained for the lifetime of the structure. HYDROFLOW HM offers excellent chemical resistance to alkalis and organic gases making it suitable for use in a variety of ground conditions.
