HYDROFLOW HM25 is a high-performance HDPE, cuspated drainage membrane with a 25mm profile, incorporating a non-woven geotextile, bonded to the outer face of the cuspates, therefore combining to form a geocomposite drainage membrane. This is designed to provide an effective drainage layer to the external face of water resisting structure such as podium slabs. The membrane exhibits an excellent load resistance which ensures that the free draining void is maintained for the lifetime of the structure. HYDROFLOW HM25 offers excellent chemical resistance to alkalis and organic gases making it suitable for use in a variety of ground
conditions.
HYDROFLOW HM25 is used to provide a filtered drainage plain that will provide a free-flowing void for the diversion of water away from the water resisting structure to ensure a head of water is never sustained for any period of time. HYDROFLOW HM25 is used in basement construction on podium slabs and roofs, protecting below ground structures, tunnels and
culverts.
