Applikasjon
HYDROFLOW HM8 should be fixed to the outside of the structure to provide an effective drainage void. If the HYDROFLOW HM8 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 HM8 in position until backfilling has taken place.
If the HYDROFLOW HM8 is to be installed directly against concrete or masonry, then it may be fixed mechanically at one 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.
HYDROFLOW HM8 is predominantly used for vertical applications. When installed, ensure the geotextile faces outwards and a maintainable perforated land drain should be installed at the base of the retaining wall, at the same level or lower than the underside of internal structural slab, to drain the water away from the structure.
Beskrivelse
HYDROFLOW HM8 is a high-performance HDPE, cuspated drainage membrane with an 8mm 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 applied vertically to the external face of water resisting structure such as double sided retaining walls. The membrane exhibits an excellent load resistance which ensures that the free draining void is maintained for the lifetime of the structure.
HYDROFLOW HM8 offers excellent chemical resistance to alkalis and organic gases making it suitable for use in a variety of ground conditions.
