Summary
Cavity drain membrane system.
Cavity drain membrane system.
Application

HYDROFLOW HP should be fixed to the wall or to the vertical face using HYDROFLOW QS PLUGS at 600 mm fixing centres. The membrane should be drilled using an 11 mm diameter masonry drill and HYDROFLOW QS PLUGS should be hammered into the hole to secure the membrane. The selvedge, along the length of the HYDROFLOW HP8, should lap onto the adjacent sheet and is sealed using HYDROFLOW BUTYL TAPE.

Once the HYDROFLOW HP8 has been installed to the vertical walls then installation of the HYDROFLOW HP20 floor membrane should commence. HYDROFLOW BUTYL TAPE should be applied between first and second row of cuspates. The adjacent sheet should then interlock by two cuspates with the HYDROFLOW BUTYL TAPE forming an effective seal between the two sheets.

The junction between the wall and floor membrane should be taped using HYDROFLOW CORNER TAPE. The same tape should also be used to effectively seal where the membrane may terminate such as at the soffit junction.

Description

HYDROFLOW HP is a cuspated HDPE drainage membrane suitable for installation on internal walls and floors. It is designed to provide a free-draining void for the collection and control of water that permeates through a concrete or masonry sub-structure. The void created by the cuspated sheet allows the water to free flow to a drainage channel or sump.


HYDROFLOW HP is available in two thicknesses. The 8 mm-thick membrane is typically used for application to vertical substrates or for the control of light water ingress. The 20 mm membrane is typically used for application to horizontal or floor constructions or where the control of higher volumes of water ingress is a consideration.
