Application

Used to control water ingress in both domestic and commercial applications and where the installed membrane needs to accept a render, plaster or dab fixed plasterboard etc.

Description

High performance, studded HDPE drainage membrane suitable for installation on internal walls, soffits and floors as an effective barrier against light water ingress. The preformed studs create a void allowing water that has penetrated the sub-structure to be effectively drained. On the face of the membrane a welded mesh allows plaster and renders to bond effectively to achieve dry and durable finishes.


Hydroflow membranes have a life expectancy compatible with the life of the structure into which installed. The membrane is chemically inert and resistant to water, alkalis and saline solutions.


Priming:

Should be primed with Hydroflow Primer.


Ancillary components:

Can be used with the following to create a complete drainage solution:

  • Hydrochannel.
  • Hydroflow Butyl Tape.
  • Hydroflow HP Corner Tape.
  • Hydroflow QS Plugs.


Features and benefits:

  • Rapid and easy installation by semi-skilled operatives.
  • Simple application to most substrates.
  • Minimal surface preparation prior to installation.
  • High compressive loading stability.
  • High drainage capacity.
