Hydroflow HP
Application

Used to control water ingress and to create a watertight environment in soil retaining structures, including basements, car parks, tunnels, vaults, etc.

Description

High performance, studded HDPE drainage membrane suitable for installation on internal walls, soffits and floors as an effective barrier against water and gases, whilst the preformed studs create a void allowing water that has penetrated the sub-structure to be effectively drained. Hydroflow HP is available with two different stud heights. The 8 mm stud is used for the control of light water ingress, the 20 mm stud is used where the control of high volumes of water ingress is required.

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, saline solutions and organic acids. The membrane does not support bacteria and fungi growth.

Features/ Benefits:

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

Applications:

Used to control water ingress and to create a watertight environment in soil retaining structures, including basements, car parks, tunnels, vaults, etc.

Priming:

Should be primed with Hydroprufe 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.
