Application

  • Below grade concrete slabs.
  • Below grade walls with both single (blindside forming) and double-faced formwork (open cut).
  • For prefabricated construction.
  • Residential and industrial buildings such as housing, commercial, leisure facilities, manufacturing plants and warehouses.
  • Engineered structures, such as retaining walls, tunnel galleries, potable water tanks, waste water storage treatment structures and tanks.

Synthetic waterproofing membranes applications should be carried out by approved applicators. The membrane does not have UV resistance but can be exposed during the application of three months - consult manufacturer for details.

Description

Pre-applied sheet membrane waterproofing system, consisting of a highly flexible polyolefin membrane and non-woven fleece. The system provides a durable, mechanical bond which is created when the fleece is adhered to fresh concrete. The membrane is cold applied, installed with heat or open flames and before any steel reinforcement is placed/ concrete is poured.

Features and benefits:

  • No need for protection screed.
  • Saves on both time and labour.
  • Fast installation: layout, jointing and detailing.
  • Weather resistant, with temporary UV-stability during installation.
  • No lateral water migration will occur in the event of damage.
  • Resistant to aggressive mediums in soil.
  • Crack bridging ability.
  • Overlapping areas are self-adhesive. No need for any extra tape to overlap.
  • High elasticity at low temperatures.
  • It is resistant to 5 bar water pressure.
  • High mechanical impact resistance.

Application:

  • Below grade concrete slabs.
  • Below grade walls with both single (blindside forming) and double-faced formwork (open cut).
  • For prefabricated construction.
  • Residential and industrial buildings such as housing, commercial, leisure facilities, manufacturing plants and warehouses.
  • Engineered structures, such as retaining walls, tunnel galleries, potable water tanks, waste water storage treatment structures and tanks.
