Description

Ampack Sisalex 871 - Four layer radon barrier

Four layer radon barrier consisting of two layers of PE film, a polyester fibre inlay and a 0,02 mm thick aluminium layer.

Application tips

The gas barrier is used to prevent gaseous emissions that occur naturally in the soil (radon gas, methane, carbon dioxide  and other harmful gases) or existing environmental pollution (landfill) in contaminated soil penetrating from the foundation or basement ceiling of the building into the living area, thereby protecting the occupants.

Installation instructions
Plane laying:

  • on clean layer (fine grade, lean concrete bed) between strip foundations
  • on clean layer below the floor slab (clean layer at least 5 cm)
  • directly onto the floor slab
  • within the structure of the basement ceiling (concrete, Hourdis ceilings, beamed ceiling)

Lay the dark green side (weathering side) facing up, and the PE or aluminium side against the surface. The joints should overlap by 15 cm and must be kept dry and free of dust and dirt for gluing. The same rules apply to the gas-tight laying of a vapour barrier: double-sided butyl tape for butt joints (sealing function) and application of acryl adhesive tape across the top (mechanical fixation). Edges at walls, pillars and penetrations should be 15 cm high and must to be sealed. Surfaces must be cleaned and any sharp, pointed areas and objects or any mortar remnants are to be removed in advance. Holes and offsets in the surface must be levelled out. The vapour barrier must be protected immediately after installation by applying the additional structural layers (concrete slab, insulation, underlay). When installing these layers, pay particular attention to ensuring that the vapour barrier is not stretched or shifted, and that no tears occur in the area of penetration. All tears are to be sealed. Double adhesion (sealing function and additional mechanical fixation) is necessary in order to achieve a gas-tight seal.
