fully bonded system 

    RENOLIT ALKORPRO system is a technology using a new generation of fully bonded membranes that provide an outstanding sealing performance, recommended where concrete structures must be protected against groundwater, contaminants, and ground gases like radon.

    It is suitable for waterproofing of foundations, basements, tunnels, underground parkings and all other concrete constructions below ground level.

    RENOLIT ALKORPRO is an innovative solution designed to protect buried structure in all eventualities. When these membranes are used in combination with watertight concrete, a combined sealing system with high performance is formed. In this way, in the unlikely event of damage to the membrane during installation, the special anti-tracking fleece of RENOLIT ALKORPRO will prevent any lateral migration of water between the membrane and the concrete, thus not leading to the loss of the system’s sealing function.

    The advantages of RENOLIT ALKORPRO

    • Water pressure resistance
      Tested up to 5 bars.
    • Weather resistance
      The membrane can be installed in any weather conditions (from -5ºC to +60ºC).
    • Direct application
      The membrane does not need a protection layer and can be installed directly to the stabilized soil.
    • Three ways of doing the overlaps
      Either by the CEM 805 adhesive, by butyl adhesive strips or by hot air welding.
    • Redundant sealing system
      In case of a hole in the membrane, the water ingress will be blocked by the watertight concrete.
    • High flexibility
      In case of a crack in the concrete, thanks to its flexibility the membrane will not be affected and will stay watertight.
    • Self-compartimentation property 
      The water cannot move between the membrane and the watertight concrete or through the crack, because the lateral migration is blocked by the membrane.
    • Easy installation
      With just a minimal amount of accessories the installation is easy and quick.

    Efficient system

    • No need of compartments joints.
    • No need of injection pipe.
    • No need of protection layer on top.
    • No need of protection concrete on top of protective layer

    Geomembrane versions

    The RENOLIT ALKORPRO system offers four different membrane versions, all available in thicknesses between 1.2 mm and 2 mm.

    Coloured membrane -C
    The mint green geomembrane backing is environmentally friendly and allows the incorporation of certain amounts of reworked material.

    Translucent membrane -T
    It enhances the quality control of the installation by allowing a visual control of the overlaps.

    To be installed before the concrete pouring of
    the ground slabs and walls, so that the fleece
    fibres get embedded in the fresh concrete.
    Post-applied (and pre-applied)
    Can be also installed on the walls or ceiling
    after the concrete pouring thanks to the SAP
    included in the fleece. 

    Easy to seal

    The RENOLIT ALKORPRO membrane can be installed very easily by mastic glue, by hot air welding or by using a RENOLIT ALKORPRO BAND (butyl tape).
