Waterproofing Membranes

WACKER offers VINNAPAS® polymer dispersions and powders for the formulation of 1K ready-to-use (pasty) systems as well as 1K and 2K cementitious systems.
GENIOSIL® WP alpha-silane-terminated polymers are key to liquid waterproofing membranes.

The portfolio comprises both polymer dispersions and powders; the vinyl acetate-ethylene (VAE) grades comply with the requirements of European ecolabels such as Blue Angel, Emicode EC1 plus, etc.

Benefits

  • Reliable barrier against both negative and positive hydrostatic pressure
  • Water vapor permeability
  • Bridging of cracks due to shrinkage or settling of substrate
  • Accommodation of small movements in the substrate
  • Excellent adhesion to many different substrates
  • Excellent adhesion after water immersion
  • High flexibility
  • Increased tensile strength
  • Excellent workability and easy application
  • Application via brush, trowel, roller or machine spraying
  • Excellent compatibility with cement

Application Spectrum

  • Basement walls and foundations
  • Underground parking lots
  • Showers and bathrooms
  • Balconies and terraces
  • Multifunctional rooftops (e.g. rooftop terraces and parking decks)
  • Swimming pools
  • Sewers, canals and water pipes
  • Water tanks (including drinking water)
  • General concrete infrastructures

Polymer modified waterproofing membranes can bridge cracks caused by movement of the substrate. Liquid waterproofing membranes based on GENIOSIL® WP can be applied easily, even on wet substrates and dry very quickly.

Benefits

  • 1K system
  • Solvent- and isocyanate-free
  • Easy to apply with roller or airless spraying equipment
