WACKER’s sealing slurries based on VINNAPAS®dispersible polymer powders seal almost every kind of masonry and thus offer lasting water protection.
It was not until the 19th century that an extensive water-supply and sewer network was created in many parts of Europe.
“Sections of today’s sewer networks are more than a hundred years old. Back then, it was the frequent cholera epidemics that initiated the systematic construction of sewers,” explains Dr. Jürgen Bezler, business development manager for Europe in the Construction Polymers business unit of WACKER POLYMERS.
According to the Federal Statistics Office, Germany’s public sewer system totals some 515,000 kilometers in length – this is equivalent to 13 times the earth’s circumference. However, almost 100,000 kilometers, or 25%, of the existing sewage and storm-water pipes are defective.

Problem-Solving Sealing Slurries

This might not only cause soil and groundwater contamination, but also the loss of precious drinking water. Modern sealing slurries provide an ideal method of repairing water pipes and sewers. These materials already boast a forty-year tradition in the protection of buildings.
Originally, purely cementitious sealing slurries were used, though they do not provide an adequate barrier against groundwater or driving rain. Cementitious sealing slurries were later enhanced by mixing them with polymeric additives. Today’s dry mortars already contain the polymeric component in the form of a dispersible powder.
At the construction site, these dry-mortar systems thus only need to be stirred with water, simplifying matters enormously for the building industry and ensuring consistent application properties.
Sealing slurries applied beneath a tile adhesive protect walls and floors against moisture.

A Wide Range of Applications

“VINNAPAS®-based sealing slurries protect sewers, water pipes, cellar walls and foundations as well as water reservoirs and tanks,” emphasizes Bezler.
“Typical applications range from all kinds of wet rooms, to swimming pools and wellness areas, through to wastewater drains. This applies not only to new buildings but also to the wide field of concrete repair.”
Sealing slurries significantly reduce water uptake through the pores, not only lessening the damaging influence of damp, but also effectively preventing the uptake and transport of other pollutants.

VINNAPAS®

With its VINNAPAS® dispersible polymer powders, WACKER has been the global market and technology leader for over 50 years in the field of polymeric binders for modifying cementitious systems.

More than a million metric tons of VINNAPAS®polymer powders have been sold worldwide since they were first launched. The main applications of polymer-modified premixed mortars are construction and tile adhesives, exterior insulation and finish systems, self-leveling mortars and grouts, as well as plasters and repair mortars.

WACKER pioneered powder-form polymeric binders for the construction industry as early as 1957. This technology revolutionized working methods in the sector, providing the first-ever one-pack polymer-modified cementitious system. It only required water to be added on site. To this day, the system still represents a much simpler way of working, with substantial cost advantages.

The benefits that dispersible polymer powders bestow on the end product include easier processing, excellent anchorage to all substrates, increased flexibility and flexural strength, and enhanced weathering resistance. Another advantage is that VINNAPAS®dispersible polymer powders do not contain plasticizers or film-forming aids, and therefore have low emissions levels.
