Waterproofing
For high-quality, long-term protection of building structures.
Solutions to Deliver Excellence in Waterproofing
Water – as a liquid or as vapor – is one of the most destructive elements for concrete and masonry. Preventing water penetration through waterproofing is therefore an essential part of preserving the longevity of building structures.
Decades of research and development have gone into Dow’s comprehensive range of solutions for waterproofing. Offering styrene acrylic and pure acrylic emulsions for both two-component and ready-to-use waterproofing, our products allow you to deliver high-quality waterproofing solutions for applications including wet rooms, water tanks, and balconies.
Two-Component Waterproofing
Two-component (or ‘cementitious’) waterproofing systems are prepared by mixing a liquid with a powder. When set, it forms a cast-in-place, water-resistant flexible membrane.
These systems are particularly recommended for sealing and waterproofing wet rooms, water tanks, terraces, basement walls, and swimming pools – and can also be used for exterior surface protection thanks to their excellent weathering resistance.
Suitable for use on buildings and structural components exposed to periodic or long-term wetting, low hydrostatic pressure, and even high hydrostatic pressure when used in combination with the appropriate engineering.

PRIMAL™ AS-8012 R
This flexible styrene acrylic polymer emulsion is suitable for potable water. It demonstrates excellent adhesion, remarkable crack bridging at temperatures down to -5°C, and water impermeability up to 5 bar water pressure.
PRIMAL™ CM-500
This pure acrylic polymer emulsion has flexibility at very low temperatures. It offers remarkable crack bridging at -20°C, excellent water impermeability under high pressure, and excellent adhesion.
PRIMAL™ AS-48 ER
This flexible styrene acrylic polymer emulsion is suitable for potable water. It offers excellent adhesion and crack bridging properties at room temperature and exceptional water tightness under high pressure, both in fast and normal setting systems.
Ready-to-Use Waterproofing
Ready to-use waterproofing is a water-based polymer dispersion-based coating which dries down to form a seamless, flexible waterproofing membrane. It is best suited to areas that will be tiled or otherwise protected from regular foot traffic, such as internal wet areas, balconies, and decks.
