Waterproofing & Reducing Permeability
Controlling water penetration integrally
Admixtures can facilitate concrete placement and control water penetration for many applications. The expected concrete exposure conditions and desired performance will determine which solution to control permeability is appropriate for the application. Local Master Builders Solutions representatives can help with the appropriate solution.
Master Builders Solutions to Control Concrete Permeability:
- Reduce permeability to minimize water penetration into concrete
- Waterproof concrete to keep water out, and concrete structures dry
Reducing Permeability
Concrete produced with a densified microstructure limits water penetration which can transport undesirable contaminants into the concrete structure. Master Builders Solutions offers innovative admixture solutions that help achieve low permeability concrete that resists deterioration and extends service life.
- Water-reducing admixtures can be used to lower water content of concrete to reduce permeability
- Silica Fume can be used to densify the concrete matrix and reduce permeability.
Waterproofing (Watertight)
Concrete produced with a waterproofing admixture that also seals hairline cracks will provide additional resistance to water penetration and provide a baseline level of waterproofing. Minimizing crack potential of concrete is also an important consideration. Master Builders Solutions provides additional solutions for optimizing water tightness in concrete.
- Crystalline capillary waterproofing admixture to densify concrete, reduce permeability and seal hairline cracks.
- Shrinkage-reducing admixtures provide moderate to significant reductions in drying shrinkage, and reduce cracking potential in concrete.
- Crack-reducing admixture will reduce drying shrinkage crack potential and crack widths.
- Macrofibers provide effective, tight crack control
