Drybase Crystalline Active Slurry is a high-performance waterproofing slurry specifically designed for direct application to concrete surfaces. The active crystalline composition creates a penetrating waterproofing solution for concrete walls, floors and structures. The high coverage-per-kilogram of Drybase Crystalline Active Slurry makes it an ideal choice for tanking larger concrete structures.
Once applied to a concrete surface, Drybase Crystalline Active Slurry the active ingredients react with the free-lime and the moisture within the concrete’s capillary tracts to form crystalline complexes. These crystal formations block the capillaries and minor shrinkage cracks in the concrete and prevent moisture ingress.
Concrete is naturally porous. It contains many fine pores and shrinkage cracks, making it susceptible to moisture ingress.
Excessive moisture ingress on concrete structures can lead to structural damage and expensive repairs.
Once applied, the active ingredients in Drybase Crystalline Active Slurry react with free-lime and moisture to form crystal complexes within the concrete.
The treated concrete is now watertight whilst still retaining its vapour-permeability. It is resistant to both active and passive water pressure.
Due to its durable nature, Drybase Crystalline Active Slurry protects concrete against seawater, waste water, ground water and various chemical solutions. It is also approved for use in contact with potable water, which makes it suitable for use waterproofing structures such as water towers, reservoirs and water storage tanks.
Drybase Crystalline Active Slurry can be applied to both new concrete or aged concrete and is effective on both the pressure and non-pressure face of a structure (i.e. both positive and negative water-pressure).
Typical Areas of Application Include:
Basement waterproofing
Waterproofing pile heads and pile caps
Construction joints
Waterproofing contiguous piling and diaphragm walls
Sewage treatment plants
Bridges
Car park waterproofing
Concrete slabs (floor, roof, balcony etc…)
Water-retaining structures
Swimming pools
Channels
Drybase Crystalline Active Slurry can be used as a waterproofing solution for new concrete floor slabs.
It can be ‘sprinkled’ as a dry powder to wet concrete slabs after the initial set.
Drybase Crystalline Active Tanking Slurry can then be power-trowelled into the surface, waterproofing the slab.
