Drybase Crystalline Active Tanking 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 Tanking Slurry makes it an ideal choice for tanking larger concrete structures.

Active Crystalline Waterproofing for Concrete

Once applied to a concrete surface, Drybase Crystalline Active Tanking 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.

Section of concrete

Concrete is naturally porous. It contains many fine pores and shrinkage cracks, making it susceptible to moisture ingress.

Section of saturated concrete

Excessive moisture ingress on concrete structures can lead to structural damage and expensive repairs.

Drybase crystalline active treatment

Once applied, the active ingredients in Drybase Crystalline Active Tanking Slurry react with free-lime and moisture to form crystal complexes within the concrete.

Drybase treated concrete

The treated concrete is now watertight whilst still retaining its vapour-permeability. It is resistant to both active and passive water pressure.

Versatile and Durable

Drybase Crystalline Active Tanking Slurry

Due to its durable nature, Drybase Crystalline Active Tanking 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 Tanking 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
  • Car park waterproofing
  • Waterproofing pile heads and pile caps
  • Concrete slabs (floor, roof, balcony etc…)
  • Construction joints
  • Water-retaining structures
  • Waterproofing contiguous piling and diaphragm walls
  • Swimming pools
  • Sewage treatment plants
  • Channels
  • Bridges

Dry Sprinkle Floor Slab Application

Drybase Crystalline Active Tanking Slurry can be used as a waterproofing solution for new concrete floor slabs. It can be ‘sprinkle’ applied as a dry powder to wet concrete slabs after the initial set. It is then power-trowelled into the surface, waterproofing the slab.
