Description
A single-component, mineral coating that is simple to mix and easy to apply. Unlike conventional slurries, HydroCoat Tanking Slurry includes advanced crystallising and capillary-blocking chemicals that also enhance the bond of the coating to the substrate.
HydroCoat Tanking Slurry can be applied both internally and externally to a variety of substrates to form an effective barrier against positive and negative hydrostatic pressure, as well as non-pressurised moisture in the ground for use in damp-proofing applications.
Applied in two coats, the 2mm coating is waterproof against water pressure of up to 7 bar. In addition to increasing the bond, the penetrating crystallising chemicals react with water and the calcium hydroxide within the concrete to actively seal developing micro-cracks.
This makes HydroSeal / HydroTank 104 particularly useful as a means of isolating moisture within pile caps, ring beams and kicker joints to internal walls.
Key Benefits
- Easy to mix, single-component slurry coating
- Brush, trowel or spray applied
- 2 mm slurry coat is fully waterproof to 7 bar
- Crystallising agents penetrate deep into the substrate to enhance bond and seal capillaries and small, developing cracks
- Permanent waterproofing of a wide variety of
substrates - Resists positive and negative water pressure and so is suitable for internal and external use
- Resistant to salt contamination in masonry
- WRAS approved for use with potable water
- Suitable for application to damp substrate
- Can be part-mixed
- Vapour permeable
Typical Applications
- Basements & cellars
- Retaining walls of concrete, brick and block
- Tanks, pools, ponds & planters
