DAMPZERO HYDRASEAL SLURRY is a one-part waterproofing system consisting of a blend of cementitious powders combined with activating chemicals, high-grade fillers and powders. DAMPZERO HYDRASEAL SLURRY can be used for both positive and negative waterproofing against dampness and groundwater as well as hydrostatic pressure.
Description
Uses
- basements
- sewage tanks
- reservoirs, canals and swimming pools
- water towers and silos
- subways and manholes
- precast concrete units
Advantages
- pre-blended (no bonding liquid required)
- easy application – applied by block brush
- block water passages – seals pores
- can be applied to wet surfaces or green concrete
- non-toxic and non-tainting
Mixing
- mix 1 x 20 kg DAMPZERO HYDRASEAL SLURRY to 7.2 litres of water to produce a suitable brush-on mixture
- DAMPZERO HYDRASEAL SLURRY is supplied in a 20 litre container suitable for mixing purposes – just add water
- occasionally stir the slurry to prevent settlement of solids
- DO NOT re-temper the slurry once it has started to set
Application
- if there is exposed reinforcement within the treatment area, coat with WJ BONDCRETE to ensure sound bonding is achieved
- ensure free standing water is removed before commencement of application
- presaturation of the area is advised before application
- apply 2 x coats of DAMPZERO HYDRASEAL SLURRY, one coat at a right angle to the other
- allow 12 hours curing time between each coat
Recommendation
- use rubber or plastic gloves to protect against cement burns
- where possible, protect the newly treated surface from frost or rain
- application should not cure too rapidly; treated area should be kept damp for 2-3 days
