Here are a few commonly known facts about concrete and moisture.
- Water is an essential ingredient of concrete.
- Hydration and evaporation control are fundamental to the concrete curing process – both moisture related.
- Concrete dries at about 25mm per month from the later of: concrete pour OR the last time it was wet.
Thinking about the moisture exiting the concrete during the drying process – what happens if it is trapped under a floor coating or membrane?
If not controlled, it causes havoc with coatings and membranes. This is a very real concern where waterproofing membranes buckle and fail… ironically due to moisture movement in the concrete, the membrane should be protecting.
SO – Can concrete moisture be controlled?
YES, the answer is found in a catalytic hydrogel treatment.
This removes the need for a surface sealer or waterproofing membrane. Surface membranes do nothing to control the moisture internally, trapping the moisture into the slab. Membranes, in fact, are faced with multiple possible reasons for failure.
Spray-applied AQURON 2000 catalytic hydrogel treatment penetrates deep into the concrete’s porosity, transforming free moisture in the concrete into a hydrogel, preventing its movement into, out of, or within the concrete.
This simple and cost-effective treatment has other benefits too:
- Applied at concrete pour provides curing equal to 14-days water curing.
- 10,000,000m2 track record in New Zealand and Australia, and comes with a 15-year guarantee – your insurance and confidence.
- Protects the reinforcing steel for the long-term, by preventing the ingress of moisture-borne contaminants.
- Hardens the concrete, and prevents dusting, by reducing carbonation.
