Moisture Proof

Con-Treat are specialists in cost effective, concrete moisture barrier solutions...

Moisture Proof is a simple to apply, single part, liquid moisture barrier and densifier for concrete. Application is by pour & spread or spray application. A soft bristled broom is used to spread any pooled areas and to obtain even coverage. Moisture Proof penetrates deep (up to 100mm) into the concrete's capillaries where it forms an internal moisture barrier. This non-destructive colloidal gel is permanent and able to withstand hydrostatic pressure.

Moisture Proof is extremely cost effective and replaces messy & time consuming two part epoxy moisture barrier systems. It has a long shelf life and allows early access with minimal site disruption. Moisture Proof is trafficable within one hour of application and floor coverings or preparation work can be carried out 24 hours later in a majority of cases. Moisture Proof has been designed for use with concrete of any age.

Note:CRACKS are always a problem for the installer. So often the client is asking for the installer to take risks and responsibility for repairing cracks that should be referred to the engineer or builder for a recommended crack repair procedure that takes away the responsibility of possible failure from the installer. This is especially the case in regards to structural cracking where the void is full depth of the concrete. In this case, Moisture Proof should be applied first before applying your normal crack repair system. In most cases, cracks are not full depth and are only micro or surface cracking, commonly caused by rapid surface drying or plastic shrinkage which would be not effect the efficiency or the result of Moisture Proof. It is worth noting that Moisture Proof is not designed or makes claim to fix cracks, however there are many applications where moisture has migrated through cracks of 1mm (even with hydrostatic pressure present) that have been eliminated permanently.

Frequently Asked Questions:

  • Question - What is the coverage rate of Moisture Proof?
  • Answer - Moisture Proof will treat approx 4m2 per ltr, porosity dependant. If the concrete is a low Mpa or is porous/open in nature, then more product will be required.
  • Question - What size pails does Moisture Proof come in?
  • Answer - Moisture Proof is available in 5 ltr & 15 ltr pails.
