Densi Proof - Concrete Waterproofing

Permanent Concrete Waterproofing, Moisture Barrier, Cure & Seal.
For the Protection of New or Old Concrete!

Densi Proof is a one coat spray on system that deeply penetrates (up to 200 mm and beyond) into the matrix of the concrete providing permanent waterproofing and protection. Densi Proof can be applied to new or old concrete to cure, purge oil etc and to seal the concrete from any contamination. Densi Proof withstands a minimum of 35 m of Hydrostatic Pressure and can be effectively applied on the positive or negative side of concrete structures.

Densi Proof will even travel into concrete against water flow (hydrostatic pressure leakage) to permanently stop water / free moisture leakage. There is minimum site disruption, allowing other trades to be able to work in the area within 1 hour of installation without compromise to the product. Densi Proof is user friendly, environmentally safe and is a one time permanent application.

It is important to point out that Densi Proof provides a permanent unique passive, non destructive colloidal silicate gel barrier. It should not be confused with temporary, soluble, weakly-linked, large pore, thixotropic gels, that are formed using sodium silicates through free lime reactions, which have proven detrimental to long-range concrete integrity. Densi Proof's technology is unique, it is NOT a sodium, potassium or lithium silicate and has stood the test of time for over 25 years.

• Permanent waterproofing of concrete, even against internal migration
• Purges out years of contamination and odours from old concrete slabs
• Industries best cure & seal for newly placed concrete
• An effective and immediate halt to contaminant ingress from any direction
• Significantly and immediately increases concrete's density
• Increases and reinforces concrete's compression and flexural strengths
• Immediately significantly diminishes permeability of concrete
• Greatly lowers and eliminates water or gas vapour emissions
• Virtually eliminates vapours such as radon etc.
• Internally produces an effective permanent colloidal silicate barrier
• Effectively halts & prevents alkali-silicate reactions in new or old concrete
• Eliminates dusting potential for new or old concrete
• Provides significant additional surface abrasion resistance
• Provides increased surface bond quality without detriment to traction quality

Densi Proof does not adversely affect concrete's visual appearance, physical characteristics, surface traction quality, or surface bond quality, meaning Densi Proof can effectively be used to enhance any Portland cement concrete installation, whether traffic-bearing or not. Densi Proof is ideal for use on all street or highway pavements, i.e., bridge decks, parking decks, airport pavements, dams, footpaths, driveways, pavers, etc., to preserve and extend performance criteria, as well as useful life span of concrete.
