"I have been dealing with Con-Treat for the past 2 years. In that time the service, advice and quality of products has been second to none. Truly a company that combines old fashioned customer service with value for money."
Stuart Bourke

"I would like to thank you for your direction and advice in regard to the removal of pressure sensitive adhesive. The "Supa Sander" attachment you supplied worked a treat & has also proven very successful for many other applications. I recommend this to any other floor layer interested in saving time, money & labour fatigue."
Glen Sinclair
Asset Flooring - Brisbane
"I am extremely happy with the performance of the "Supa Sander" diamond plate. It has proven to be highly cost effective on countless projects. I have used it to level out concrete floors before laying vinyl planks & for removing acrylic adhesives from concrete slabs. A very handy tool that saves time & money."
Peter O'Leary
PDO Floors - Toowoomba
"Thank you Andrew and Sam for your prompt service. I recieved the diamond wheels and plugs today at lunchtime, not even 48 hours after ordering them. We can't even get things down from Perth that quickly! So thanks again for your advice and service."
Dave Taylor
First Class Concrete Finishers - W.A
"I have been a floor layer for 33 years and have just purchased a "Supa Sander".
It has become the most valuable tool to me for light to medium preparation work. It makes my work a lot easier and I will never go back to using sanding discs."

Concrete Waterproofing: Densi Proof
Permanent Concrete Waterproofing, Moisture Barrier, Cure & Seal.
For the Protection of New or Old Concrete!
Densi-Proof is a user-friendly, environmentally safe, white (clear-drying), non-flammable, liquid penetrate concrete protection solution that is non-toxic (has zero voc). It provides exceptional concrete waterproofing and can be applied to new or old concrete to cure, purge oil etc and to seal the concrete from any contamination.
The Densi-Proof concrete protection substance in liquid form has practically nil solids and is a one coat spray on system that deeply penetrates (up to 200 mm and beyond) into the matrix of the concrete providing permanent significant concrete waterproofing and protection. Densi Proof withstands a minimum of 35 m of Hydro-static 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 (hydro-static 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.
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.
Recent Projects
Bovis Lend Lease specified Densi Proof + Anti Microbial as a cure / waterproofing at time of pour to all ground slabs at the Gold Coast University Hospital.
Bovis Lend Lease specified Densi Proof for all ground slabs, Densi Proof + Surface Repeller for the car parks and Densi Proof + Surface Sheen for the plant rooms at the Brisbane Supreme Court.
Concrete Waterproofing the right way - The Advantages of Densi-Proof
- 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's concrete protection agent 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.
