We pride ourselves on partnering with suppliers, such as Hacker Industries (Firm-Fill Products) and Thermal Cork Solutions as their Canadian Manufacturers Representative , and will constantly deliver the highest quality solution, on time and on budget.

Our newest offering MBC Products (MgO Board Canada Products). which is 4 ft x 8 ft magnesium oxide panels in 1/4", 3/8", 1/2" and 3/4" thicknesses. These products are water resistant, rugged panels for walls and flooring that provide up to 2 hour fire ratings and lighten the floor load by over 50% versus plywood/OSB and lightweight concrete toppings.

As well we have worked with a polymer supplier to develop Acrili-Bolt, a new nano particle penetrating sealer for use over concrete floors, GFRC Castings, and gypsum flooring as a sealer/temporary protective coating. This sealer has extraordinary water and abrasion resistance properties. Acrili-Bolt can be use in both interior and exterior applications.

This experience has allowed me to develop a network of specialists across Canada to help me find the best solutions to your specific problems.
I offer set and shrinkage control additives for gypsum and for specialty cements as well as polymers in both liquid and powder forms.
In the end, my goal is to provide you with the best materials and solutions for your specific needs.
