Tuff-Gard is a single component, elastomeric system of polymer-modified bitumen. The component is waterborne, non-flammable liquids, which present no storage or transportation hazards.
The Tuff-Gard System successfully addresses and eliminates the recurring problems associated with conventional membrane and coating systems.
Ease of Application
Tuff-Gard is applied on site in one coat at virtually any desired thickness. Both components are at ambient air temperature when applied, with no heat required or involved in the application. The system produces no offensive odors and no VOC emissions.
Elimination of the Major Cause of Membrane Failure
Tuff-Gard applications are monolithic, having no laps or seams to compromise the function of the membrane, thus eliminating the major cause of failure of conventional sheet membranes.
Tuff-Gard is extremely tough, having independent strength equal to or exceeding top quality sheet membranes and coatings, thus significantly reducing the risk of mechanical damage, another frequent cause of failure.
Tuff-Gard demonstrates performance superior to pre-formed and other “basic” membranes and coatings, especially in terms of flexibility, with elongation to 1800% and recovery to 95%, combined with the ability to withstand continuous thermal cycling.
Elimination of Tracking
Tuff-Gard fully bonds to the substrate, eliminating water tracking.
Major Cost Savings
Compared to conventional systems, Tuff-Gard cuts installation times dramatically, requiring less surface preparation and allowing faster completion of projects at significant labour and other cost savings, while providing a high quality installation.
We encourage and provide a disciplined approach to product application based on product excellence, quality assurance and enhanced customer service. Quality procedures have been adopted throughout all operational areas, from component manufacture to finished applications. These procedures remain in a state of continuous review and improvement via participation of the company, its distributors and licensed applicators, in an ongoing quality assurance program.
