Duron Traffic Topping Systems

Traffic Toppings

New and existing reinforced concrete structures must be protected from the severe attack of road salts on reinforcing steel. Traffic toppings are selected and designed on the basis of the amount of traffic exposure, desired service life, thickness and weight. Each system provides protection against salt migration into the concrete and has inherent strengths and weaknesses that require careful consideration.

Duron's epoxy and polyurethane "thin" traffic topping systems have been installed across Canada and The United States for over forty years. While thin systems require care in high traffic areas, they use less headroom and are the lightest systems available. A waterproof non-slip wearing surface is applied over a polyurethane waterproofing membrane to a thickness of approximately 1/8" and an approximate weight of 2 pounds per square foot.

For maximum protection and economy, Duron's hot process DuroMastic is the ideal solution for interior parking decks. The system includes a flexible waterproofing membrane as well as a tough mastic waterproof wearing course. This system is approximately 1/2" thick and has a weight of approximately 8 pounds per square foot. Duromastic is ideal for interior parking areas and heated ramps.

Asphalt membrane systems are the most economical choice for parking decks and exterior environments. While asphaltic concrete wearing courses are permeable to water and salts, they are placed upon hot rubberized waterproofing systems which protect the concrete from salt intrusion. These systems are ideally suited for exterior parking decks as well as truck and snow plow environments. The system has an approximate thickness of 1.5" and weight of 15 pounds per square foot.

Concrete toppings on waterproofing membranes provide excellent resistance to salt damage and heavy traffic environments. A combination of high strength concrete on top of an asphaltic waterproofing membrane provides the toughest resistance to wear. Applied at a minimum thickness of 4", this system weighs approximately 50 pounds per square foot.

- Can be used for heat cable installations. - Asphalt wearing course NOT waterproof.
- May require periodic re-sealing.
- Not available in winter months.
- Subject to softening with prolonged exposure to petroleum products.
- Requires the use of bi-level drains.
- High weight (15-25 psf) - may not be suitable for some existing garage decks.
- Greater thickness - may impede allowable height clearance.
Concrete:
- Resistant to abrasion (good for snow plow traffic).
- Suitable for direct UV exposure.
- Suitable for the heaviest of traffic.
- Can be used for heat cable installations.
