Triflex DeckDefence

A cost effective solution for internal concrete decks and ramps above parking and ground bearing decks and ramps
Find out more


Internal concrete decks and ramps over parking or ground bearing concrete decks and ramps are commonplace in UK parking structures and while these areas are generally not exposed to the same environmental influences as external decks, they are more likely to be subject to high levels of chloride contamination and abrasion. Featuring a solvent free epoxy based waterproof coating layer with an exceptionally rapid curing PMMA finish, Triflex DeckDefence is a cost-effective solution that offers the required protection and helps to minimise time on site.

The waterproof system is available in three variants which are engineered to deal with a wide range of substrate textures, from textured, profiled and uneven decks to smooth, power floated decks, and can optionally include a fully reinforced waterproofing membrane for high risk areas. The durable solution protects decks and ramps from chemicals, chloride contamination and carbon dioxide ingress, satisfies slip resistance requirements and visually improves and enhances the parking environment.

Tough and durable protection

The demands of even highly trafficked, high space change rate car parks are no issue for the aggregate filled wearing course and durable surface finish used in Triflex DeckDefence. The system is resistant to chlorides (road salts), carbon dioxide ingress, petrol, diesel, brake fluid, engine oil, battery acid, and de-icing and cleaning products. Protection that's built to last, with a low lifecycle cost.
