The Triflex Crack Dressing is a fleece-reinforced waterproofing system for the repair of parking decks, to be used as a local measure for the waterproofing of moving separation cracks, areas at risk of cracks and construction joints. The system is made of fast-curing polymethylmethacrylate resins (PMMA) and has been specially designed for multi-storey car park traffic. It can be used as a permanent waterproofing system that withstands high mechanical loads but also as a quick temporary solution in order to reliably protect the structure from penetrating moisture.
