Uraflex Traffic Bearing Waterproofing System
Polyurethane Elastomeric Traffic Bearing Waterproofing System for Vehicular Parking Decks
Description

Uraflex Traffic Bearing Waterproofing System is a high-performance parking & vehicular deck protective coating system. Uraflex Traffic Bearing Waterproofing System is engineered to waterproof and protect concrete slabs from harsh environmental conditions and salt contamination. The system is formulated with a combination of highly elastomeric polyurethane technology allowing the system to bridge post application cracks and a durable, aggregate laden topcoat to withstand heavy vehicular traffic.

Advantages
  • High abraisan resistant and elastomeric
  • Chemically resistant coating
  • Maintains elasticity at very low temperatures
  • Outstanding penetrating adhesion to concrete
  • Bridges crack up to 1/16" (1.6mm)
  • Non-skid and decorative
  • Waterproof
  • Potential LEED credits (Renewable Materials)
  • Odour and Solvent free; minimal disturbance to tenants
  • UV resistant topcoat available
  • Easy to clean
Uses

Uraflex Traffic Bearing Wateproofing System is intended for use as a protective waterproofing parking deck coating system for the protection of concrete slabs in parking structures, pedestrian walkways and plaza decks. It is ideal for parking decks, ramps & drive ailes, parking garages, plaza and exposed decks, terraces and balconies (See Uraflex 360/375 UV Balcony System)
