Bridge Deck Coating

* MMA & PU Spray Applied Membrane
* Expansion Joints
* Combined Kerb Drainage
* Micro Concrete Jackets
* Anticarbonation
* Heat Resistant Coating

PmB forms a flexible, chemically resistant seamless membrane tough enough to outlast the design of many structures. PmB has exceptional bond strength to all commonly used substrates, has excellent crack bridging capability, a life expectancy in excess of 30 years and holds British Board of Agrément approval. Tested and approved throughout the world to the highest standards, the PmB system now adds Network Rail and London Underground (LUL) approvals to its ever growing list of accreditations.

The need for effective waterproofing solutions

Bridges are under constant stress as water, chlorides, acid rain, de-icing salts and freeze-thaw cycles act on them. Extreme weather cycles, the impact of traffi c and vibration place bridges under further stress. As steel reinforcing bars corrode and expand, concrete can crack and deteriorate. The costly disruption caused by resulting repair work impacts on both traffi c and safety.

Bridge repairs can often amount to 10-30% of the updated construction cost, and large repairs may even exceed this and still be the preferred option when compared to the cost of traffi c interruption and demolition. As moisture is the most signifi cant factor in concrete deterioration, incorporating suffi cient waterproofi ng at the design stage is by far the most cost-effective option.
