Many older buildings are constructed with concrete slabs and walls which have an inherently low fire resistance. When upgrading these buildings, it is often necessary to increase the fire resistance of the structural elements to bring the building into line with present building regulatory requirements. This upgrading can be a costly and time consuming part of the renovation contract. Fortunately, Promat systems can provide speedy, cost effective and aesthetically pleasing upgrades to fit most budgets.
Why concrete upgradation
The fire resistance of a reinforced concrete structure depends to a large extent upon
1. The overall thickness of the section (in order to keep heat transfer through the member within acceptable limits)
2. The average concrete cover to the reinforcement (in order to keep the temperature of the reinforcement below critical values)
