Concrete protection - Problems caused by physical effects

Concrete may be subject to changes in temperature and in humidity which can lead to movements and cracking within the concrete. Concrete is often required to withstand water from rainfall, to retain water in dams and reservoirs and to repel water from tunnels and subways. Environmental forces can reduce the effective protective cover that concrete affords to reinforce still and this cover needs to be replaced by weber.cem mortars to enhance the lifespan of the structure.
