Concrete structures are covered with membranes or different materials to protect them from the damage caused by water and humidity.
Damaged concrete surfaces, caused by damp, can be cured with damp proofing treatment using mostly cementation materials.
Your home can be protected from extreme heat by installing lightweight (1/10 the weight of concrete) heat insulating blocks on the rooftop and it merely adds weight.
Cracks can be filled and cured using bonding materials to prevent further damage and it will look like brand new.
Leakages can be filled and stopped from pouring very fast using instant bonding crack injections and it even bonds while under pressure.
