Cracks in the concrete roof
Concrete roofs do not always have good thermal insulation to protect them from exposure to the sun’s rays. This insulation is more expensive and adds thickness, “enough” reasons so that at the end of the day, they are not adequately included in its construction.
Because they are made of a heavy structure, concrete roofs without good thermal insulation end up suffering from their own movements of dilation and contraction due to being exposed to continuous climatic changes. The movements generate cracks and fissures in the ceiling, typical of a material such as concrete, with resistance to null expansion.
How to seal cracks in concrete roofs?
To all these evils, you must add that, by the constant exposure to climatic agents that suffer concrete walls and slabs, it ends up accelerating the deterioration of its surface, rendering them porous and therefore permeable to moisture. That is why it is so important to waterproof a concrete roof to avoid having to cover leaks prematurely.
Waterproof a cement ceiling
To repair cracks in concrete ceilings the most common treatments have to do with the application of waterproofing sheets of different characteristics, which cover the surface, sealing fissures and preventing leaks. They are known as asphalt membrane and liquid membrane. Whichever system you choose to solve the humidity in the roofs, you should start by a good preparation of the surface of the roof so that the product you choose really acts as a good waterproofing.
Preparation of the surface to be waterproofed
The first thing that you must take into account to waterproof terraces is to proceed to the deep cleaning of the base of the roof. Remove all remaining waterproofing with brushes, spatulas or other suitable elements. Remove traces of dust, mold, grease or any other dirt that prevents the subsequent sealing of the waterproofing. Wash with water, detergent, and let the entire surface dry properly before proceeding with the sealing.
