This phenomenon will be seen after 1 year of use because at this time the concrete shrinks, the difference between temperature, sudden sunshine and rain will contribute to this ceiling seepage.

The second reason for the concrete ceiling to be permeable is due to the structural change of the material. The material surrounding the roof, but the structure, the steel and the concrete roof is not up to the mark, besides, the poor quality concrete also leads to this situation.

With ceilings leaking from the roof, you should apply the method of sealing cracks in the gutters. At the same time, use a mixture of cement sand and waterproofing agent with a thickness of 1cm. If in case the sealing station is not effective, you should use thin sheets of corrugated iron to cover the cracks with water. Or simply use shallow gutters with deeper gutters, or drill more drain holes to prevent water from spilling onto the roof.

The second case is that the ceiling leaks at a moderate level, which will show signs of yellowing, patchy, and crow’s feet. So the solution would be to use anti-system paint with quick-drying properties.

Asphalt is often used to waterproof ceilings and walls

Asphalt is also a widely used material in construction and is also used to waterproof concrete ceilings.

Before conducting waterproofing for the ceiling, you should clean the ceiling to make sure the surface is clean, free from dirt or sand. Then apply a layer of asphalt primer and wait to dry.

Next proceed to spread asphalt on top. If in the case you use asphalt stickers, they must be glued in a straight line, not folded. Adjacent side flaps overlap 10cm, the end glued 15cm. At the intersection with the wall, you should stick 15cm on the wall to avoid standing water here.

Waterproofing concrete ceiling with self-adhesive waterproof membrane

The second method is to use a self-adhesive waterproofing membrane to overcome the situation of the concrete ceiling being permeable. The self-adhesive waterproofing membrane is in sheet form and covered with a thin layer of HDPE film on the surface. HDPE is High Density Ethylene, which is a plastic with ca. Therefore, this substance is often used in pipelines, water supply pipes, not leaking, not affected by external factors such as salt, acid and alkali even in acidic rainwater. The other side will be protected by a silicone film.

This membrane has a flexible waterproof membrane, manufactured from a mixture of bitumen rich and selected polymers APP (Atactic Poly Propylene), which is heat resistant, UV resistant and highly waterproof.

The advantage of this method is that it is absolutely waterproof, safe and friendly to health as well as the surrounding environment, non-toxic. With high applicability, you can not only use this method to waterproof the ceiling, but can also use it to waterproof the adjacent wall joints, water reservoirs and water tanks.

The disadvantage of this method is that the construction process is more complicated than other methods. Besides, it is also necessary to add heating and hot-melting techniques to create adhesion. And the service life and durability are only equal to those of self-adhesive films.

Waterproofing concrete ceiling with glue

Glue is a popular waterproofing agent for concrete ceilings today. Currently on the market there are many different types of glue for customers to choose from.

The advantage of that glue is that it is easy to buy and use.
