EVERYTHING ABOUT ROOF WATERPROOFING

Signs of roof leaks:

• The terrace surface begins to appear cracks, crow's feet, cracks that expand over time.

• The floor of the terrace is tilted, the tiles are blown up or broken.

• The terrace has moss that causes loss of aesthetics.

• The ceiling under the terrace appears to be leaking, water from above flows down to the ceiling when it rains.

What causes the roof to leak ?

​There are many causes of roof leaks. However, the most common reasons include:

• The terrace is open to the public, in direct contact with many water sources such as water from the pipeline system, rain water. Stagnant water on the rooftop may not cause any serious problems in the early days. However, if the water is stagnant for a long time, the terrace surface is likely to peel off. Water seeps through the cement, the terrace floor seeps into the house below, causing the phenomenon of seepage.

• The terrace is not waterproof. Or the waterproofing material is not of good quality.

• The terrace is not properly designed. Common technical errors include: not installing a drainage system, the terrace does not have a standard slope for standing water to flow into the drainage pipe.

• The drainage pipe is blocked due to garbage, mud and has not been cleared for a long time.

• The terrace is degraded because it has been built for a long time. Water seeps through cracks causing seepage.

• Concrete surface foams when it rains.

Benefits of making a roof waterproofing system:

• Extend the life of the terrace: The waterproof layer prevents water from seeping through the cement layer, damaging the architectural structure of the terrace in particular and the house in general.

• Long-term cost savings: The terrace is not waterproofed effectively from the beginning, the cost of repair and restoration when leaking is very high. Therefore, combating the system in the first place will help save costs in the future.

• Improve the aesthetic effect of the building: The waterproof layer is considered as a protective cloak for your house from leaking, moldy and maintaining its beauty over time.

Current effective methods of waterproofing terraces:

• Before implementing waterproofing for the terrace, it is necessary to clean the terrace so that the waterproofing solution penetrates better.

• If the terrace is in the process of construction, it is necessary to clean the mortar and cement to make the concrete surface inert. Grind the surface of the terrace to be waterproof and then use a broom or an industrial vacuum cleaner to clean impurities and dust.

• If the terrace waterproofing has been constructed for a long time, now it is necessary to conduct tiled waterproofing, it is necessary to carry out drilling and perforating the ground above to expose the cement layer. Next perform cleaning as above. If there are large cracks, they should be treated before waterproofing. Possible measures include: use elastic waterproofing agent BS:8620 CT - intoc to handle.

• During construction and after construction, avoid letting rain affect the waterproofing area. Rainwater will make unfinished construction ineffective.
