Causes of Concrete Ceiling Leakage

Concrete ceiling leakage can be caused by a variety of factors, including:

  • Use of poor quality materials during construction, leading to deterioration over time
  • Inadequate structural integrity, such as improper steel mesh and low-quality concrete
  • Poor drainage systems in households with terraces, resulting in water accumulation
  • Inadequate or improper application of waterproofing measures during construction

Methods to Waterproof the Concrete Ceiling

Using Asphalt

Asphalt is a highly adhesive and elastic material that can effectively repair cracks in the ceiling. The process of using asphalt for waterproofing includes:

  1. Clean the ceiling and apply a layer of asphalt primer.
  2. Apply the asphalt to the ceiling, ensuring proper adhesion and removing air pockets.
  3. Test the effectiveness of the waterproofing by spraying water on the treated surfaces.
  4. Apply a layer of cement on top for additional waterproofing.

Using Sika

Sika is a liquid waterproofing product that forms an effective membrane. The process of using Sika for waterproofing includes:

  1. Pour Sika into cracks and grooves on the ceiling.
  2. Apply layers of Sika waterproofing and allow them to dry.
  3. Test the effectiveness of the waterproofing by applying water to the treated areas.

Using Hot Melting Method

The hot melting method is a highly effective and non-toxic way to waterproof the ceiling. The process includes:

  1. Clean the ceiling thoroughly.
  2. Measure and cut the waterproof membrane, overlapping the edges.
  3. Apply a layer of bitumen primer on the surface.
  4. Use a gas blowtorch to heat and melt the membrane.
  5. Check the treated area for any leakage after 24 hours.
