Today's news shares with you the waterproofing and leak repair methods for roofs, basements, through-wall pipes, and pre-buried pipes.
In roof waterproofing and leak repair projects, the causes of water leakage through the roof panels:
Poor quality precast or cast-in-place reinforced concrete slabs, exhibiting microscopic leakage phenomena.
    2. Roof panels are showing cracks and splits.
    3. Poor adhesion of waterproof coating, bubbles, and damage present.
    4. The waterproof coating lacks sufficient extensibility, leading to tearing as the board surface cracks.
Roof Waterproofing and Leak Repair Measures:
    1. Surface cleaning of the damaged old waterproof layer has been completed, along with thorough removal of all debris and dust. Waterproof coating has been applied.
    2. Completely remove the old waterproofing layer, exposing the roof structure or leveling layer. Implement waterproofing and leak repair measures based on the water leakage conditions of the panel and wall surfaces. Use grouting methods, filling methods, or a combination of both. Seal the cracks and apply waterproof coatings within the area of the leakage.
