The bathroom or kitchen is an indispensable part of our home life, and it's also a place where we use a lot of water daily. Therefore, it's crucial to pay attention to it during construction or decoration to prevent issues like leaks and seepage. Recently, a friend in Dalingshan, Dongguan encountered such a problem; their bathroom leak caused mold on the wall edges, even affecting the hallway and the floors below, causing inconvenience to neighbors. Not knowing what to do, today, Dongguan's Waterproofing and Leak Repair Company shares some relevant knowledge and information on waterproofing and leak repair.

Back to the topic, we continue to introduce the waterproofing and leak repair process. The waterproofing process in the bathroom varies depending on different waterproofing methods, such as tile removal and non-tile removal methods, etc. The process also differs. There are mainly the following steps:

Step: Remove the floor tiles at the leaking area (the tiles may not need to be removed if a non-breaking method is employed)

If it's a building for Lai Jiu Housing, the era remains, generally, it's necessary to remove the tiles and redo the waterproofing for better effect. For new houses, you can permanently scrape off the floor tiles with a trowel, or opt for a non-destructive tile waterproofing method.

Step 2: Drain off wastewater and adjust pipe levels

Then, after the water and electricity installation and decoration are completed, the sewage pipes need to be blocked. For small and medium-sized pipes, use nuts for effective leakage prevention. For large and medium-sized sewage pipes, employ PVC shrink wrap to prevent blockages.

Three Steps: Leveling Floors and Walls to Address Issues

The floor and walls utilize oil-based mortar for a smooth finish. The ratio of concrete to gravel is between 1:2.5 to 1:3, but the floor thickness should not exceed 5cm, and the deviation between horizontal and vertical levels should not be more than 5mm.

Four Steps: Achieving Ground Waterproofing

When applying ground waterproofing, use concrete to block water leakage treatment. Evenly wipe twice at the root of the pipelines. For areas prone to water seepage such as deodorant floors and diagonal lines, vertically apply each brush, creating a protective layer thickness, and conduct a dense water test after moisture-proofing and drying.

During the coating process, it is crucial to prioritize the application of waterproofing in areas prone to leakage, such as the ground traps, pipe roots, wall bases, and corners. These areas should be coated first with the utmost importance. Other areas should be coated on the building facade before the horizontal surfaces. The wall in the shower area should be coated up to 180 centimeters, and the bathtub area should be coated up to 30 centimeters above the bathtub. All waterproof coatings should be applied according to standard procedures, with no omissions, secure adhesion, and without cracks, bubbles, or any other issues.

Five Steps: Irrigation Experiment

During the water immersion test, the container must be filled with water, ensuring that the water depth is no less than 20mm at the deepest level. The ratio of water length to width should be adjusted between 35-40mm. The storage duration should be 24 hours. If there is no significant drop, the waterproofing on the ground will meet the standard. Otherwise, additional moisture protection measures must be taken until the standard is achieved.
