Illustration of Bathroom Leak Analysis

The bathroom is a place prone to leaks. Over time, with the use of the bathroom, domestic water can seep through the floor layer and internal pipes, accumulating in the sump pit instead of being drained away. Once the sump is full, water can easily leak through cracks and the walls of the pipes, seeping down to the floor below and渗透 into the living room under the door threshold. The water then spreads everywhere along the cement mortar layer beneath the tiles. Relying solely on the drain in the bathroom's tiled surface is insufficient to address internal leaks. If the waterproofing in the bathroom is not properly done and leaks occur, it not only takes time but also costs money.

The bathroom employs a waterproofing method that combines prevention and drainage.

The toilet sump can be understood as a storage space for water inside a bathroom. The bathroom combines the waterproofing layer with the drainage layer, allowing domestic water to seep through the decorative layer of the bathroom floor into the sump. It is then directly drained out through the waterproof and drainage layer and the drain outlet, combining prevention and drainage to prevent waterlogging and eliminating the risk of leakage.

Features of Waterproofing for Kitchen, Bathroom, and Balcony

1. Moisture and humidity; water tends to accumulate at the bottom of the sediment pond.
2. Many pipe root nodes, diverse interfaces.
3. Waterproofing treatment for irregular angles, uneven bases, blind corners, and other special locations is more challenging.

Principles for Waterproofing Materials Selection in Kitchen, Bathroom, and Balconies

1. Waterproofing in kitchens, bathrooms, and balconies is challenging for later repairs, costly, and requires uncovering all structural layers. It involves redoing the waterproofing and then restoring them, with repair costs being 5-10 times the initial investment. Waterproofing is a one-time opportunity; the waterproofing layer must be firmly bonded and reliable, with a sealing layer.
2. Flexible material, overcoming cracks with suppleness.
3. Features excellent matching sealing materials, capable of effectively sealing multiple interfaces such as plastic, rebar, concrete, and various structures like pipe ends and internal/external corners.
4. Moisture and humidity are suitable for construction.
5. Waterproofing is a systematic engineering that requires close collaboration between engineering management and materials engineering. Neglecting any stage can lead to failure in waterproofing. Therefore, it is crucial to coordinate the design, material selection, construction, and maintenance processes. Ensure the design is approved from the outset, choose appropriate waterproofing materials based on fundamental principles, select a professional waterproofing contractor, and execute meticulous construction and management.

Toilet combination prevention and drainage structure detail drawing

The sunken toilet, also known as an underground toilet, refers to the construction of the toilet structure at a certain height (usually 35-40cm below the corresponding floor level) during the main building phase. This allows the horizontal drainage pipes of the toilet to be embedded within. The void is then filled with lightweight materials or precast slabs suspended, and the sunken structure only requires waterproofing and drainage measures at the bottom. This ensures that any toilet leaks are directed into the sunken chamber, which is then drained out, preventing water accumulation in the toilet. Waterproofing the toilet walls up to 2.4 meters is not only for防水 purposes but also to block moisture. Most households place wardrobes on the opposite side of the toilet wall, and waterproofing can prevent moisture from seeping into the wardrobe, thus avoiding dampness, mold, and deformation. Areas requiring waterproofing include not only the toilet but also the kitchen and balcony.
