Illustration of Bathroom Leak Analysis

Toilets are prone to leaks. Over time, with the use of the toilet, domestic water can seep through the toilet floor and internal pipes, accumulating in the sedimentation pool due to the structure's inability to disperse it promptly. When the sedimentation pool overflows, water easily leaks through cracks and the walls of the pipes,渗漏到楼下 and under the threshold stones at the base of walls, flooding into the living room as it overflows through the cement mortar layer beneath the tiles. Relying solely on the drain in the toilet's tiled surface is insufficient to address internal leaks. If waterproofing in the bathroom is not properly done and leaks occur, it not only wastes time but also money.

The bathroom utilizes a combined waterproofing system featuring both prevention and drainage.

The toilet sump can be understood as a storage space for water inside a bathroom. The bathroom combines waterproofing and drainage layers, allowing domestic water to渗透 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 avoid water accumulation and prevent leakage hazards.

Features of Waterproofing for Kitchen, Bathroom, and Balcony

1. Moisture and humidity can lead to water accumulation at the bottom of the pool.
2. Multiple pipe root nodes, diverse interfaces.
3. Waterproofing treatment for special areas such as阴阳corners, irregular bases, and dead angles can be quite challenging.

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

1. Waterproofing in kitchens, bathrooms, and balconies is difficult to repair later, with high costs. It requires uncovering all structural layers, 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 flexibility.
3. Features excellent matching sealing materials, capable of effectively sealing multiple interfaces such as plastic, rebar, concrete, as well as various structures like pipe ends and internal/external corners.
4. Moisture and humidity are suitable for construction.
5. Waterproofing is a systematic project 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 a thorough design review from the outset, choose appropriate waterproofing materials based on fundamental principles, select professional waterproofing contractors, and execute meticulous construction and management.

Combination Sanitary Drainage Construction Detail Drawing

The sunken toilet, also known as an underground toilet, refers to the construction of the toilet structure with a partial or full下沉 by a certain height (usually 35-40cm from the corresponding floor level) during the main structure construction. This allows the horizontal drainage pipes of the toilet to be buried within. Afterward, lightweight materials are used for backfilling or prefabricated panels are used to create an open space. The sunken structure only requires waterproofing and drainage measures at the bottom. This ensures that any toilet leaks are directed into the sunken compartment, from where they are 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 would place a wardrobe on the opposite side of the toilet wall, and waterproofing can prevent moisture from penetrating the wall and entering the wardrobe, thus preventing the wardrobe from getting damp, moldy, or warped. Areas requiring waterproofing include not only the toilet but also the kitchen and balcony.
