Illustration of Bathroom Leak Analysis

Toilets are prone to leaks. Over time, with continuous use, domestic water can seep through the toilet floor and internal pipes, accumulating in the sump pit due to inadequate drainage. Once the sump is full, water can easily leak through cracks and along the pipe walls to the lower floor and under the threshold stone, seeping into the living room. The water then spreads everywhere along the cement mortar layer beneath the tiles. Relying solely on the drain in the toilet's tiled surface is insufficient to address internal leaks. Poor waterproofing in the toilet can lead to leaks, which are not only time-consuming but also costly.

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

The toilet sump can be understood as the storage space for water inside a toilet. The toilet combines waterproofing and drainage layers, allowing domestic water to seep through the toilet's decorative layer to the sump. It is then directly drained out through the waterproof and drainage layers and the drain outlet, ensuring a combination of prevention and drainage without water accumulation, thus eliminating the risk of leaks.

Features of Waterproofing for Kitchen, Bathroom, and Balcony

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

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

1. Waterproofing repairs for kitchens, bathrooms, and balconies are challenging and costly post-construction. They require dismantling multiple layers and re-applying waterproofing, which can be 5-10 times the initial investment. Waterproofing is a one-time opportunity; it demands a strong, reliable bond for the waterproofing layer and a sealing layer.
2. Flexible material, overcoming cracks with suppleness.
3. Offers excellent sealing materials that can effectively seal various interfaces like plastic, rebar, concrete, and multiple structures such as pipe ends and right-angled corners.
4. Construction is possible in damp conditions.
5. Waterproofing is a comprehensive engineering system 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 processes of design, material selection, construction, and maintenance. Ensure a stringent design review from the outset, choose appropriate waterproofing materials based on fundamental principles, select professional waterproofing contractors, and execute meticulous construction and management.

Detailed construction drawing of combined waste and exhaust toilet structure

A sunken toilet, also known as a sunken bathroom, refers to a toilet structure that is partially or entirely sunken to a certain height (usually 35-40cm below the corresponding floor) during the main construction. This allows the horizontal drainage pipes of the toilet to be buried within it. The sunken structure is then filled with lightweight materials or precast slabs, and waterproofing and drainage are combined only at the bottom. This ensures that the toilet's leakage flows into the sunken compartment, which is then drained out, preventing any water accumulation in the bathroom. Waterproofing the bathroom walls up to 2.4 meters is not only for防水 purposes but also to block moisture. Most households would have a wardrobe on the other side of the bathroom wall, and waterproofing can prevent moisture from penetrating into the wardrobe, thereby avoiding dampness, mold, and warping. Areas requiring waterproofing include not only the bathroom but also the kitchen and balcony.
