Illustration of Bathroom Leakage Analysis

The bathroom is a place prone to leaks. Over time, with prolonged use, domestic water can seep through the bathroom floor and internal pipes, accumulating in the sedimentation tank. If not drained promptly, the sedimentation tank can fill up, and water can easily leak through cracks in the pipes,渗 into the floor below, and seep past the threshold stone under the walls and into the living room. The water will then overflow through the cement mortar layer under the tiles, causing widespread flooding. Relying solely on the drain in the bathroom tiled area is insufficient to address internal leaks. If the bathroom waterproofing is not done properly and leaks occur, it will not only take time but also cost more money.

The bathroom features a waterproofing system that combines prevention and drainage.

The toilet sump can be understood as a storage space for water inside a bathroom. The bathroom combines a waterproofing layer with a 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, preventing water accumulation and eliminating leakage risks.

Features of waterproofing for kitchen, bathroom, and balcony

1. Moisture and humidity; prone to accumulating water at the bottom of the sediment pond.
2. Many pipeline root nodes, diverse interfaces.
3. Waterproofing treatments for odd-shaped corners, irregular bases, blind spots, and other special areas are more challenging.

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

1. Waterproofing in kitchens, bathrooms, and balconies is challenging to repair later on, 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; it demands a strong and reliable bond for the waterproofing layer and a sealing layer.
2. Flexible material, bending without breaking.
3. Features excellent matching sealing materials that can effectively seal multiple interfaces such as plastic, rebar, and concrete, as well as various structures like pipe ends and right-angled corners.
4. Construction is possible in humid conditions.
5. Waterproofing is a comprehensive engineering system that requires close collaboration between engineering management and materials engineering. Neglecting any aspect can lead to failure in waterproofing. Therefore, it is crucial to coordinate the design, material selection, construction, and maintenance processes. Ensure a rigorous design review from the outset, select appropriate waterproofing materials based on fundamental principles, choose a professional waterproofing contractor, and execute meticulous construction and management.

A sump toilet, also known as a sunken toilet, refers to a bathroom design where the structural layer is partially or fully sunken to a certain height (usually 35-40cm below the corresponding floor level) during the main construction. This allows the horizontal drainage pipes of the toilet to be buried within, followed by backfilling with lightweight materials or the use of prefabricated panels. The sump structure only requires waterproofing at the bottom. This design ensures that any leaks in the toilet drain into the sump, then out through the drainage outlet, preventing water accumulation in the bathroom. Waterproofing the bathroom walls to a height of 2.4 meters is not only for防水 purposes but also to block moisture. Most families place wardrobes on the opposite wall of the bathroom, and waterproofing prevents moisture from渗透 into the wardrobe, thus preventing dampness, mold, and deformation. Areas requiring waterproofing include not only the bathroom but also the kitchen and balcony.
