Illustration of Bathroom Leak Analysis

Toilets are prone to leaks. Over time, with regular use, domestic water can seep through the toilet floor and internal pipes, accumulating in the sump chamber if not drained promptly. Once the sump is full, water can easily leak through cracks and pipe walls to the lower level, as well as seep beneath the threshold stone and into the living room. It will then overflow through the cement mortar layer under the tiles, resulting in water everywhere. Relying solely on the drain in the toilet's tiled area won't solve internal leakage issues. If the waterproofing in the toilet is not done properly and leaks occur, it will not only take a lot of time but also cost a lot of money.

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

The toilet sump can be understood as the water storage space within a bathroom. The bathroom combines the waterproofing layer with the drainage layer, allowing domestic water to seep through the bathroom's decorative layer 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 water accumulation and eliminate leakage risks.

Features of Waterproofing for Kitchen, Bathroom, and Balcony

Moisture and humidity can lead to water accumulation at the bottom of the sedimentation pond.
2. Many pipe root nodes, diverse interfaces.
3. Waterproofing treatment for odd-shaped corners, irregular bases, blind spots, and other special areas can be quite challenging.

Principles for Waterproofing Materials 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; it demands a strong and reliable bond for the waterproofing layer and a sealing layer.
2. Flexible material, conquer cracks with suppleness.
3. Offers excellent matching sealing materials, capable of effectively sealing multiple interfaces such as plastic, steel rebars, concrete, as well as various structures like pipe ends and inside and outside corners.
4. Construction is possible in humid conditions.
5. Waterproofing is a systematic engineering project, requiring 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 well-designed approach 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 Sanitary Prevention and Drainage Structure

The sunken bathroom, also known as a下沉式卫生间, refers to a bathroom structure where the floor is partially or entirely 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 bathroom to be buried within, and then filled with lightweight materials or supported by prefabricated panels. The sunken structure only requires waterproofing and drainage at the bottom. This design ensures that any leakage in the bathroom flows into the sunken compartment, which then drains out through the compartment's drainage outlet, preventing water accumulation in the bathroom. Waterproofing the bathroom walls up to 2.4 meters high is not only for waterproofing purposes but also to block moisture. Most households place a wardrobe on the opposite wall of the bathroom, and waterproofing can prevent 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.
