Waterproofing and leak sealing construction is a critical project aimed at solving leakage issues in buildings or other structures. Below is a detailed introduction to waterproofing and leak sealing construction:

I. Pre-construction Preparation

Prior to conducting waterproofing and leakage sealing work, thorough preparation is essential. Firstly, the construction site must be cleared, ensuring the surface is clean, level, free of oil stains and debris. Secondly, inspect the leakage situation to determine the location and cause of the leaks. Select the appropriate waterproofing and leakage sealing materials and tools based on the leakage conditions.

II. Construction Steps

1. Base treatment: Ensure the base is dry, solid, flat, free of oil stains and debris. In case of cracks or indentations, repairs and leveling are required.

2. Waterproofing material application: Apply or lay the selected waterproofing material according to its requirements on the base layer. Ensure even application without any gaps when applying, and a flat, bubble-free surface when laying. For special areas (such as wall corners, pipe surroundings, etc.), reinforce the treatment to ensure the waterproofing material is tightly adhered to the base layer.

3. Additional Layer Application: As required, apply or lay an additional layer on the surface of the waterproofing material to enhance the waterproofing effect.

4. Application of Protective Layer: Apply or lay a protective layer on the surface of waterproofing materials to shield the waterproofing layer from external damage.

Section 3: Construction Precautions

1. Maintain the subgrade dry during construction, avoiding work in damp or waterlogged conditions.

2. Waterproof materials must be installed according to the product manual's instructions to ensure the quality and effectiveness of the installation.

3. Special attention must be given to the treatment of specific areas, such as wall corners and around pipes, to enhance the waterproofing effect.

4. Inspections and acceptance checks must be conducted upon completion of the construction to ensure the waterproofing effect meets requirements.

Section 4: Post-Construction Maintenance

After waterproofing and leak sealing work is completed, regular maintenance and care are required. Regularly inspect the integrity of the waterproof layer and repair any damage promptly. At the same time, keep the sub-base dry and clean to prevent damage to the waterproof layer.

In summary, waterproofing and leakage sealing work must be conducted strictly according to the construction steps and requirements to ensure quality and effectiveness. Additionally, post-construction maintenance and care are crucial, as they can extend the lifespan and performance of the waterproofing layer.
