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

I. Pre-Construction Preparation

Before proceeding with waterproofing and leak plugging work, thorough preparation is essential. Firstly, the construction site must be cleared to ensure the work surface is clean, smooth, free of oil stains and debris. Secondly, inspect the leakage situation to determine the location and cause of the leak. Select appropriate waterproofing and leak plugging materials and tools based on the leakage condition.

II. Construction Steps

1. Substrate preparation: Ensure the substrate is dry, firm, 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 sub-base. Ensure even and thorough application; for laying, make sure it's flat and free of bubbles. For special areas (e.g., corners of walls, around pipes), reinforce the treatment to ensure the material adheres closely to the sub-base.

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.

III. Construction Precautions

1. Maintain the subgrade dry during construction and avoid working in damp or waterlogged conditions.

2. Waterproof materials must be installed according to the instructions in the product manual to ensure quality and effectiveness of the application.

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

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

Four: Post-construction maintenance

After waterproofing and leak-plugging construction 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 subgrade dry and clean to avoid damaging the waterproof layer.

Overall, waterproofing and leak 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.
