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

Preparation Before Construction

Prior to waterproofing and leak sealing construction, thorough preparation is required. Firstly, clean the construction site to ensure the surface is clean, flat, free of oil stains and debris. Secondly, inspect the leakage situation to determine the location and cause of the leak. Select the appropriate waterproofing and leak sealing materials and tools based on the leakage condition.

II. Construction Steps

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

2. Waterproofing materials application: Apply or lay the selected waterproofing material according to its requirements on the base layer. Ensure even application with no 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 over the waterproofing material to enhance the waterproofing effect.

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

III. 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 instructions in the product manual to ensure construction quality and effectiveness.

3. Special attention must be given to the treatment of specific areas, such as wall corners and pipe surroundings, 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-sealing work is completed, regular maintenance and care are required. Regularly inspect the integrity of the waterproofing layer and promptly repair any damage. Additionally, keep the subgrade dry and clean to prevent any damage to the waterproofing layer.

In summary, 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.
