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

I. Pre-construction Preparation

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

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 and no omissions 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 waterproofing materials to shield the waterproofing layer from external damage.

Section 3: 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 the quality and effectiveness of the installation.

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

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

Section 4: Post-Construction Maintenance

After waterproofing and leak sealing work is completed, regular maintenance and care are required. Regularly check for any damage to the waterproof layer and repair promptly if necessary. At the same time, keep the base dry and clean to prevent damage to the waterproofing.

Overall, waterproofing and leakage prevention construction must be carried out strictly according to the procedures 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.
