Specific Steps for Underground Parking Garage Leak Repair:

The leakage in the underground parking garage must be located by chiseling to find the leakage point and line, and then leak-proofing should be carried out specifically.

2. Leak points and leak lines are sealed using a combination of rigidity and flexibility, expansion and reinforcement, adhering to the principle of external rigidity and internal flexibility. This means that internal sealing must use flexible grouting materials that can be灌浆 (injected), expand, and渗透 (penetrate) in water, while the external sealing employs rigid, high-strength leak-proof agents.

3. Leak-proofing for settlement joints must be carried out within the joints themselves. The combination of rigid and flexible materials, along with expansion reinforcement, creates an excellent 4-layer leak-proofing barrier, with the layers arranged from inner to outer as flexible, rigid, flexible, and rigid, respectively.

4. To address leakage around embedded components, after chiseling to a certain depth, the nano-micro molecule flexible grouting technique is employed for sealing the leaks.

5. Leak-proofing inside pipeline walls; must be filled solid during the sealing process.

6. Leak-proofing in the basement requires internal engineering work; only with a reasonable plan and correct operations can a good effect be achieved.

Two: Utilize waterproofing and leak-proofing techniques to address:

Waterproofing and leakage prevention techniques effectively address issues such as渗漏水 (seepage and leakage), water stopping, and waterproofing repairs in concrete structures at underground engineering sites, including joints, construction joints, deformation joints, honeycomb surfaces, and shrinkage cracks in concrete, with significant effects.

2. The waterproofing and leakage prevention construction method is simple and effective, with compact equipment that is not restricted by the size of the construction site.

Currently, the waterproofing grouting materials and joint sealing materials used in the waterproof and leakage-blocking techniques are at the leading domestic level, with some having reached international standards.

4. In waterproofing and leakage prevention methods, the use of special professional techniques and materials can reinforce concrete joints, particularly for the prevention and sealing of fine cracks that may occur due to the shrinkage of large-scale cast concrete, thereby achieving the purpose of waterproofing and leakage prevention.
