Using high-pressure grouting equipment, grout liquid is injected into each hole individually starting from the bottom. When the adjacent hole begins grouting, maintain the pressure for 3-5 minutes, then stop grouting at the current hole and switch to the adjacent hole.
Grouting reinforcement for buildings is a technique that enhances structural stability by injecting slurry into the foundation or walls. The basic principle is to fill the voids, cracks, or hollows in the foundation or walls with slurry, thereby increasing the strength, compactness, and impermeability of the structure. The grouting materials typically include cement slurry, chemical slurry, or composite slurry. During construction, holes are drilled to inject the slurry into the target area, where it spreads and solidifies under pressure, ultimately forming a solid reinforcement layer. This method is suitable for addressing issues such as building settlement, cracks, and leaks.

Grouting materials are crucial for reinforcing house grouting, with commonly used materials including cement grout, chemical grout, and composite grout. Cement grout is cost-effective and high-strength, suitable for general reinforcement needs; chemical grout (such as epoxy resin) has good fluidity, ideal for small cracks; composite grout combines the benefits of multiple materials, ideal for complex reinforcement scenarios. When selecting grouting materials, consider the reinforcement target, structural characteristics, and construction conditions.

Grouting reinforcement for buildings offers advantages such as flexible construction, significant effects, and wide applicability. It can be carried out without damaging the building structure, making it particularly suitable for the renovation of old houses. Moreover, grouting reinforcement can significantly enhance the strength and stability of the structure, effectively addressing issues like settlement, cracks, and leaks. It has a short construction period, minimal impact on the living environment, and is a method of building reinforcement.

Quality control of grouting reinforcement for buildings is crucial for ensuring the project's effectiveness. A detailed survey must be conducted before construction to determine grouting parameters; during construction, strict control of slurry proportion, grouting pressure, and flow rate is required; after construction, the reinforcement effect should be evaluated through testing methods. Common testing methods include drilling and sampling, ultrasonic testing, and load tests.
