As the application of innovative technologies in building subsidence repair has made significant progress in recent years, a variety of new technologies and methods have been developed and promoted to address the subsidence of buildings due to changes in geological conditions, construction defects or environmental factors. Here are some of the main innovative technologies and their applications:

1. Geopolymer injection technology

Geopolymer injection is a method of injecting an expansive polymer resin into the foundation, which can effectively compact the foundation and generate upward force, thereby preventing settlement. The technology has the advantages of non-interference repair, fast, environmental protection, no noise and dust, and is suitable for various soil conditions, and the long-term effect is remarkable.

2. MNC settlement repair technology

By injecting special composite slurry with fluidity and permeability, MNC settlement repair technology fills the soil pores and improves the compactness and bearing capacity of the foundation soil. The technology is suitable for a variety of soil, the construction period is short, the impact on the building structure is small, especially suitable for old buildings or places that need quick repair.

3. Micropore treatment technology

By injecting new materials into the foundation, the micro-pore treatment technology improves the soil structure and increases the bearing capacity. The technology does not need to break and shut down, and uses intelligent monitoring equipment to accurately level, which is suitable for medical, new energy vehicles, warehousing and logistics and other industries.

4. SLAB LIFTING technology

SLAB LIFTING is based on deep injection of geopolymer to lift the foundation by injecting a polymer slurry. This technology is especially suitable for foundation settlement repair in dense urban environments, and can quickly locate and deal with settlement problems.

5. Grouting reinforcement technology

Grouting reinforcement technology prevents foundation settlement and pavement cracking by injecting grout through boreholes on the surface.

6. D-InSAR monitoring technology

Differential Synthetic Aperture Radar (D-InSAR) technology is used to monitor the effects of wellbore grouting on surface and building deformation. The research shows that the technology can monitor the small settlement with high precision, which provides a scientific basis for grouting engineering.

7. Environmental protection and pollution-free materials

The use of environmentally friendly and pollution-free polymer composite material for foundation reinforcement avoids the risk of secondary settlement caused by traditional grouting process.

8. Comprehensive tilt correction technology

In some complex foundation settlement projects, the use of low-clearance large-diameter pile rock-socking technology and precise resetting and correction technology can effectively solve the problems of plant tilt and structural displacement.

9. New chemical material technology

New chemical materials technology enables fast, low-cost foundation reinforcement, lifting, and correction.

10. Low-impact development techniques

In urban renewal projects, low-impact development techniques reduce manual intervention through ecological restoration and rain garden design, while solving the problem of foundation settlement.

As it is also known that the application of innovative technologies in building subsidence repair not only improves the efficiency and quality of the repair, but also reduces the environmental impact and damage to building structures. The popularization and application of these technologies provide a variety of feasible solutions to solve complex foundation settlement problems, and have important practical significance and broad application prospects.
