Introduction
Concrete slabs play a vital role in modern construction, serving as the foundation for homes, industrial facilities, public buildings, and critical infrastructure. Yet, slabs are vulnerable to soil settlement, erosion, and voids beneath their surface. Left untreated, these problems can lead to uneven floors, cracking, structural instability, and even safety hazards.
Traditionally, the solution was to remove and replace the slab entirely—a costly, time-consuming, and wasteful process. Today, advanced concrete slab lifting techniques provide a faster, safer, and more eco-friendly alternative.
As a global leader in foundation subsidence treatment and soil stabilization, Hengxiang Hongye has dedicated itself to research and technological innovation in ground improvement. Our mission is to deliver cutting-edge solutions that restore stability and extend the service life of residential, industrial, and public structures.

Understanding Concrete Slab Settlement
Concrete slabs may sink or tilt for various reasons:
-
Weak or compressible soils unable to support the weight of the structure.
-
Groundwater changes that wash away fine soil particles.
-
Poor compaction during original construction.
-
Seasonal variations causing soil shrinkage and swelling.
These conditions create voids beneath the slab, leading to settlement, cracking, and uneven surfaces. The risks include:
-
Tripping hazards in public and residential areas.
-
Damage to machinery and vehicles in industrial settings.
-
Structural misalignment in buildings, affecting walls, doors, and windows.
Hengxiang Hongye’s Advanced Slab Lifting Techniques
Unlike traditional replacement, slab lifting restores the original level of concrete slabs by reinforcing the soil beneath. Hengxiang Hongye integrates non-destructive, controllable, and eco-friendly technologies that minimize disruption and maximize safety.
1. Precision Injection Grouting
-
How it works: Specialized grouts are injected into weak soils under controlled pressure.
-
Function: Fills voids, compacts loose soils, and lifts slabs evenly.
-
Advantages: Non-invasive, fast application, long-lasting stabilization.
2. Expanding Resin Injection
-
How it works: Lightweight resins expand on contact, lifting slabs gently.
-
Function: Ideal for small settlements and interior floor leveling.
-
Advantages: Minimal drilling, rapid curing, immediate usability.
3. Layered Soil Reinforcement
-
How it works: Strengthens shallow and dee
