Industrial concrete slabs are critical infrastructure in logistics platforms, production areas, and heavy-duty service yards. However, over time, these slabs can show signs of deterioration: settlement of isolated panels, edge spalling, slab rocking (pumping effect), or visible Cracks in walls along construction joints. These pathologies often indicate a deeper issue—Subsidence of the supporting ground layer.
At GEOSEC, we address these challenges through a specialized intervention technique: Resin injections. This method enables fast, clean, and non-intrusive stabilization of sub-base soils without interrupting ongoing operations, even in active warehouses or heavy vehicle circulation zones.
Why Do Industrial Slabs Settle?
Industrial slabs are subjected to repetitive dynamic loads from forklifts, trucks, or pallet jacks. If the underlying base or sub-base loses density or suffers washout due to water ingress—often through cracked joints or poor drainage—the resulting voids lead to differential settlements. In turn, the slab loses uniform support, resulting in cracking, joint misalignment, and increased wear and tear.
The causes of Subsidence may include:
• Loss of support due to erosion or washout
• Poor compaction during original construction
• Excessive moisture prior to concrete pouring
• Long-term fatigue under heavy loads
Expanding resin injection: A Precise and Controlled Solution
GEOSEC employs the patented Soil Stabilization™ and See&Shoot® technologies to restore bearing capacity below affected slabs. Through a grid of 8–12 mm injection holes, our teams introduce MAXIMA® Expanding resin, which reacts chemically to expand, fill voids, and compact the surrounding soil.
The process is monitored in real time using laser level receivers with 0.1 mm precision, ensuring vertical lift—only if required—occurs uniformly and predictably. In cases where joint misalignment causes slab rocking, injections are carefully positioned along both sides of the joint to rebalance the load transfer and eliminate differential movement.
Case Study: Heavy-Duty Logistics Platform
In a 32,000 m² logistics hub GEOSEC intervened on deteriorated slabs used for continuous truck traffic. The external pavement, exposed to weather and daily vehicle load, had developed visible Cracks in walls and joint degradation due to subgrade Subsidence. Our Resin injection method restored ground contact, filled eroded zones, and stabilized over 750 meters of affected joints—without halting operations.
This approach not only improved structural stability but also extended the slab’s lifespan and restored safe rolling conditions for vehicles.
