Controlled Slab Lifting in an Active Cool Dock Environment: A 300 LF Joint Realignment Project – Phase 2
by Loral Concrete Slab Solutions
300 LF slab settlement correction — completed overnight.
Last week, we shared a project involving a high-traffic cool dock with:
- 50’ x 70’ slab sections
- 1/8″ – 5/16″ settlement
- Armored joints on both sides
- Hydrogen forklifts and fueling stations (no sparks allowed)
- 12-hour window to complete the repair and return to service
The Result:
The repair was completed as engineered and on schedule.
- Slab successfully lifted and realigned to the pour strip
- Joint stabilized using UTC 3080 stabilizing foam
- Joint filler system maintained and restored between armored joints
- Floor returned to service within the required window
The Approach:
Instead of removal, overlay, or temporary patching, we executed a controlled slab correction:
- Precision slab lifting using polyurethane injection
- Elevation-controlled lift to avoid overcorrection
- Targeted stabilization to support long-term performance
- Joint restoration to maintain durability under forklift traffic
Why It Matters:
This type of repair isn’t about movement—it’s about control.
- Matching elevation without over-lifting
- Stabilizing the slab to prevent recurrence
- Restoring performance without disrupting operations
Most traditional options would have required:
- Major demolition
- Extended downtime
- Or a visible, long-term patch
This approach delivered a clean, controlled correction with minimal disruption.
If you’re dealing with:
- Slab settlement
- Warehouse floor performance issues
- Joint misalignment
Let’s take a look.
