Walmart Concrete Lifting & Joint Restoration

Restoring operational safety

 

 

 

 

Our latest commercial project brought the True Level Concrete team to a busy Walmart Supercentre Port Coquitlam, where high-traffic retail aisles were experiencing slab settlement and joint deterioration.

Located in the Cat Food and Home Department aisles, the affected areas had developed uneven surfaces and tripping hazards due to voids beneath the concrete and failing expansion joints. With constant customer traffic and operational demands, the client required a solution that was fast, non-invasive, and allowed the store to remain fully open during repairs.

 

The Issue

  • Sunken and uneven concrete slabs
  • Tripping hazards in high-traffic retail aisles
  • Deteriorated and missing joint filler
  • Cart disruption due to slab “lippage” (height differences)
  • No ability to shut down store operations

 

The Solution

Calling in the True Level Concrete team for precision commercial concrete repair.

To address both structural and safety concerns, our team implemented a combined approach:

  • PolyLevel® Foam Injection to lift, level, and stabilize settled slabs
  • Joint and Crack Restoration to repair and protect expansion joints

This solution eliminated hazards while reinforcing the slab structure—without removing or replacing the concrete.

 

The Concrete Repair Process

Working in an active retail environment required careful coordination and efficiency. Our team worked closely with store management and night crews to prepare each section while maintaining safe, continuous access for customers and staff.

 

Step-by-step:

  1. Assessed affected areas and identified settlement zones
  2. Coordinated with store staff to clear and prepare work zones
  3. Drilled and installed injection ports in targeted slab sections
  4. Injected PolyLevel® beneath slabs to fill voids and lift concrete
  5. Restored 145 linear feet of expansion joints and cracks
  6. Seamlessly patched all injection points and repair areas

 

Installation Conditions

  • Indoor retail environment
  • Continuous adjacent traffic maintained
  • Phased work to ensure safe access at all times

 

Thanks to the rapid curing properties of PolyLevel® and joint materials, the floor was ready for immediate use, allowing uninterrupted store operations.

 

 

Why PolyLevel® Was the Right Solution

  • Expands to fill voids and stabilize weak soils
  • Lifts concrete with precision and control
  • Lightweight and non-invasive (no added structural load)
  • Waterproof and resistant to washout
  • Fast curing — ready for traffic almost immediately

This made it the ideal solution for a live retail environment with zero downtime tolerance.

 

Results

The project successfully restored structural integrity and operational safety without interrupting store activity.

 

Performance Outcomes

  • Slabs lifted and re-leveled to eliminate trip hazards
  • Voids fully filled and subgrade stabilized
  • Joint systems restored for long-term durability
  • Immediate usability post-installation

Operational Impact

  • Zero downtime for store operations
  • Safe, smooth travel for carts and foot traffic
  • Improved long-term performance of slab system

Issues Resolved

  • Uneven concrete surfaces
  • Slab settlement and lippage
  • Joint degradation and material loss
  • Subsurface voids

 

Long-Term Value

This project demonstrates how targeted slab stabilization can:

  • Extend the service life of existing concrete
  • Eliminate safety risks without major disruption
  • Reduce lifecycle costs compared to replacement
  • Maintain operational continuity in commercial environments

The client is now positioned to consider preventative maintenance in other high-traffic zones, leveraging the same non-invasive approach.
