    Solution: 

    Hydraulic Jacking + Polyurethane Injection

A large industrial machine shop facility in Burnaby, BC experienced major slab settlement between structural support columns. Over time, the concrete floor had cracked extensively and dropped unevenly—up to 8 inches in certain areas.
The settlement created serious operational concerns inside the active manufacturing facility, including:
• Unsafe floor conditions• Equipment alignment issues• Structural instability beneath the slab• Workflow disruptions
The biggest challenge: operations needed to continue throughout the repair process.

The Challenge

    5,000 sq ft active warehouse

    Heavy machinery bolted directly to the slab

    Severe cracking throughout the floor

    Up to 8” of settlement in localized areas

    Requirement to keep operations running during repairs

Full slab replacement would have required extended shutdowns, equipment removal, and significant production interruption.

The Solution

We developed a phased lifting and stabilization strategy combining:
Hydraulic Jacking + Polyurethane Injection

    A series of 12-inch holes were strategically cored throughout the warehouse slab 

    Hydraulic jacks were installed to assist with lifting in high-load areas

    Multiple injection rigs were used simultaneously to deliver controlled polyurethane expansion and support

This allowed us to:

    Lift the slab evenly despite heavy loads

    Stabilize underlying soils

    Restore structural integrity across the floor

Execution in the Field

Phased Execution

To avoid disrupting operations, the project was completed in 4 stages:

    Work areas were isolated and completed in sequence

    Machinery and equipment were repositioned as required, between phases

    Core drilling completed

    Lifting and stabilization completed

    Reinstatement of cored holes

    Ready for equipment reinstallation

Execution Details

    Controlled lifting using both mechanical jacking and foam expansion

    Continuous monitoring to prevent overstressing cracked slab sections

    Structural voids filled and stabilized during lift

    Final restoration included patching all core locations

The Results

    Up to 8 inches of lift successfully achieved

    Floor lifted/ levelled across entire 15,000 sq ft area

    Machinery reinstalled without alignment issues

    Safe, stable working surface restored

The facility remained operational throughout the repair process while achieving full slab stabilization and elevation correction.

Why This Solution Worked

    Zero Full Shutdown: Operations continued throughout the project

    Phased Execution: Flexible scheduling around production needs

    Heavy Load Capability: Hydraulic jacks supported machinery constraints

    Cost Savings: Avoided full slab replacement

    Minimal Disruption: No major demolition or extended downtime

Project Impact

This project demonstrates how large-scale industrial slab settlement can be corrected without complete floor replacement or operational shutdown. By combining hydraulic lifting with high-density polyurethane injection, we delivered a solution that was fast, precise, cost-effective, and built for long-term performance.
