Pad-mounted transformers can be hazardous if the concrete supporting them starts to fail. We can help!

Our Transformer Pad Repair Services

Keep Your Power Infrastructure Safe, Level, and Reliable

A settled or uneven transformer pad is a potential a liability. When the concrete supporting critical electrical equipment shifts, it can strain conduits, compromise safety, and threaten system reliability. Foam injection concrete lifting offers a fast, non-invasive, and long-lasting solution to stabilize transformer pads without removing or replacing them.

Why Choose Foam Injection for Electrical Transformer Pads

Polyurethane foam injection is a precision method for lifting and leveling sunken concrete. It’s ideal for transformer pads because it minimizes downtime and avoids costly equipment relocation.

  • No Need to Remove Equipment: In most cases, transformers can remain in place during the lift.
  • Fast, Non-Invasive Process: Small injection holes and quick curing mean minimal site disruption.
  • High Load-Bearing Strength: The structural-grade foam provides exceptional support for heavy equipment.
  • Waterproof and Long-Lasting: Foam resists erosion, washout, and freeze-thaw cycles.
  • Cost-Effective Alternative to Replacement: Avoid demolition, concrete hauling, and extended outages.

Our Concrete Repair Process For Pad Mounted Transformers

  1. Assessment: We inspect pad settlement, soil conditions, and access points.
  2. Precision Drilling: Small holes (about the size of a dime) are drilled through the pad.

  3. Foam Injection: Expanding polyurethane foam is injected beneath the slab, filling voids and lifting the pad evenly.

  4. Verification: We confirm elevation and stability using precision leveling equipment.

  5. Completion: Holes are sealed, and the pad is ready for immediate service.

Ideal for Utilities, Municipalities, and Contractors

We work with power companies, co-ops, and facility managers to restore transformer pad stability without service interruptions. Foam injection offers a dependable, engineered solution to extend the life of your infrastructure while reducing maintenance costs.
