Commercial Polyurethane Foam Injection for Slab Lifting and Void Fill
High-density polyurethane foam for commercial concrete lifting, subbase void filling, and rapid slab stabilization across Middle Tennessee.
On cost: Commercial foam injection is priced by the area addressed and the volume of material required. Contact us for a site assessment and estimate.
Overview
Commercial Polyurethane Foam Injection
Commercial polyurethane foam injection is the preferred method for lifting settled commercial concrete, filling voids beneath slabs, and stabilizing weak near-surface soils when speed, minimal disruption, and return-to-service time are priorities. The two-component foam expands on injection to fill voids and generate controlled lifting force beneath concrete. It cures to a rigid, load-bearing solid within minutes.
Two-component polyurethane foam is mixed at the injection nozzle and injected through small-diameter holes drilled through the slab. The two components react on contact and expand to many times their original liquid volume. This expansion fills voids beneath the slab and applies controlled upward pressure. The foam is injected in measured increments with surface elevation monitoring between injections.

Installation Process
How we install commercial polyurethane foam injection
Site Assessment and Slab Mapping
We identify all settled sections, tap-test for voids, and map the injection location layout.
Operational Coordination
We plan the injection sequence around facility operations, working section by section to keep most of the facility accessible throughout the day.
Access Hole Drilling
Holes are drilled through the slab at planned injection points, typically five-eighths of an inch.
Foam Injection in Measured Increments
Foam is injected in controlled passes. Slab elevation is checked at the surface between passes. Injection continues until the target elevation is achieved.
Hole Patching and Same-Day Return to Service
Access holes are patched with fast-setting material. Foam-injected areas are ready for forklift, vehicle, and foot traffic within 15 minutes of injection.
The speed of polyurethane foam is its main commercial advantage. Fifteen minutes after we finish, a forklift can drive over the lifted section. No other lifting method gets a warehouse back to operation that quickly.

FAQ
Commercial Polyurethane Foam Injection questions
No. We use high-density polyurethane formulations appropriate for commercial load environments including forklift traffic, vehicle loads, and heavy equipment.
High-density closed-cell polyurethane foam is chemically stable and does not compress, degrade, or absorb water. The material itself is durable for the life of the slab.
Yes. The injection equipment is compact and the access holes are small, which means foam injection can be performed in low-clearance environments.
More Solutions
Other solutions we offer
Commercial Carbon Fiber Wall Reinforcement
Commercial carbon fiber wall reinforcement applies high-tensile-strength carbon fiber straps bonded to the interior face of a bowing or deflecting wall, creating a rigid stabilization system that transfers lateral load to the floor slab and structural framing above. No yard excavation is required, and installation can be completed around active building operations.
Commercial Helical Piers
Commercial helical piers are engineered steel shaft and plate systems that transfer structural load from weak surface soils to competent load-bearing material at depth. Unlike concrete foundations that require excavation and cure time, helical piers are installed with minimal site disturbance, provide immediate load capacity verified by torque correlation, and can be installed in virtually any weather conditions.
Commercial Slab Lifting and Leveling
Commercial slab lifting restores settled concrete to its original elevation by injecting expanding material beneath the slab through small-diameter access holes. No demolition, no removal of the existing concrete, no extended facility downtime. Ground Up Foundation Repair uses high-density polyurethane foam for most commercial slab lifting applications, because it expands quickly to fill voids and lift slabs, adds minimal weight to the subbase, and cures within minutes.
Pre-Construction Pier Systems
Pre-construction pier systems install engineered helical pier foundations beneath new construction footings before concrete is poured. By anchoring the foundation to competent load-bearing soil or bedrock at depth, pre-construction piers eliminate the settlement risk that standard shallow footings face in Middle Tennessee's variable clay and limestone terrain.
Agricultural Soil Stabilization
Agricultural soil stabilization addresses the weak or compressible subsoil conditions that cause foundation settlement beneath grain bins, farm buildings, and rural structures in Middle Tennessee. Rather than excavating and replacing poor subsoil, stabilization injects or introduces binding material into the soil in place, improving its load-bearing capacity and reducing its susceptibility to moisture-driven settlement.
