Polyurethane Foam

Poly Foam for Concrete & Soil Stabilization

Structural polyurethane foam (sometimes called polyurethane injection, foam lifting, or poly grouting) is a high-performance material injected into voids beneath concrete or within weak soil to lift, level, seal, and strengthen foundations and slabs.

In Florida’s environment, with shifting soils, high moisture, and frequent settlement of concrete surfaces, Helicon’s polyurethane foam system offers a fast, durable, minimally invasive solution with long-lasting results.

What Is Structural Polyurethane Foam?

Structural polyurethane foam is a two-component resin system that expands and cures into a rigid foam. It is injected in liquid form into voids, cracks, or beneath concrete slabs. As it expands, it fills spaces, compacts loose soil, lifts settled concrete, and creates a solid, supportive base. Once cured, it resists water, decay, and movement, giving foundations permanent reinforcement.

How Helicon’s Poly Foam System Works

  • Small holes are drilled strategically in the concrete slab, foundation, or structure needing stabilization
  • A polyurethane resin/hardener mix is injected under controlled pressure through those ports into voids or weak soil zones
  • The foam expands, filling voids, compacting surrounding soil, and applying gentle lifting forces to level settled concrete
  • The material cures rapidly (often in minutes), stabilizing the slab/foundation almost immediately
  • Drill holes are patched; surface finished so repair is minimally visible

5/5/26 We hired Helicon to lift a small portion of our sagging pool deck and also stabilize some other areas. My foreman Rey and his crew out of Tampa (DJ and Ajay) were very professional and a joy to work with. All the work was prepped and ready for injection when the generator failed. Rey quickly made some calls and set a plan in place. He called in support from a co-worker down south of us who arrived in an hour and they completed the work in no time. I was very impressed with their leadership and team work when completing the job. Truly a joy to see youth so positive and energized about the work they do. They showed a very positive attitude for the company and the work they do. Truly enjoyed the experience. I also would like to give a shout out to the Manny who came up from Cape Coral, Fl to support the team. Great job Helicon. Will highly recommend your services.

We had a great experience with Helicon. We used them to stabilize a wall at a client's house that we were doing a remodel on. They showed up quickly, worked hard to get us scheduled quickly when the client was under a time crunch because the house was pending a sale and then when a problem arose (nothing to do with Helicon) they (this was mostly Andrew, our project manager, who was GREAT and put up with a lot of headache created by things outside of both of our control....but he handled it with professionalism and a great attitude everytime!) accommodated us by basically starting all the paperwork over and moved the date out. We found them to be thorough in their quality control when an irrigation line was broken and they fixed it same day. Overall, I spoke to a few different managers in different departments by the time the project was completed and I found all of them to be professional and capable and I would definitely use them again in the future! From the initial salesman to the engineer to the project managers and on-site foremen (Felix and Rey).......good job Helicon! They are who we will use in the future for this type of project! Thank you from Syrus Construction Group in Apollo Beach, FL.!
