Filling Void Under Concrete Slab for Florida Factory
Located in Orlando, Florida, Slab Fix LLC undertook a significant project aimed at rectifying structural issues for a Florida Factory to fill void under concrete slab using a polyurethane injection process. This project centered around Prodalim’s Ocoee facility and involved addressing a critical problem that had the potential to disrupt operations.
The main drain sewer lines at the Ocoee facility suffered a significant rupture, causing the erosion of approximately 20 cubic yards of compacted fill underneath the concrete flooring. To counteract the potential repercussions of this loss of support, Slab Fix LLC was entrusted with devising a suitable remedy.
A Practical Solution by SlabFix
Drawing on their expertise in structural solutions, Slab Fix LLC proposed a pragmatic approach to resolve the issue. The chosen method involved the application of the Strata-Fill™ 24-039 Geotechnical polyurethane by NCFI Polyurethanes, known for its dual-component composition and slow reactivity. This approach allowed for meticulous void filling, restoring stability to the compromised area. The material’s hydrophobic properties and low density of 2 lbs. per cubic foot made it a well-suited choice for this restoration project.
Reflecting on the project, Yasser Krayem, the owner and operator of SlabFix, shared his perspective: “The Prodalim project underscored our commitment to delivering effective solutions in a seamless manner. Collaborating closely with Prodalim USA Inc. and NCFI Polyurethane’s Geotechnical Division demonstrated our dedication to structural stability for our clients using world class products.”
Efficient Execution, Lasting Results
Slab Fix LLC’s execution of the solution demonstrated efficiency and precision. In just two days, the team successfully injected the Strata-Fill™ 24-039 Geotechnical polyurethane to fill void under concrete slab. This methodical process reestablished the lost support, facilitating the installation of new drainpipes without causing any operational disruptions.
The collaborative effort between Slab Fix LLC, NCFI Polyurethanes and Prodalim USA Inc. exemplifies the positive outcomes that can arise from informed and strategic approaches to structural challenges. By identifying suitable materials and employing a meticulous execution process, the project not only resolved the immediate issue but also fortified the facility’s infrastructure for the future. As Prodalim’s operations proceed without interruption, this project stands as a testament to the impact of well-considered solutions in navigating complex structural setbacks.

Frequently Asked Questions
What causes a void under a concrete slab in a Florida factory?
A void under a concrete slab can form when water leaks, broken sewer lines, or soil erosion wash out the supporting fill beneath the floor. Over time, this loss of support can leave the slab unstable and more vulnerable to cracking or settlement.
How do you fill a void under a concrete slab without removing the floor?
One common solution is polyurethane injection. The material is injected beneath the slab, where it expands to fill empty spaces and help restore support without major demolition.
Is polyurethane injection a good option for industrial concrete floors?
Yes. Polyurethane injection is often a strong option for industrial and commercial floors because it can fill voids, stabilize support conditions, and reduce disruption to operations compared with full slab removal.
How long does it take to fill a void under a concrete slab?
The timeline depends on the size of the void, site conditions, and access, but many polyurethane injection projects are completed much faster than traditional excavation-based repairs. This makes it a practical option for facilities that need to limit downtime.
When should a factory call a professional for slab void repair?
A facility should call for an inspection as soon as it notices floor settlement, cracking, soft spots, drainage-related erosion, or signs of underground pipe failure. Early action can help prevent larger structural problems and avoid more expensive repairs later.
