Void Fills
Eliminate Hidden Dangers Beneath Your Property
Voids — hollow spaces that form underground — are one of the most dangerous and common threats to Florida properties. Caused by erosion, water flow, organic decomposition, poor compaction, or shifting soils, these hidden cavities can exist for years without visible signs until a slab suddenly drops, a foundation cracks, or a sinkhole appears.
Polyurethane foam injection is the most effective method for locating and filling sub-surface voids. The expanding foam flows into cavities of all shapes and sizes, filling them completely and curing into a strong, lightweight, waterproof mass that provides permanent structural support.
Why Polyurethane Foam for Void Fills?
Unlike traditional grouting methods that use heavy cement or sand slurries, polyurethane foam is lightweight (2-4 lbs/ft³), expands up to 20x its liquid volume, and cures in minutes. It flows into irregular spaces that gravity-fed slurries simply cannot reach, ensuring complete fill even in complex void networks.
- Complete coverage: Expanding foam fills every pocket and channel
- Lightweight: Won't overload already weakened soil
- Waterproof: Won't wash out during Florida's heavy rains
- Fast cure: Sets in minutes, providing immediate support
- Structural strength: Can support thousands of pounds per square foot
- Minimal disruption: Small injection holes, no excavation required
