When holes, depressions, dead spots, or cracks appear in the roadway, or if you find very soft soil or soil erosion on the ground surface, these could be signs of sinkhole activity requiring soil stabilization. Many locations in Florida’s sub-structure contains geologically weak limestone. Natural elements from rain and other ground water finds its way to the limestone eroding the sub-structure. Also, heavy rainfalls eat away at the shifty lime-based Florida soils.

Areas around stormwater drains are prime locations for sinkholes to occur. All the water from rain, runoff, leaks, and other sources gathers at the drain, saturating the surrounding soil. If the earth around the stormwater drains sinks, the stormwater drainpipe can shift, breaking joints or causing the drainpipe and structures to crack and creating a conduit for soil erosion and eventually sinkholes. Flotech has prevented the collapse of over two hundred sinkholes in Right of Way locations by filling subterranean voids with Compaction Grouting.

Flotech personnel are trained and experienced in chemical grouting for sinkhole stabilization, sealing of sewer pipes, and structures. We are an authorized installer for the leading chemical grout manufacturers. The company also has a large fleet of sealing and testing trucks available to support clients on a regularly scheduled or emergency basis.
