SPRING HILL - A sinkhole opened between two homes on Lynnhaven Road in Spring Hill on Thursday and crews were working to fill it back in.
The sinkhole was about 40 feet in diameter and 15 to 20 feet deep, said Taylor Yarkosky, owner of Advanced Pier Technology. The company was at the home pumping a concrete mixture into the ground to fix some existing sinkhole activity about noon on Thursday when the ground gave way between the homes in the 10000 block of Lynnhaven Road, Yarkosky said.
"They were pumping and all the sudden the ground just started falling in and it opened up quick," Yarkosky said. "They're just now hoping that it doesn't spread any further or open any further. That's their biggest concern I'm sure at this point."
By 5 p.m. Advanced Pier Technology was using a backhoe to fill in the sinkhole.
Because the sinkhole may encroach on right of way, the county was sending an employee from its public works department to investigate. The county will only get involved if the sinkhole is threatening public safety.
No evacuations were needed and no roads were closed, the Heranando County Sheriff's Office said.
The homeowner near the sinkhole had filed a claim with Citizens Insurance, and Advance Pier Technology was working under the direction of a geological engineer to mitigate any sinkhole activity, Yarkosky said.
Crews drilled holes up to 70 feet deep in the soil under the home to the lime rock and were pumping concrete into those holes, he said.
It's not uncommon for the ground to give way during the procedure because the concrete is being pumped under pressure into soil that is already unsteady, Yarkosky said.
"Nobody got hurt thank goodness," he said.
