Full-scope geotechnical & testing services.

Eleven service lines, one firm, one in-house FDOT- and CMEC-accredited lab — from the first boring to the final stamped report.

Engineering & Investigation

Subsurface answers you can build on.

Stamped, defensible engineering — the borings, the analysis, and the Florida P.E. seal.

Materials & Lab Testing

One accredited lab, no shipping delays.

FDOT- and CMEC-accredited testing processed in-house — faster results, full chain of custody.

How it fits together

Which service comes first, and what follows.

Most projects use more than one of these service lines, and the order matters.

Before design. A site usually starts with geotechnical drilling: SPT borings, CPT, rock coring, or direct push with our own rigs. The recovered samples go to our in-house soil testing laboratory, and a Florida-licensed P.E. turns the data into a geotechnical engineering report with allowable bearing capacity, estimated settlement, and a specific foundation engineering recommendation. Buyers, lenders, and developers who need one can run a Phase I environmental site assessment under ASTM E1527-21 alongside it.

When the ground itself is the question. Ground penetrating radar screens a property for anomalies, and a sinkhole investigation confirms or rules them out with SPT borings. If the repair is compaction grouting, sinkhole grouting monitoring gives the owner independent QA: point-by-point logs and post-grout verification borings.

During construction. Construction materials testing covers concrete, asphalt, soils, and aggregate. Concrete and asphalt testing handles cylinder breaks, Superpave, and density coring, and pavement design and evaluation covers FDOT-compliant flexible and rigid pavement design.

FAQ

Florida geotechnical services: common questions

Does FGS do its own drilling and lab testing, or subcontract it?

We do it ourselves. FGS runs its own drilling rigs and crews, processes samples in its own FDOT- and CMEC-accredited laboratory, and every stamped report is reviewed and sealed by a Florida-licensed Professional Engineer. That keeps one chain of custody from the boring log to the final report.

How much does a geotechnical report cost in Florida?

A geotechnical report for a typical Florida single-family home costs $1,500 to $3,500. Commercial projects typically run $5,000 to $20,000 or more, depending on the structure, its loads, and how deep the borings have to go. Our Florida geotechnical report cost guide covers what drives the price.

Do I need a soil test to get a building permit in Florida?

Not always. The Florida Building Code does not automatically require a soil test for a typical single-family home, but any county can ask for one, and commercial work should plan on it. Our guide to soil testing for a building permit in Florida goes county by county.

Which service do I need if I think I have a sinkhole?

Start with a sinkhole investigation. It has two stages: ground penetrating radar screens the property, then SPT borings confirm or rule out what the radar flagged. Insurance claims are handled under Florida Statute 627.707, and the findings come back in a report signed and sealed by a Florida-licensed P.E.

How fast are lab results?

Lab results typically come back in 5 to 7 days. Samples are processed in our own accredited lab in Ocala instead of being shipped out, which is the main reason.

What parts of Florida does FGS serve?

All of it. FGS is based in Ocala and works statewide, with most jobs in Marion, Alachua, Citrus, Sumter, Lake, Hernando, Pasco, Hillsborough, Pinellas, Orange, Polk, Levy, Putnam, and Flagler counties. Mobilization beyond Central Florida is built into the proposal, so you see it before you authorize.
