Subsurface Evaluation & Geotechnical Engineering
We provide geotechnical investigations, foundation engineering, sinkhole and karst evaluations, and ground improvement solutions for residential, commercial, industrial, and public-sector projects throughout Sarasota County, Siesta Key, Longboat Key, and the surrounding coastal areas.
With extensive experience across coastal barrier islands, inland neighborhoods, high-water-table zones, and reclaimed land, our team brings deep local geology knowledge and proven engineering practice to every Sarasota project.

Why Geotechnical Engineering Matters in Sarasota
Sarasota subsurface conditions are highly variable: shallow limestone, coastal sand profiles, fill soils, organics, tidal groundwater, and known karst features all impact structural performance. Proper investigation is critical to avoid settlement, differential movement, and moisture-related failures.
What the investigation protects
- Identify site-specific risks: organics, loose sands, voids, SHWT, soft strata.
- Engineer foundations tailored to Sarasota coastal and inland soil behavior.
- Reduce structural risk and avoid costly redesigns or delays during permitting.
- Ensure long-term performance for homes, commercial sites, and waterfront structures.

Sarasota Geotechnical FAQs
Do Sarasota coastal soils require special foundations?
Yes. Coastal sands, shallow limestone, and fluctuating groundwater often require deep foundations, soil improvement, or engineered slabs.
How early should a geotechnical engineer be involved?
Before design and permitting, especially for coastal work, additions, pools, or any site with unknown fill or organic layers.
Is Sarasota prone to sinkholes?
Sarasota lies within the Florida karst region. While not as active as Hernando or Pasco, voids and solution cavities do occur, especially east of I-75.
