Florida, along with the Southeast United States, has unique geology that often requires specialized geotechnical engineering services. Our geotechnical engineers and professional geologists understand that you need effective solutions that can balance your time and resource requirements. We offer innovative and practical ideas that address your design concerns and provide you with the reliability and assurance of a solid solution. Questions? Call us and let’s talk about your project.

1.2-Engineering-Subsurface-ConditionsSubsurface Conditions and Subsidence Investigations

Identify subsurface conditions that can impact your project design and evaluate solutions to remediate possible subsidence issues. Our team of Professional Geotechnical Engineers will determine the problem, design a solution, and oversee the remediation, providing full support to you and your project.

Shrink/Swell Clays

These soils act like a sponge when there is a change in their moisture content and have the potential to severely damage even multi-story buildings due to differential foundation movements. We begin by taking samples and determining if the clay is “active.” Based on the propensity for shrink/swell, the amount of material, and its depth, we can recommend excavating and removing the soil or design a foundation to withstand the potential effects of these challenging soils.

Organic-Laden Soils

By identifying how much organic material in a soil is present, we can evaluate the potential for future problems and propose possible remediation solutions. There are several ways organic soils can be dealt with, including shallow polyurethane chemical injection and/or underpinning.

Buried Debris

Concrete pits, buried tanks and other non-organic subsurface materials can be dealt with through excavation or possibly remediation. We’ll determine what hazard the buried debris may present and then provide options to reduce their effects.


Subsidence issues caused by sinkhole activity can be dealt with prior to construction by utilizing methods such as cement based compaction grouting, vibro-floatation, rigid mat foundation designs. For an existing structure, compaction grouting is an effective solution to mitigate raveling and fill void spaces adjacent to and below the structure. We use historical geological data as well as soil borings to explore and characterize the underlying soils.

1.2-Engineering-Geophysical-SurveysGeophysical Surveys

Determine the subsurface features that may affect your project and how to remediate any challenges prior to construction. Geophysical surveys are a foundational element to our service offering and Geohazards delivers cutting edge technology with our advanced ground penetrating radar (GPR), electrical resistivity imaging (ERI) and electromagnetic (EM) equipment. Our experienced team can determine the ideal geophysical method for your project.

Site Assessments

Site assessment surveys are performed as a part of pre-drilling and pre-excavation surveys. Techniques used for characterization of a site include ground penetrating radar, electrical resistivity measurements and electromagnetics. The results define depth to limestone, delineation of clay and sand bodies, areas of debris, former excavation boundaries, and void spaces.

UST Surveys

Electromagnetic and magnetic techniques combined with ground penetrating radar can effectively locate an underground storage tank or confirm the removal of a UST.

Utility Locating

Combining traditional radio frequency utility locating techniques with geophysical techniques including ground penetrating radar and electromagnetics provides a complete picture of active and abandoned utility lines.

Rebar Locating & Concrete Assessment

2-D and 3-D ground penetrating radar surveys to detect rebar, PT cables, conduits and void spaces in and below concrete structures.
