Practice Areas
Here you will find an overview of the geological expertise we offer.
Sinkhole Activity and Subsidence Risk
Britannia Solutions LLC is a recognized expert in Florida’s sinkholes, sinkhole activity and the mechanisms and processes that lead to property damage due to ground movement. We also have experience of other ground subsidence and/or ground movement issues related to problematic soil conditions (such as organics, debris/fill, clay soils, etc.), groundwater, underground structures, mineworkings and mineshafts. If the ground is a problem, we can find out why.
Ground Investigation and Ground Risk Management
It is essential to understand the risks that the ground and groundwater conditions at a property can pose before embarking upon any development or construction project. Costs associated with unforeseen ground conditions during construction can exceed the price of a ground investigation by several orders of magnitude. Through sister company IDGS, LLC, we own and operate drilling and testing equipment. We can help!
