CASE STUDYBOKEELIA UNDERPINNING & SEAWALL REPAIR

STRUCTURAL SUPPORT SOLUTIONS FOR BOKEELIA RESIDENTSPROJECT INFORMATION

ANALYSIS

Coastal Foundation Solutions was recently contracted to assist a homeowner with a project in Bokeelia, Florida with several needs. A sliding home foundation and failing seawall following Hurricane Ian prompted swift action to provide proper structural support for this waterfront home.

SOLUTION

Working with their selected engineering firm, we determined that underpinning the foundation would be the best course of action for the home. Once contracted we went to work providing a stable foundation for that structure, along with the appropriate course of action to repair the property’s seawall.

RESULT

We installed 4 underpinning piles along with 7 additional extensions to meet proper torque capacities utilizing our specialized equipment. The installation of these piles provided ample support to the foundation, without disruption to the adjacent areas.

Following the underpinning project, we conducted 5 seawall seam repairs utilizing a marine erosion guard system installed over seawall panel joints. This system is comprised of 1 foot wide vinyl sheets attached to the face of the bulkhead wall over the joints, and is installed 12 inches beneath the mudline that in turn extends to an elevation of 1 foot beneath the seawall cap. This prevents future soil washout between the joints, and helps prevent sinkholes from reoccurring. Additionally, we installed 5 seawall filters into the wall to allow water and hydrostatic pressure to escape. This in turn dramatically reduces load and stress on the seawall and prevents further soil loss.
