Located a short ride from Naples and close to the Everglades is Marco Island, the largest island in Florida’s Ten Thousand Islands. The tropical climate of Marco Island offers a significant attraction to the seaside area, with the water being the next major enticement. The island has a continual array of home construction and remodeling projects due to its tropical attraction.
The owners of an older home elected to give their home the face lift it craves by rejuvenating its structural integrity and curbside appeal. The finished product of a newly remodeled home allows the quality to shine but also makes you thrilled, once again, about arriving home.
Due to the unknown soil conditions and limited equipment access Alex of Alex Parker builders provided us with the direction to install helical piles. Helical piles were preferred because of their load capacities, cost savings, and their ability to provide piling information for each pile based on installation torque.
Coastal Foundation Solutions was contracted to provide additional engineering and expertise for the remodeling foundation project. We determined that our deep helical pile foundation system would have to be securely drilled into the subsurface soil to reinforce the proposed new home concrete footers.
A helical pile configuration consisting of a 2-7/8 inch outside diameter round shaft with an 10″-12″-14” triple-helix lead section was selected. The piles were installed with a drive head attached to a Caterpillar 305 CR mini excavator and were installed to a minimum of 3,100 foot/pounds torque. Each helical pile was advanced to a depth of 28 foot below grade. Every pile was attached to the footing with a new galvanized construction bracket. The ultimate capacity of the helical pile was 15.5 tons.
