Naples

Helical piles in Naples, Florida

Naples properties sit on sandy Florida soil over limestone. The Florida Geological Survey explains that carbonate rock across the state can dissolve into cavities, and that surface settlement or collapse can follow when a cavity roof gives way.

That is why a geotechnical report or an engineer's review is common before foundation work on suspect sites. Helical piers suit Naples jobs such as lanais, additions, seawall tiebacks, docks and elevated homes because they are installed with hydraulic equipment and torque is logged as each pier goes in. Permits are generally required, so confirm with the local building department.

Costs and what to ask

Residential helical piers commonly run about $1,400 to $3,000 each installed, according to SlabLocal's cost guide, which also notes that excavation can add $200 to $500 per pier. Quotes for Naples projects vary with pier count, depth to bearing soil and site access. See our helical pier cost guide for what drives the total. Questions worth asking any installer:

• Is an engineer designing the piles, and will the plan show the required depth and torque for the Naples site?
• Will the crew log installation torque for every pile and hand over the records?
• What shaft size, helix configuration and galvanizing or coating does the proposal specify?
• Who pulls the Naples permit, and what warranty covers the piles and brackets?
