Seawall Repair Siesta Key

Many of us love living close to the water, but when we need distance and protection from the powerful forces of water, Siesta Key turns to Helical Foundations to keep us safe and our homes, businesses and communities sustainable. Helical Foundations is your expert in seawall repair and replacement. Everything we do is designed for our changing environment.

Siesta Key can face tough storms, hot temperatures, humid conditions and coastal erosion. These processes can eat away at land until the waves are lapping up against the foundation of your home or business. Water can seriously degrade and weaken concrete, causing it to crack and crumble. Erosion can also lead to leakage and water pooling in and around your structures.

The cost of a seawall repair is far less than the destruction of your home or business. The longer you put off building a seawall or disregarding repairs to your existing seawall, the worse the damage will become. You need a seawall repair company that understands Siesta Key’s climate and conditions.

Helical Foundations is a design/build contractor specializing in the installation of seawalls in consideration of site-specific conditions and concerns. Our process begins with determining your needs, providing a design by a FL licensed structural engineer, obtaining the necessary permits, and installing the design to specifications and code. Our goal is to provide shoreline protection and aesthetic features to your complete satisfaction.

Signs That You May Need a New Seawall:

warning icon
Multiple cracks in the seawall cap and/or spalled concrete areas with exposed rebar
warning icon
Erosion holes on the landward side of the seawall
warning icon
The seawall cap is no longer straight and bows outward
warning icon
The bottom of the seawall panels are toed outward

We understand how to interpret these conditions, determine the necessary scope of work and provide a comprehensive repair or replacement from diagnosis to completion. We are very sensitive to the concerns of our customers and develop the best solution that fits their needs while maintaining quality, strength and the aesthetic.


Sample Client Project


Helical Tiebacks can be utilized for new seawalls or repairing existing seawalls. Helical Tiebacks provide superior strength and adaptability for anchoring and reinforcing new and existing seawalls where concrete deadmen are failing or not feasible. Tie backs can be installed on a batter (angle) to navigate around existing structures such as pools and building foundations and the installation process minimizes any damage created to lawns or gardens. A sacrificial anode can be incorporated into the installation to provide additional life to the piling system.

Helical Anchors are excellent solutions for moorings and pilings especially in sensitive environments where disruption of the seabed must be minimized. Each anchor can be designed to adapt to existing conditions and can be fabricated to extend anchor life from corrosion.


  • Can be installed beneath existing structures
  • Can be installed in limited-access areas
  • Can be designed site specific for existing conditions and intended loads
  • Can be proof-tested and immediately loaded
  • Can be easily and quickly removed, if necessary
  • Life span can be increased indefinitely with a sacrificial anode
  • No impact to the environment or surrounding area

This picture shows an effort by the owner to stop the outward rotation of the bottom of the seawall panels with the wood pilings.
seawall tiebacks failure
This picture shows failure of the tiebacks, concrete seawall cap and concrete seawall panels. The top of the wall is rotating outward indicating the tiebacks have failed. The concrete cap at the bottom left of the image has started to break apart. Tapping on the top of the slab above the seawall cap indicates a void exists which is probably due to the migration of soils through the concrete seawall panels, meaning the panels are failing.
