Seawalls Docks Boat Lifts Electrical Commercial Galleries About News CONTACT US Seawall Construction Protect Your Waterfront Property Seawalls are one of the single most expensive aspects of a waterfront property. The seawall must withstand some of the most brutal conditions of any structure built today. Cracking, bowing, or erosion of the ground behind the wall can be signs of trouble. Heavy loads due to high levels of groundwater, violent storms, and marine borers are just a few of the hazards to consider when evaluating a seawall. VIEW OUR SEAWALL GALLERY 1.

The Area’s Leader in Installing the Most Durable Concrete Pre-cast Seawalls Duncan Seawall is the area’s leader in installing the most durable concrete pre-cast seawalls. Our concrete sheet panels are manufactured off-site by a professional concrete fabricator with on-staff engineers to ensure that each panel is constructed using the highest level of quality concrete consistency. The panels are 8” thick, include 5,000 P.S.I. concrete and continuous steel rebar throughout, and are properly cured for approximately six weeks. These specifications provide the strength and stability needed in a superior concrete panel seawall. After installing the concrete panels, Duncan Seawall supports the seawall with a steel reinforced, 5,000 P.S.I 20"x22" concrete cap and tieback system. Each tieback rod consists of a ¾” diameter hot dipped galvanized threaded rod with a 6” x 6” plate bolted to each end, securing the cap to an independent concrete base buried in the yard. Steel rods are not heated or bent in the field due to the reduction of structural integrity induced in the tieback rod. This finished concrete cap is long lasting, aesthetically pleasing, and an added value to your waterfront property.
