Sustainable Solutions - Composite Sheet Piles

We are a structural fiberglass composite sheet piles manufactured by the pultrusion process and is designed to be able to weather the harsh marine environment. Many traditional methods of building seawalls from wood, steel, and even concrete simply cannot hold up over time.

Marine borers attack and eat the wood, steel will rust and corrode, and concrete will deteriorate over time as the rebar starts to corrode. Strict environmental laws have prohibited the use of chemically treated wood and other solvent based paints or coatings. The shortened life cycle of traditional materials has increased the costs for maintenance and replacement. We do not leach any chemicals making it environmentally safe. We are a cost effective and a long term solution to any waterfront project.

We are the first composite sheet piles to use a special patented urethane injection box. What makes the injection design significant is that it permits resin to be injected through the most dense layers of roving and fabrics. Other injection systems cannot penetrate these reinforcement packages and therefore do not achieve the wet-out necessary to meet the mechanical properties desired.

In addition to working with traditional thermoset resins, it works best with the pure polyurethane family of resins where glass contents are much higher at 76 to 80 percent. Traditional injection systems cannot possibly inject through this high percentage of dense rovings and mats. This allows the system to have properties that are 30% stronger than any other FRP sheet piles on the market. The line of composite sheet piles uses a proprietary non-hybrid Polyurethane resin system that is exclusive to Gulf Synthetics. Compare our Modulus of Elasticity and Tensile strength to other similar profiles and you will see the remarkable difference.
