INLAND INFRASTRUCTURE (A new repair system speci? cally designed to repair corroded seawalls made of concrete or steel sheet pile, both above and below water, uses engineered FRP applications to offer fast, long-lasting and economical repair alternatives. These lightweight, easy-to-install materials ensure port infrastruc- ture projects can be completed on time, within budget and with minimum disruption of ongoing service.

SPiRe is a patented system provides added strength in ad- structural integrity using ? ber reinforced polymer (FRP) dition to an impervious barrier that keeps water and oxygen technology. It can be engineered to almost any thickness away from the original structure material. By eliminating the and strength, as required by the original structure. FRP in? ow of oxygen, the corrosion rate reaches near zero levels. marine pile and sheet pile repair systems can be engi-

This effective solution uses customized, engineered FRP neered to handle any kind of large debris the structure or panels made of lightweight honeycomb 3D fabric layered be- structures may regularly encounter due to ? oods or tidal tween sheets of resin-saturated carbon or glass fabric.
