<p>Reinforcement of structures (32) in high moisture environments is achieved by applying reinforcement layers which include a fabric portion (34) and an uncured resin portion (36) where the uncured resin contains a moisture curable silicon-modified poyether resin. The uncured reinforcement layer is cured in place about the structure to form a composite reinforcement shell (32). The uncured reinforcement layer is formed from either dry-woven fabric or woven fabric which is preimpregnated with a cured resin and then coated with the moisture-curable silicon-modified polyether resin. The invention finds particular use in reinforcing bridge supports and pilings which are at least partially submerged in water. Containment layers are used to prevent de-lamination during curing of the reinforcement structure. Use of a containment layer not only prevents de-lamination caused by waves or other turbulent water, but also enhances the underwater curing process.</p> |
