Abstract
Reinforcement of structures in high moisture environments is achieved by applying reinforcement layers which include a fabric portion ( ) and an uncured resin portion ( ) where the uncured resin contains a conversion agent and a thickening agent. The uncured reinforcement layer ( ) is cured in place about the structure to form a composite reinforcement shell ( ). The uncured reinforcement layer ( ) is formed from woven or stitched unidirectional fabric. 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 resin dilution and de-lamination during curing of the reinforcement structure. The resin used is non-toxic with respect to aquatic wildlife.
