FRP as a Retrofitting Solution for Submerged piles

Submerged piles are often used in river crossings and offshore platforms. The combination of dry-wet cycle results in rapid corrosion of concrete or steel submerged piles. In addition, marine wood borers and ship worms attack timber piles and weaken these structures. Afzir engineers will provide designs for retrofit of submerged piles that enhance axial, flexural and shear capacity of the pile. In all cases, the piles can be strengthened to levels far beyond the original undamaged pile. The sealed engineering drawings and calculations will be provided to the client.
