Evaluating the type and extent of pile damage
Recommending methods and estimated costs of repairing the piles
Repairing the piles using industry standard pile repair methods including:
Concrete crack repairs involve cleaning and surface preparation, application of high-strength epoxies and grout, addition of tensile reinforcement or post-tensioning, routing and corrosion inhibiter injection with sealing to prevent further crack advancement, and localized sectional removal of poor areas to be reformed and new concrete poured in place.
Concrete spall, delamination, and scale repairs are similar to crack repairs, however, they usually require a larger area to be cleaned and chipped out, steel reinforcement added and addition of more repair material.
Steel repairs include proper assessment and cleaning of corroded members to precede the coating of our Hycoat 151 anti corrosive underwater epoxy paint or other approved products. Additional strength stiffeners can also be added and encased within an FRP jacket filled with epoxies and corrosion inhibitors.
Timber repairs include epoxy injection to fill in voids due to corrosion, and then “wrapped” with a synthetic, corrosion resistant jacket.
