Structural concrete restoration consists of repairing deteriorated concrete and rusted reinforcing steel to bring the structure back to its original specifications and condition. Structural damage is often found on elevated slabs and catwalks, decks, and parking areas. In Florida, most structural concrete damage is caused by moisture intrusion resulting in the rebar rusting.

When moisture penetrates the concrete, it causes the rebar to rust. As rebar rusts, it expands up to seven times its original thickness exerting a force of more than 10,000 psi that causes large cracks and spalling concrete. Seemingly insignificant problems on a building’s surface may be outward indications of much more serious problems beneath that can only be determined by a qualified, experienced structural engineer.

Basic Repair Methods:
Removal of existing concrete
Coating the steel rebar
Replacing the concrete
Removal and replacement of expansion joints
Application of waterproofing membrane
Mechanically cleaning the steel rebar
Post-tension cable repair
Application of corrosion inhibitors
Routing and sealing of concrete cracks
Application of decorative coatings
