Reinforced concrete structures and especially their reinforcing steel is usually suffering from corrosion and damp and they are a worldwide problem that results in economic and utilization issues. Many problems as corrosion and damp can be prevented in the design phase. This can be achieved by isolation of the structures from these sources. The study focuses on the rehabilitation of existing structures damaged by corrosion and damp. A case study is considered for a residential building located in Amman, Jordan. The chosen building is 10 years old, damaged by corrosion and damp which can be seen on the interior and exterior walls, as the corroded steel reinforcement bars are seen after the removal of the concrete cover. This study aims to find an innovative technique that can rehabilitate the building and prevent previously mentioned damage in the future. For this reason, a channel is constructed along the damaged side of the building with two retaining walls to prevent water dissipation into structural elements. The innovative technique is tested by pumping a massive amount of water, and no leaking or seepage is noticed. It is concluded that the technique shows a very effective way to prevent corrosion and damp damage.
