Core specimens are drilled from the concrete structures repaired by silane-type impregnant and flexible polymer modified cementitious coating materials (PCM) after long term exposure to investigate the performance of those repair materials. Physical properties of the materials are measured and instrumental analysis are conducted to observe the condition of cement particles hydration and polymer film formation. Silane-type impregnant still maintains the performance after 20years at the impregnated depth of 2∼10mm, also flexible PCM is more waterproof and water vapor permeable than initial. Adhesive strength of flexible PCM increased to twice the initial value after 5years, and maintains the performance after 20years. Elongation of the flexible PCM increased after 20years although it decreased after 2years. Hydration of cement didn't almost proceed and the polymer film had almost no damages after 20years.
