if found rust in the reinforced concrete structure. below is fix.
The traditional method of concrete repair is to remove the cracked and degraded concrete to a depth of 20 to 30 mm behind the reinforcing bars to fully expose the rusted reinforcement and move the contaminated concrete away from the steel. All corroded material is removed and the steel is either treated or replaced. Concrete repair mortars are then applied to the surface.

問題，公寓管理層說今年修繕大樓外牆等，預算170萬美元，住戶分攤費用，管理費年收入約70萬美元，缺口近百萬美元。這裏不談錢，我發現有幾個工人刨開原本堅如磐石的牆麵，之後又補上，為什麽？
