The corrosion of the reinforcing steel and the use of de-icing salts are the worst enemies of concrete staircases and balconies. These two factors alone can cause the shattering and delamination of your concrete.
To make lasting repairs, you should sound the concrete with a hammer and remove the brittle parts until the concrete is solid.
The reinforcing steel should also be stripped and treated with an anti-corrosive agent. Depending on the situations encountered, you’ll sometimes have to add anchors to connect the old concrete to the new.
Our specialists at Restaure-Action will use the right repair mortar from among the multitude of mortars available on the market.
