One of the most common issues with concrete is a process called “spalling.” When a concrete slab is poured it is structurally reinforced by structural steel rebar to support the design load or to form an integral piece of the structure. Spalling is pretty common due to fatigue caused by rusted steel girders embedded to reinforce the concrete. Here in Southwest Florida it is typically caused by moisture intrusion (after all concrete is pourus) causing the rebar to rust. As the steel rebar rusts, it expands. In fact, that expansion is what causes the concrete to crack, because the rebar can expand up to seven times it’s original thickness! Spalling looks terrible, causing cracks in the surface of the concrete, but it’s much worse than that. Those cracks can look somewhat insignificant on the surface, but may be hiding some more serious problems underneath. Spalling causes structural damage to your building to the point where it could actually have your building crumble to the ground if it’s not taken care of. Aside from cracks in the concrete surface, other signs of spalling include, tile that is lifting due to concrete deteriorating; rusty spots on the concrete,

We specialize in concrete restoration which consists of repairing deteriorated concrete and rusted steel reinforcements in order to bring a building back to its original specifications and condition. There’s an entire process to go through to get back to those original specifications. Here are just a few of those steps, so you are aware of them:

1. We will remove the existing concrete
2. The steel rebar will be coated or replaced
3. Replacement of concrete
4. We will remove and replace the expansion joints, properly spacing them so as not to create the same problem in the future.
5. A waterproof membrane is applied
6. The steel bar is mechanically cleaned
7. Repair of post tension cables
8. Corrosion inhibitors are applied
9. Concrete cracks will be routed and sealed.
