Common Reasons Why Concrete Requires Repair

Concrete is widely used for everything from foundations to bridges. Water tanks, buildings, and even dams can be made with concrete. It’s a strong, durable, and well understood material. But that doesn’t mean it’s going to last forever without a bit of attention and sometimes repair. In fact, concrete today isn’t even the same as the concrete that was poured for your commercial parking garage twenty years ago. Below are some of the most common reasons that concrete requires repair.

Rebar Corrosion

Concrete is often reinforced with steel rebar. The rebar is meant to help keep the concrete from crumbling. Unfortunately, the opposite seems to be the real problem. If rebar is exposed to excess carbon chlorides or dioxide, it will begin to corrode, causing the concrete around it to crumble too. Rust can burst concrete.

Alkali-Silika Reactions (ASR)

This is a serious problem for some concrete structures that were built before the reaction was well understood. ASR is a reaction within the concrete due to the chemical make-up of some aggregates. Alkaline cement will react with water, form a gel, and then cause cracks in the concrete.

Abrasion

Water will wear away at concrete over time, which is commonly seen in pipes. Abrasion can also be due to physical wear from items such as forklifts.

Freeze-Thaw Repair

Air-entrainment and unprotected concrete or protective coating on concrete can wear off and concrete can become saturated with water, which then expands when it freezes. It then breaks down into its stone sand and cement Fortunately, it is possible to repair concrete that is showing signs of any of these problems. But with Foundation Pros concrete repair team, you can often avoid a complete tear down. Most importantly, the cause of the deterioration should be identified so that the concrete repairs last and the problem doesn’t reoccur.

Reasons for Concrete Restoration

Some of the reasons that concrete in a parking garage or structure needs to be restored have to do with water. Water can leak through cracks or failed joints. Water can also contain corrosive substances and chlorides that breakdown concrete or cause corrosion. And the alkali-silica reaction (ASR) in some older concrete structures can also break down the concrete, possibly requiring a repair or complete rebuild.

Rebar corrosion can set in and it rusts, it damages the structure of the concrete.
