Do you really need concrete crack repair?

Concrete cracks are fairly common, and sometimes they’re nothing to worry about. However sometimes, they can develop into serious problems.

Home > Services > Concrete Crack Repair

 

What type of concrete crack should I be worried about?

There are a variety of different kinds of concrete crack. If you’re not sure what kind you have, just give us a call, and we’ll help you figure it out.

Hairline
concrete cracks.

These often appear on the surface of concrete, and should be monitored to ensure they’re not widening over time, or become a hazard. If that’s the case they need to be repaired straight away, to prevent water seeping through and potentially impairing the structural integrity of the building.

Shrinkage
concrete cracks

These are probably the most common of all concrete cracks. They happen because of shrinkage when it dries, and can be caused by too much water in the mix - which also reduces the strength of the concrete. They can be reduced with shrinkage joints in the right place, however if this important step has been missed, you may have an issue on your hands.

Settlement

If the ground beneath the concrete slab wasn’t compacted well enough, the ground may sink under the weight and take the concrete with it.

Structural

This is probably the worst kind of concrete crack, and if it runs through the whole slab repair might not even be an option. You may have to replace the entire slab.

What’s the concrete crack repair process?

After investigating what kind of concrete cracks you have, we’ll determine how aggressive the repair needs to be. We generally use a selection of epoxies and polyurea materials, and in many cases, the issue can be dealt with in less than an hour.

Overlays

Surface cracks and issues can generally be repaired with overlays, as long as the surface is prepared properly.

Concrete crack
repair - Partial-depth repair

This means cutting around the edges of the damaged area and removing the affected concrete. We’ll clean, or replace the reinforcing steel, and then place a repair mortar.

If required, we’ll cut out the damaged concrete, replace the reinforcing steel, and then replace the concrete too.

Why does concrete crack?

Generally it’s because of shrinkage, which pulls the hardening surface apart, however thermal movement can also cause problems. Rapid drying can also increase the possibility of cracking.

Concrete slabs can shrink over a centimetre for every 100 feet.
