Concrete Floor Repair Jobs

All Concrete Repair Jobs are typically done in one of two ways. The first is to patch the hole or crack with new concrete, which is not always possible depending on the size and depth of the damage. The second way is to replace the old concrete with new concrete.

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

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. Hairline cracks are popular in new, entirely located within the concrete and are affected by the plastic shrinkage phenomenon. As the name implies, these cracks are tiny, trying to measure about 0.003 inches (0.08mm) in size, and they can be very shallow. Cracks can appear as a result of changes in temperature, concrete heat, humidity levels, and wind speed at the concrete's surface. These factors could cause rapid evaporation, either in hot or cold weather.

Shrinkage

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. Over time the ground beneath the slab may settle unevenly, ultimately causing cracks to form.

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. The major reason for structural cracks in residences' foundational principles is downward loading or settlement. Almost all applied load structural cracks (pressure or heavy machinery around the block wall) are nearly completely flat and appear 16" to 48" (40.6 to 122cm) from the top of a wall. They are more common in block concrete foundations.

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. They can be made from asphalt, concrete, or stone.

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. Repair work can be done in a matter of hours.

If required, we’ll cut out the damaged concrete, replace the reinforcing steel, then replace the concrete. We'll assess the damage and then decide on the best course of action.

Repairing Concrete Cracks

The best method to repair concrete cracks is by using an epoxy resin that will bond the two surfaces together and fill in any voids left behind from previous damage. There are many different ways people have tried patching these cracks, but this is the most effective way because it provides a permanent fix that will not degrade over time like other methods.

Cleaning is essential when repairing concrete cracks

Chipped, flaking, or crumbling concrete can cause the repair materials to fail. Therefore it is essential to clean and remove all loose material prior to performing any necessary repairs before beginning the crack filling process.

How long does the repair process take?

The time frame for each job is different, but our team always works quickly and efficiently to get the job done as soon as possible. The time it takes to repair concrete is determined by the nature of your problem, which includes the extent of the damage to the concrete. Before you begin improving yourself, keep in mind that this will require some work and usually 48 hours before walking on top again after completion.

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.

Cracks in concrete are usually a result of improper placement, with unsatisfactory expansion and mixture blending throughout slab pouring. Suppose you notice one or more cracks on your flooring.

In that case, it is essential to get them fixed right away because over time they will get worse resulting in more significant damage making the concrete floor repairs more difficult and costly.
