How To Repair Concrete Cracks Without Calling A Pro

Now everyone has a concrete-made patio and sideways and after some years, cracks are noticed. Cracks seen on concrete floors, slabs, or walls have adverse effects on the beauty of a home or office. Then it is recommended to go for concrete repair. Most of the time, it is seen that contractors won’t say about how to repair such cracks and what are the solutions. Concrete slabs can break or deteriorate for a variety of causes, depending on how they are used and built.

Cracks in concrete slabs are often repaired using epoxy injection or by casing the crack’s surface, and even though this may look as if the issue is solved, these fixes repeatedly go pear-shaped, resulting in call-backs or other issues. Carbon fiber solutions provide a more long-lasting solution as the material is used to repair, fortify, and strengthen not just the damage and crack, but the complete affected area, resulting in a fail-proof solution.

Problems with concrete

Lack of steel brace, a bad concrete mix, insufficient thickness, settlement, hydrostatic pressure can all lead to cracks. Under tiles or hardwood used for beautification, concrete crack or holes might be seen. Soil elements such as radon and moisture can flow through these cracks in a basement setting, and the extra moisture can lead to mold and rust problems. This results in not only health issues for the residents, but also harm to any furniture or other things.

How to repair cracks?

Whenever a narrow crack on concrete slabs or concrete walls is noticed, it is recommended to fix it immediately, or else it will get bigger and costly to repair. When it can’t be repaired through a DIY job, it is better to call a pro and fix the cracks in the concrete.

Tools needed

  •         Hammer
  •         Chisel
  •         Trowel
  •         Putty knife
  •         Wire brush
  •         Concrete repair mix

Steps to follow

Select a concrete-repair product

Concrete cannot be used to fix concrete surfaces. Rather, use a concrete repair mix, which can be found at home stores and also available online. Epoxy compounds, latex patching material, and mortar mixes are the options to choose from. For wider concrete repair or fixing fragmented edges, better to use mortar mixes. But when it is hairline cracks or up to 18 inches cracks,it is wise to opt for other options.

Make sure the cracked area is ready to be patched

To initiate the repair work, knock away any cracked, cracking, or loose concrete with a small hammer and chisel. Chip to approximately a one-inch depth further down the surface. After that, carefully clean the area and brush it with a wire brush to do away with any loose, residual particles.

Please remember that this is a sooty job. For making the cleanup process easy after the repairing job is done, it is a good idea to put a polythene sheet beneath the work area. Don’t forget to wear all the protective gear before initiating the repair job.

Repair the crack with the substance

Latex or epoxy: Apply an epoxy or latex patching product (see example on Amazon) to concrete cracks that are 18 inches broad or narrower. A mason’s trowel or a putty knife is used to apply the material. Push the substance into the crack throughout, then level it with the surrounding concrete. Different combinations have different cures; don’t forget to read the directions on the product chosen.

Mortar mix: Use a mortar mix to fill in bigger cracks in concrete. It’s quite easy to create the mix.

Just blend some Portland cement with three parts of sand and water as required to make a thick paste. Alternatively, buy readymade mortar mix from a local hardware store or online. Moisten the area where the crack is open, then apply the mortar mix with a mason’s trowel or a putty knife. Make a point of pushing down firmly on the applied substance to remove any air pockets. Finally, level the spot with the surrounding concrete by smoothing it out. Allow it to sit for two hours before covering it with plastic sheeting to retain moisture. Every day for a few days, or until the surface has solidified, sprinkle water under the plastic.

Take that lesson to heart with any concrete repair, and start the job to fix any concrete cracks. Determine what caused the damage, prepare the area by removing any unsound concrete and pollution, and then install a fix that will address the issue.

Concrete repair assessment

The most common reason for assessing concrete is that it has been damaged in some way; there is no such perfect concrete. Within some years it needs to be repaired. So how to assess the damage. Determine whether the damage is structural or superficial to initiate.

A hammer and some spray paint are useful tools to have at this stage of the research. Delaminated areas can be defined with paint after pinning the concrete surface with the hammer. Rather than the severe ringing of sound concrete, delaminated portions release an unclear hollow sound. Confirm to have a tape measure on hand to estimate the range of the repairs.

There are some easy repairs or need for resurfacing the entire piece of concrete slab, so it’s better to call a professional and ask for the quotes for the repair job. The best part about resurfacing is that it gives the sidewalk or patio the appearance of a brand new one and allows you to walk on it within 12 hours. Or if complete replacement of concrete slab is needed, the size, width and design can be changed. It’s recommended to talk with a few professionals, get their quote and then decide to hire the best one.


Ignoring cracks and adopting quick concrete repair techniques can only lead to more problems. Carbon Fiber reinforcing materials have been shown to provide long-term solutions to a range of concrete cracks and damage, as well as providing contractors with a long-term option for fixing the issue.
