Cracked Concrete And What To Do About It?

Yes, you can DIY, however, we strongly suggest hiring concrete professionals for better results and to save you time and money. Don’t let those imperfections linger, here’s how to fix them!

How To Fix Cracked Concrete

Here’s what you’re going to need:

  • Hammer
  • Chisel
  • Wire brush
  • Putty knife
  • Concrete repair mix
  • Mason’s trowel

If you have everything, then you’re all set for the following steps!

Step 1: Decide which concrete repair product to use.

You will want to use a concrete repair mix to repair cracked concrete slabs. You can easily find the concrete mix online or at home centers nearby.

Other options include epoxy patching compounds, latex patching materials, and mortar mixes. Mortar mixes are suitable for big cracks while the other two options are better for small cracks.

Step 2: Prepare the area.

Knock away the loose concrete by using a small hammer and chisel. Use a wire brush to remove all the loose and lingering particles.

At this point, expect the project to get messy. That said, we suggest spreading a tarp around the concrete patch and using protective gear for your safety.

Step 3: Fix it!

Now, you’re all set to fix the cracked concrete using your selected concrete repair product. Follow the manufacturer’s guidelines to ensure the complete repair project is completed properly.

If you’re using the mortar mix, make sure to smoothen the concrete patch to level with the surrounding concrete. Leave it for 2 hours and cover the area using a plastic sheet to keep it moist. Experts recommend sprinkling water on the patch every day for a few days until the surface hardens.

Concrete Crack Repair Methods

There are several methods that you can use to repair cracked concrete. It is essential to evaluate the type of crack to choose a suitable fixing method. Types of concrete cracks include shrinkage cracks, hairline cracks, expansion cracks, heaving cracks, settling cracks, overload cracks, crazing cracks, and crusting cracks.

Here are a few methods that work:

Epoxy Injection

This method is best for cracks that are as narrow as 0.05 mm. The epoxy injection method involves sealing cracks by injecting epoxy under pressure. In fact, the epoxy injection method is one of the easiest ways to repair cracks on various structures as it works on any application. The process is pretty simple. All you need is a piece of injection equipment, capping paste, an injection port, and injection resin.

Stitching

The stitching method involves drilling holes on both sides of the crack and grouting in U-shaped metals to hold the concrete together. You can use a non-shrink grout or epoxy resin-based bonding system to anchor the legs of the staple on the holes. Keep in mind the length, location, and orientation of the staples should vary. As a result, tension is distributed on the concrete and not on a single plane.

Routing and Sealing

The routing and sealing repair method is suitable for flat horizontal surfaces such as floors and pavements. This concrete repair method involves enlarging the crack and having it filled and sealed using a joint sealant. This method is relatively simple compared to the procedures used in epoxy injection methods. Moreover, routing and sealing are also suitable for patterns and larger isolated cracks. The routing and sealing method can also be used to waterproof a concrete surface.

Drilling and Plugging

The drilling and plugging method is recommended for cracks that run in reasonably straight lines and are accessible on the other end. This type of repair method is commonly used to repair retaining walls with vertical cracks. To repair concrete properly using this method, drill a hole that’s 50 to 75 mm in diameter centered on the crack. Then, use grout to prevent movement of the sections that are adjacent to the crack. Note that it is essential to fill the hole with resilient material for better support.

Final Say

Cracked Concrete remove and replaceIt can be easy to fix cracked concrete as long as you plan and know the right procedure. Understand the best repair method, find the right concrete repair product, and use the exact tools needed to make the work easier for you.

The basic concrete crack repair steps are pretty easy to follow. However, it is strongly advised that you follow the manufacturer’s instructions. There are several repair methods to use depending on the type of crack. Carefully examine the cracked area to come up with the right fixing method and to save resources too.

Finally, don’t hesitate to consult a professional to ensure things are done correctly. Failure to properly repair cracks in concrete can result in having to completely replace concrete patches in the future.
