Cracks and fissures in concrete are unsightly, and they can make your work floor dangerous. Fortunately, your maintenance crew can repair them yourself, not only saving money but also avoiding the inconvenience of having downtime for your warehouse.

What is the Difference Between a Crack and a Fissure?

Cracks are caused by external forces such as water, frost, or heavy weight. Fissures are cracks that penetrate to the underlying ground material, usually from within.

Fissures are usually repaired with a soil cement grout while cracks can be filled with an epoxy sealant.

Why Does Concrete Crack?

Two main factors cause concrete cracks. One is the shrinkage of the concrete because of the drying or freezing process. This can cause a hairline cracking of the concrete, leading to horizontal and vertical cracks on the surface. The other reason for concrete cracking is the expansion that occurs when water gets to the surface from below and freezes, causing horizontal cracking.

The first step in preventing cracks in concrete is to seal any leaks or holes in the foundation before pouring any concrete. Allowing water to seep through will result in cracks eventually as it expands when frozen and shrinks when drying out.

We should also identify the cause of the problem before deciding on a possible solution. For example, suppose a lack of cement causes it. In that case, we should add some cement to the mixture, or else if it is because of high expansion and contraction, we should stop pouring concrete when there are large temperature fluctuations.

Tools and Materials You Need to Repair Concrete

Concrete cracks are a common problem that you will likely encounter at some point. These cracks can appear on any concrete surface. They are caused by a variety of factors, including changes in temperature and poor building practices.

Repairing concrete cracks can be done with a variety of materials, such as cement and epoxy concrete patch products. You will need to have the materials ready before starting the concrete crack repair process.

The tools and repair material that you will need depend on the type of crack. For hairline cracks, you’ll need a concrete caulk sealant. For vertical and horizontal cracks, a special concrete repair product is a better option.

Fixing a cracked concrete slab is not an easy task, but there are ways to do it most efficiently.

Tools you need:

• A stiff broom handle or 2×4
• Cement mix (2 parts sand to 1 part cement)
• A bucket of water
• A large, clean cloth
• A container of wet mortar (optional)

How to Repair Cracked Concrete

Cracked concrete is a common issue in many homes and businesses. It can cause uneven surfaces, water seepage, and even mold growth.

Here are steps to repair concrete cracks:

1) Clean the area with a wire brush of any debris or loose material, which may impede the repair process.

2) Make sure you have all materials needed for repair in your possession before starting this project.

3) Scrape off any loose concrete from the surface with a chisel, using a hammer if necessary.

4) Use a hammer to drill out holes in cracks and holes with an 8 mm bit or larger depending on the depth of the hole or crack.

5) Mix cement powder and water until it forms a paste-like consistency (called “mud”).

6) Apply a thin layer of material using a brush

7) Apply material with a thicker coat using a roller or brush

8) Allow drying for the recommended drying time, or 24 hours before use
