Cracks in concrete not only look unsightly, but also can compromise the structural integrity and safety of the concrete surface. Therefore, it is important to repair and fill large cracks in concrete as soon as possible.

But how do you choose and use the best concrete crack filler for large cracks? There are different types of products for filling large cracks in concrete, depending on the size, location, and condition of the cracks. Some products are pre-mixed and ready for use, while others require mixing or pouring. Some products are based on epoxy, latex, asphalt, or mortar. Some products can fill cracks up to an inch wide, while others are suitable for smaller cracks. Some products can be applied with a trowel, putty knife, or sponge, while others need a caulking gun or a nozzle. Some products are flexible, durable, and weather-resistant, while others may shrink, crack, or peel over time.

Step 1: Assess the Crack

The first step is to assess the crack and determine its size, depth, shape, and cause. This will help you choose the right type of concrete crack filler for your situation.

Generally speaking, large cracks are those that are wider than  inch or deeper than  inch. Large cracks can be either horizontal or vertical, straight or jagged, uniform or irregular. Large cracks can be caused by various factors, such as ground settlement, frost heave, tree roots, heavy loads, or poor drainage.

To assess the crack, you will need a tape measure, a flashlight, a wire brush, and a vacuum cleaner. Follow these steps:

  • Measure the width and depth of the crack at several points along its length. Note down the average measurements.

  • Use a flashlight to inspect the inside of the crack. Look for any signs of water leakage, insect infestation, mold growth, or structural damage.

  • Use a wire brush to remove any loose debris, dirt, dust, or old filler from the crack. Use a vacuum cleaner to suck up any remaining particles.

  • Determine the cause of the crack and fix any underlying issues before proceeding with the repair. For example, if the crack is due to poor drainage, you may need to install a French drain or a sump pump to divert water away from the concrete surface.
