What is the best way to repair cracks in concrete?

Over time, concrete slabs get cracks. You can restore them by hiring a sidewalk repair contractor NYC, as you cannot avoid them due to concrete’s rigid nature. Although one might think they are not serious, they can expand into fissures and require expensive repair. Shrinkage, temperature changes, and uneven drying of concrete lead to cracks and fractures in the slab.

Significance of Filling Cracks in Concrete

Concrete cracks and fixtures indicate deeper underlying issues. The first thing to do before starting repair is to find out the severity of the crack. Hairline cracks are visible from the inside only and are usually safe. You can fill them up to prevent water seepage.

However, cracks larger than ¼ are visible, both from inside and outside of the building. You need help from a professional to get them inspected.

Concrete Cracks Repairing

Here is a step-by-step guide to repairing cracks in concrete:

Choose the Right Repair Product

You cannot repair concrete surfaces with concrete. You need to use a concrete repair mix. For example, latex patching material, mortar mixes, and epoxy compounds.

Prepare the Cracked Area

Use a hammer and chisel to remove crumbling and cracked concrete. Chip to a depth of 1 inch under the surface. Rise and scrub the area thoroughly to dislodge loose pieces.

Use the Repair Product

Cure the Area

You need to cure the concrete area after repair. It should be dry before you paint or expose it to water or traffic. This is necessary to ensure that the repair lasts. The cure time can vary depending on the repair material you use. You can check the label on the crack filler to know the curing time.

Preventing Cracks in Concrete

There are many effective ways to prevent concrete cracks. You can use these measures while laying the slab. There are other ways to prevent cracks in existing sidewalks, driveways, or patios.

Seal Concrete

Water is the main culprit behind concrete cracks. Using high-quality concrete every 3 to 5 years stops moisture from soaking into the porous concrete. This will prevent cracks as well.

Avoid Planting Trees Next to Concrete

If you plant trees adjacent to the sidewalks, driveways, or patios, eventually they will exert pressure on the concrete. The roots will cause cracks and upheaval of the slabs. It is best to create a buffer around trees to prevent this.

Work on Drainage System

Water is concrete’s enemy. Standing water on a concrete sidewalk or driveway, or water that drains towards the foundation of the house/building is damaging. The surfaces retain water and eventually crack. 

You can stop this by ensuring that the gutters, downspouts, and the grading surrounding the home are clean. Ensure that the rainwater drains away from the foundation. As a result, no excess water soaks into the concrete and there is no water wastage either.

Set the Sprinklers Away from Concrete Surfaces

Watch out where your sprinklers are. See that you limit the amount of water near the concrete surfaces. Concrete absorbs water and this leads to cracks. Direct the sprinklers away from your concrete foundation, patio, or driveway to prevent water from soaking into the concrete.
