Concrete work is expensive and time-consuming so when concrete is poured, no one expects a crack to form. If expansion joints or control joints aren’t properly constructed, or if the ground isn’t properly compacted before the concrete is poured, the concrete will eventually fail. If a crack develops in concrete, even the smallest crack will generally continue to expand until the concrete driveway becomes an alligatored and broken disaster. Besides making a facility appear neglected, cracks in concrete often cause concrete to eventually buckle and heave, making it dangerous for pedestrians to walk upon and even risky for cars to drive on.

Short of ensuring that your installation and situation are perfect, the best way to prevent significant cracks is to catch them when they are small and new. Although cracks in concrete can’t be made completely invisible, cracks can be repaired and made to look better. Concrete driveway repair can be done by anyone using polyurethane repair products. It does not take a professional to repair a simple crack and improve the appearance of a concrete driveway.

Hairline Crack Repair

It is essential to patch a hairline concrete crack, when it first appears. Patching a hairline crack in concrete will help prevent that crack from expanding into a much larger crack. Concrete Welder can be used to fill a hairline crack.  Catching the crack while it is insignificant will prevent further cracks.

A hairline crack that isn’t repaired right away often turns into a larger crack,on the onset of winter. Water in the crack freezes and expands the crack. Those with slightly cracked concrete sidewalks and driveways sometimes notice the crack expanding in the winter. Cracks left untreated can even turn into potholes. That’s why it’s important to take care of hairline cracks as soon as possible.

Clean away any debris with a broom, compressor or shop vacuum. As long as the cracks are clean and dry, there is no further preparation needed. Insert polyurethane crack repair cartridge into hand-operated dual-cartridge gun, attach tip and squeeze material into cracks. Use a straight edge or trowel to smooth the surface. Sprinkle topping sand over top to create a surface that is not slippery. The material will set up in minutes and your cracks will no longer be noticeable.

Hairline cracks repaired with polyurethane repair materials will be longer-lasting and stronger than other methods and the repairs are complete in minutes rather than days.
