How to Repair Concrete Cracks
Concrete cracks in your home, on the ground, or on the side of a building are often a sign of evaporation or settlement. When concrete is poured, it has water and air throughout the mixture. As concrete hardens, the water often evaporates and causes the cement to shrink, which leaves small hairline cracks in the concrete. Larger cracks are typically a sign of a shifting foundation. Whether these cracks in the cement appear in your basement, on your front porch, or across your driveway, it’s likely that the soil beneath the mixture has shifted or washed away.
Repairing Concrete Cracks
Cracks in the concrete, especially larger ones can present opportunities for further destruction, and create entry points for insects, rodents and water beneath the concrete surface. Some cracks can be repaired on your own, but to ensure there aren’t deeper issues beyond the visible concrete crack, it’s best to call a professional to inspect and fix the problem.
There are a number of patching products on the market that are designed specifically for the use of everyday people. Liquid concrete repair kits, and epoxy-injection crack sealers are popular solutions for repairing cracked concrete. It is important that you understand the correct process and proper technique of filling cracks with these systems, which are only recommended for small cracks, or temporary fixes. If the foundation continues to shift, or water causes the cement to break more, then you’ll find yourself spending money to repair the same crack again and again.
If you decide not to call a professional, it’s important that you know which products not to buy in your attempt to seal a concrete crack. Experts suggest that you avoid using caulking and hydraulic cement because their ability to bond to the existing concrete is not strong enough to last. Ultimately, surface repairs to concrete cracks are only temporary, because cement is constantly shrinking, shifting, and expanding. Once cracks are formed, the natural movement of concrete will provoke further cracking over time.
Identify the concrete cracks around your home, and discover the best way to treat, repair, or replace the surface. Some measures can be done on your own, and others may require a specialist to diagnose deeper issues that you may not be aware of.
