Is your concrete slab littered in cracks, high points, low points, or other defects? If so, you may require structural concrete repairs. Damaged concrete slabs are highly susceptible to additional damages from the weather, as well as chlorides found in ice salts. Cracks in concrete allow moisture and salt to easily penetrate surfaces, causing corrosion of structural reinforcement, and ultimately, spalling. It is best to repair commercial concrete slabs at the first sign of issue. Additionally, regular maintenance helps to prevent costly damages from arising.

 

What are Concrete Slabs?

Concrete slabs are made from steel reinforced concrete. These durable slabs are commonly used as the foundation for modern homes and buildings. Thinner varieties can also serve as the base for a patio or other exterior paving. Slabs are built to last, but that doesn’t mean they will last forever. Without proper maintenance, concrete slabs may encounter a variety of issues that require repairs.

 

Types of Concrete Slab Cracks

Cracks in a concrete slab can be found just about anywhere—from a garage to a restaurant patio. There are different types of concrete cracks, and by judging factors such as the crack’s size, location, and growth, you can assess its underlying cause and if it is serious or not. There are shrinkage cracks; cracks caused by thermal contraction, subgrade settlement, and overloading surfaces. Some cracks are low-risk cosmetic issues, while others can signal more serious issues with the foundation and require costly repairs. Some common causes of concrete cracks can be avoided with high quality construction. There are countless mistakes and things that can go wrong when pouring a concrete foundation. Stick with a professional company with a proven reputation and reap the benefits of quality commercial concrete slab installation.

 

How Often Should You Conduct Concrete Slab Maintenance & Repairs?

The general rule of thumb for concrete slab repairs and maintenance goes as follows:

Use a polyurethane sealant to rout and seal off concrete cracks once every 2-3 years.

Add a penetrating silane sealer + rout and seal any cracks in concrete slabs once every 3-5 years.

Repair cracks in concrete slab, and add a generous 3-coat traffic membrane to the foundation once every 5-10 years.

*These time frames are just a general guideline. The amount of traffic, and overall wear and tear, local weather conditions, along with other factors also influence maintenance regularity.

 

Signs You Need Concrete Slab Repair

How do you know when you need concrete slab repair? Over time, you’ll typically start to notice some changes in concrete—either cracks in the slab, patches of discoloration, or low spots. Some of the most common signs you require concrete slab repair include:

• Cracks in concrete
• Discolored concrete
• Delamination of surfaces
• Concrete blisters
• Dusting, a fine powder that builds up on surfaces and can easily be wiped away.
• Efflorescence, the white patches where salts remain trapped in surfaces after moisture evaporates. There are a variety of methods used to clean efflorescence.
• Low spots—these ‘low’ areas can impact drainage.
• Pop outs in concrete—chunks of concrete that leave behind a hole measuring anywhere from ¼-inch to 2 inches. They can be as large as one-foot in diameter.
• Scaling and flacking of mortar—this is often caused by freeze and thaw cycles. It is less likely caused by a chemical corrosion.
