Why Concrete Fails in Florida & Georgia

What causes sunken or cracked concrete

Cracks in a concrete slab

As concrete ages and is exposed to the elements, it wears, becomes pitted, and can start to look run down and dilapidated. Residential and commercial property owners should be mindful of the condition of their concrete pavement and take appropriate measures to keep concrete in its peak condition and reduce maintenance costs. If your concrete looks cracked, uneven, or worn out, it’s time to call a concrete contractor.

What Causes Concrete to Crack?

Ever admired a beautiful concrete walkway, porch, or driveway only to see a large crack? Cracks are inevitable in concrete, but planning will minimize your chances of getting one during your next project. Concrete cracks for several reasons, but the following are the most common reasons we see:


One of the most common causes of cracks is shrinkage due to moisture. This can be due to poorly mixed concrete – usually with too much water. Shrinkage can also be exacerbated by overmixing the concrete. While shrinkage cracks are often barely visible and are only a hairline in width, they can extend through the entire slab, becoming a larger eyesore.

Expansion Cracks

Concrete is also prone to cracking because of expansion. In extremely hot conditions, concrete slabs expand as they warm up. This process will cause the slab to be highly stressed. Any concrete slab or brick wall in its path will be pushed against by concrete’s inevitable expansion. A crack will result if neither can flex.

Premature Drying

Cracks in the surface, called crazing, resemble small spider webs or shattered glass. Whenever a slab loses water too quickly, cracks can appear. Despite their unsightliness, crazing cracks are not structurally harmful, though if left unattended can become dangerous and cause people to trip.

What Causes Concrete to Sink?

Since concretes handle a substantial amount of weight daily, all concrete is susceptible to failure at some point – like sinking. Sinking can occur for several reasons, including:

Inadequate Slab Support

A concrete slab that is only partially supported by soils can collapse, crack, and become unlevel. A good, uniformed foundation can prevent slabs from sinking.

Soil Types

Different soil types can bear different loads. A heavy concrete slab will cause soil that isn’t load-bearing to compact and settle, leading to sinking, cracking, crumbling, and unevenness of the concrete.

Soil Washout

Sinking concrete can also be caused by soil erosion. Water is capable of washing away the soil beneath your concrete slabs, which supports its weight. Whenever this occurs, a void is created beneath it. Your concrete slab can sink over time if there is nothing to hold it up.

What Causes Stained or Patchy Concrete?

Have you ever seen homes with stained concrete in their driveways? Sometimes the stains are subtle, but despite their similar colors, it makes the driveway seem blotchy. It makes you wonder what might’ve gone wrong and what can be done to avoid making a similar mistake with your concrete project. Stains and patchiness can happen for several reasons, including:

Material Inconsistencies

Consistency is key to an attractive concrete surface. A harmonious and even appearance requires all concrete portions to be mixed at the same ratio. Your contractor should choose materials that adhere to the ASTM (American Society for Testing and Materials) standards so that concrete works consistently.

Replacing Cement with Alternative Materials

Contractors and homeowners may prefer to use recycled materials in a concrete mixture to make it more environmentally friendly. But, because these replacement substances behave differently than traditional concrete, the color they produce may not be the same as existing concrete.

Unskilled Craftsmanship

The surface appearance of concrete can be influenced by how it was laid and the weather conditions. Expert concrete contractors take these factors into account to minimize pouring accidents. Failure to do this correctly can result in discolored concrete.

Concrete sealants are the best way to resolve a lot of these problems. Sealing your concrete properly at the beginning is the best way to prevent discoloration by giving your concrete an even and uniform surface. If used properly, concrete sealers can prevent concrete blotchiness to a great extent. At Alpha Foundations, we take care of this with our SettleStop™ solution.

What Causes Street Creep?

Concrete roads expand during the warm months, causing distress to your driveway and foundation. Street creep occurs when the concrete shrinks or expands due to thermal expansion and contraction. To prevent concrete slabs from settling and cracking, contractors commonly create expansion joints between them.  This solution may prove ineffective for preventing street creep over time as the joists can become clogged up with sand, rocks, and dirt as they widen when the concrete contracts in the winter – because even Florida can get a little nippy.

At Alpha Foundations, we offer expert concrete creep repair services and provide free consultations to homeowners just like you, because street creep affects every home differently.
