Concrete Repair: Addressing Jacksonville’s Common Issues

Table of Contents


Concrete is a widely used construction material in Jacksonville, known for its durability and longevity. However, over time, concrete can develop various issues that require repair. In this blog post, we will identify some of the common concrete problems faced by Jacksonville residents and discuss effective repair solutions.

Cracks and Spalling

One of the most noticeable signs of concrete damage is cracking and spalling. Cracks are thin lines that appear on the concrete surface, while spalling is the peeling or flaking of the concrete layer. Both of these problems can be caused by different factors, such as:

  • Shrinkage: When concrete is poured, it contains water that evaporates as it hardens. This causes the concrete to shrink and create internal stress, which can result in cracks.
  • Settlement: When the soil under the concrete slab shifts or settles unevenly, it can create gaps or voids that can make the concrete crack or sink.
  • Freeze-thaw cycles: When water seeps into the concrete and freezes, it expands and creates pressure on the concrete. When the water melts, it leaves behind cracks or holes that can weaken the concrete structure.
  • Corrosion: When steel reinforcements inside the concrete are exposed to moisture or chemicals, they can rust and expand, causing the concrete to crack or spall.

To repair cracks and spalling, you need to follow these steps:

  1. Clean the area: Use a wire brush, a broom, or a vacuum to remove any dirt, dust, or loose concrete from the damaged area.
  2. Fill the cracks: Choose a concrete crack filler or epoxy that matches the color and texture of your concrete. Apply the filler or epoxy into the cracks using a caulking gun, a putty knife, or a trowel. Smooth out the surface and let it dry.
  3. Patch the spalling: For larger cracks or spalled areas, you may need to use a concrete patching compound. Mix the compound according to the instructions and apply it over the damaged area using a trowel. Level the surface and let it cure.

Here is a table that compares some of the common concrete crack fillers and epoxies available in the market:

Settlement and Unevenness

Another common problem with concrete is the unevenness or sinking of the slabs. This can happen when the soil under the concrete erodes or compacts over time, creating voids or gaps that cause the concrete to lose its support. Uneven or sunken slabs can pose a tripping hazard and affect the drainage of your property. To repair uneven or sunken slabs, you need to use a technique called slab jacking or mud jacking. This involves drilling holes in the concrete and pumping a mixture of cement, sand, and water under the slab to raise it to the desired level. Slab jacking is a fast and cost-effective way to restore the level and stability of your concrete.

Discoloration and Stains

Concrete can also suffer from stains and discoloration due to exposure to dirt, oil, grease, chemicals, or organic matter. Stains and discoloration can make your concrete look dull and unattractive. To repair stains and discoloration, you need to follow these steps:

  1. Clean the area: Use a degreaser, a detergent, or a concrete cleaner to remove any surface dirt or grease from the concrete. Scrub the area with a stiff brush or a power washer to loosen any stubborn stains.
  2. Apply a stain remover: Choose a stain remover that is suitable for the type of stain you have. For example, you can use bleach for organic stains, vinegar for rust stains, or muriatic acid for mineral stains. Follow the instructions on the product label and apply the stain remover to the affected area. Let it sit for the recommended time and then rinse it off with water.
  3. Seal the concrete: To prevent future stains and discoloration, you can apply a concrete sealer to the surface. A concrete sealer will protect your concrete from moisture, UV rays, and chemicals. It will also enhance the color and shine of your concrete. Choose a concrete sealer that matches the finish and look of your concrete. Follow the instructions on the product label and apply the sealer to the dry and clean concrete surface.
