How to Fix Concrete Spalling with Alamo Concrete Work

Concrete spalling is a common problem that can occur due to a variety of reasons such as exposure to extreme weather conditions, the use of deicing salts, and other environmental factors. Spalling refers to the flaking or peeling off of the top layer of the concrete surface, which can lead to an unsightly appearance and also pose a safety hazard if left untreated. Fortunately, with the help of Alamo Concrete Work, concrete spalling can be fixed efficiently and effectively. In this article, we will discuss what concrete spalling is, what causes it, and how to fix it with Alamo Concrete Work.


What is Concrete Spalling?


Concrete spalling is a condition where the top layer of the concrete surface flakes off, exposing the underlying aggregate. It is typically caused by the freeze-thaw cycle in colder climates, where water penetrates the concrete and expands when it freezes, leading to cracking and weakening of the surface. This weak surface layer then peels away due to the stresses caused by foot or vehicular traffic, creating unsightly and potentially hazardous conditions.


Causes of Concrete Spalling


Several factors can contribute to concrete spalling, including:


  • Freeze-thaw cycles: As mentioned earlier, the freeze-thaw cycle is a significant cause of concrete spalling in colder climates. Water penetrates the concrete surface and freezes, causing the surface layer to expand and crack. When the ice thaws, the cracks become larger, leading to the surface layer peeling away.

  • Deicing salts: The use of deicing salts to melt snow and ice on concrete surfaces can also cause spalling. The salts penetrate the surface and corrode the steel reinforcing bars, leading to cracking and flaking of the surface.

  • Poor-quality concrete: Poor-quality concrete, which may contain too much water, air, or other contaminants, is more susceptible to spalling.


Improper installation: Incorrect installation, such as insufficient curing or finishing, can also contribute to concrete spalling.


How to Fix Concrete Spalling with Alamo Concrete Work


Fixing concrete spalling requires a systematic approach, which includes the following steps:


Step 1: Prepare the Surface


The first step is to prepare the surface by removing all loose or flaking concrete using a hammer and chisel or a power tool. The surface should be cleaned thoroughly with water and allowed to dry completely.


Step 2: Apply the Bonding Agent


The next step is to apply a bonding agent to the surface to improve adhesion of the new concrete. The bonding agent should be applied evenly using a brush or roller, as per the manufacturer’s instructions.


Step 3: Apply the Concrete Patch


Once the bonding agent has dried, the concrete patch can be applied. The patching compound should be mixed according to the manufacturer’s instructions and applied to the surface with a trowel. The surface should be smoothed out and left to dry for the recommended time.


Step 4: Finish the Surface


The final step is to finish the surface, which can be done using a broom, float, or other tools. The finish should match the surrounding area and be appropriate for the intended use of the surface.
