Spalling Concrete RepairMost consumers have seen spalling concrete and wonder what are the spalling concrete causes? We find our sidewalks in front of our homes, or perhaps our garage floors looking like the one in the picture. One section of sidewalk might be fine, while the very next section is badly spalled. The fundamental cause is usually contractors who do not finish the concrete properly. They add water to the surface to keep it moist until they have a chance to finish it or they start finishing the surface before the bleed water has a chance to be absorbed. Both of these actions weaken the surface of the concrete making it susceptible to environmental conditions.

Spalling Concrete Causes

Consumers who live in areas that are exposed to constant freeze – thaw conditions may experience more severe spalling conditions in their concrete sidewalks and garage floors or driveways. Once the surface is weakened, water can get between the cracks and when it freezes will cause the surface of the concrete to lift up and particles will be dislodged.

In most cases it is only the surface that lifts up. The underlying concrete will not be impacted and will remain strong. The surface does not look great and can even devalue your home when it comes time to sell it.

In our next post “Spalling Concrete Repair”, we will quickly explain how consumers can do their own repairs. How they can make their garage floor, sidewalk or driveway look like new again. For more repair information around the home, click here.
