A concrete floor creates a solid surface for all sorts of activities. Over time, blemishes can occur on a slab, making you wonder what can be done to repair it.
Resurfacing concrete is a solution to the damage that can make the surface look new. On the other hand, some critical problems might require an in-depth repair of an underlying issue.
In many cases, cracks, spalling or pitting are signs that you need concrete resurfacing. But, understanding more about these problems can help you determine if there is a more serious problem that needs fixing.
Concrete Cracks That Can Be Resurfaced
Cracks are a common issue in concrete floors that can come from shrinkage during drying. A cosmetic crack on the surface can be filled in and resurfaced.
Small cracks, under 0.3mm in width, are normally cosmetic problems that can be fixed with resurfacing. A wider crack should be inspected by an expert to determine if it could be a sign of an underlying issue that needs other repairs.
Also, if the two edges of a crack are at different heights, it will need a more in-depth repair before it can be resurfaced. Any crack that goes through a slab needs to be fixed by experts.
Spalling That Can Be Resurfaced
Spalling concrete looks like the surface is flaking, chipping or peeling away. There are several causes of this damage, including:
- Freeze-thaw cycles
- Bad finishing techniques
- Improper curing
- De-icers
- Poor concrete mix
Luckily, if the damage isn’t too deep into the slab, spalling can be repaired and resurfaced. However, fixing this issue as soon as possible is critical because the longer it continues, the more likely you will face an expensive slab failure.
Pitting That Can Be Corrected With Resurfacing
Pitting is any hole or many holes in the surface of a concrete floor. Pitting might be caused by an impact, a botched application or result from spilled chemicals.
Like with spalling, if pitting isn’t too deep into the slab, it can be resurfaced. First, the pits must be filled to create a level surface.
