There are conditions wherein a concrete project that can no longer be patched up by any compound and resurfacing product. The best course of action, in order to save time and money, is to go for concrete removal.
What are the conditions that call for concrete removal?
There are situations when the damage in your concrete can be fixed by resurfacing, but there are a myriad of conditions wherein total removal and replacement will be much more economical.
• Deep, widespread cracks
Extensive cracks cannot be returned to its original polished state no matter how many resurfacing you do. These cracks develop from low sub grade used, erosion, exposure to extreme weight and others.
• Slabs that sink
This is caused by a sub grade that is not well-prepared. It may be that loose dirt was used for the sub grade or it was compacted. Storm water creeps under the concrete surface, so it becomes hollow and unsupported. In due time, the slab will sink, especially when subjected to heavy loads or weight.
• Frost heave
This happens in places with cold climates. The moisture that is in the ground solidifies pushing the concrete upward.
• Spalling and Spitting
Resurfacing may address the situation, but is not made to last. Complete removal and replacement is the only answer to this problem.
