A concrete surface goes through a lot of use and abuse during its lifetime. It endures the changes in climate every single day. It gets exposed to snow, ice, and rain. It also shifts and cracks especially in high traffic areas. When concrete damage seems imminent, it is important to think about which solution to go for. Have it replaced? Or have it coated with an overlay or coating? Here are the top three things you have to consider when you are torn between concrete resurfacing and concrete replacement.
The Level of Damage
Just how much damage does the concrete slab have? Cracks are the most common types of damage. If the crack is just about a quarter of an inch deep, it can still be repaired and the entire slab can be resurfaced. However, if the crack is much deeper and wider, a repair can only do so much. The cracks may recur and it would only make it costly for the owner. If the damage is irreparable, the best option is to replace the entire slab and find out what causing the big cracks.
Age of the Concrete
Concrete is a durable material but it does get weaker as it ages. If you are choosing between resurfacing concrete and replacing your concrete space, it is important to consider the age of the slab itself. If it has been around 20 to 25 years since it was first installed, it is better off replaced with a new concrete mix. The brittle slab won’t be able to hold up a new coating or overlay. Also, old concrete is more prone to damage. It may look good for now with a new coating but expect new damage to appear soon.
Time and Budget
When choosing a solution to concrete damage, think about how much time and money you would be able to invest in a project. Replacing the concrete takes more time than resurfacing it. The old slab must first be removed before the new mix can be poured. Then you wait at least a month for the concrete to properly cure. It is also more expensive to replace the slab because it involves more work and more new material. If your time and budget are limited, you might as well resurface the concrete to acquire a brand new look and improved functionality.
