Cracks in the concrete are always an eyesore. Identifying what type of break you will determine the correct products to treat it and minimize its recurrence. In this instance, we are not talking about control joints, only cracks that happen in-between control joints. The two types of cracks are active or static. Static breaks are no longer moving. In many cases, they may be viewed as hairline cracks but can be as wide as 1/2 inch. Active cracks can start as a hairline, but continue to widen as the slab is now two pieces of concrete separating farther from each other.
There are no treatments available to stop an “active” crack. The reason for this is due to the mass of each slab bearing too much on a thin material to keep it together. No longer active breaks, static, and hairline cracks can be treated in most cases. Depending on some linear feet and time to complete the process the user can use a cement, urethane, or an epoxy cracks treatment.
