One solution is to add fresh concrete on top of the old surface Why you need to use a concrete bonding agent The cement within a concrete mix doesn t contain any natural bonding agents so when fresh concrete is added on top of an existing layer of concrete the two won t join together Once cured the new concrete will simply sit on
