Hello, I have an aging walkway with pavers but there seems to be a concrete surface underneath. The contractor was saying that he will break the concrete and install pavers. I am concerned how it will affect the foundation of the house (if any) where the concrete is against the wall of the house near the front door area. So not sure if I should pull the dilapidated pavers and go concrete or break concrete surface underneath and go with pavers? Also I am planning to take the natural area out of mosquito reasons and go with concrete or pavers. Thanks in advance!!
