i have some gaps and cracks in my back area. its the slab from the old garage and pavers that leed from it to my back door. water comes down this area to my back door. there is a very small swale right in front of the door, pavers. it is connected to a concrete swale, 14" wide x 2" deep, that goes down the side of the house to the front.
anyway. what i want to know. the gaps and cracks in the slab and pavers. how much will filling them with sand work ? doesn't need to completely seal, just needs to stop the funeling of flowing water down to the foundation into basement.
or, is there a better product i should use ?
