Hi all! I recently had a local contractor install a 250 SF brick paver patio in my back yard (polymeric sand). I'm concerned with how he pitched the patio. I've done a couple of "tests" with a garden hose and most of the water runs directly towards the houses foundation. There is a solid 7 foot buffer of a plant bed between the house foundation and the end of the patio. Should I be concerned with this and bring it to the contractors attention before I pay him? Located in Northeast if that matters. Any help is greatly appreciated! This is my first posting!!!
