Hi, I have a concrete patio slab with brick pavers on top of it. The water drains towards the kitchen area of the patio and creates a big puddle there whenever it rains or I am pressure washing the patio. I have plans to just install a catch basin at around the lowest point and then have that drain out to a dry well. In order to do this I have to break up the concrete underneath of the pavers, and the concrete is fairly thick and reinforced. Would it be ok to just use a jackhammer to break up the part I need? It is about a 10 foot by 3 foot section that I need to break up in the middle of the slab. I dont care about how straight the edge lines are since I would never see them so I am not sure if I would also need to buy a saw or not. Any help or suggestions would be greatly appreciated!
