My back patio slab is 30x11 feet. The concrete has extensive cracks and is uneven. Breaking all this concrete is going to be my absolute last resort. I have the "walk maker" I was going to make a little walk way through my garden. To use this to cover the patio would be -165 molds.... 165 bags of concrete. Then unlocked into 16x16 inch pavers. This would mean I would need about 248 pavers to cove the patio... I was going to do this ten level it with mortar. This seems like it is going to be a costly project. Does anyone have any other ideas of what I can do? From the slab to the door is 8-10 inches.
