I only have a little 3'x4' cement patio in my backyard. When I bought the home last year (it was built as a spec home) that's all it came with. Here's my question. If I wanted to expand that patio out, I have someone who will build me a 7'x16' cement patio, but I have a sprinkler system already installed, would it be difficult to do? Even if I had capped off the sprinklers, wouldn't the weight of the cement be detrimental to the sprinklers? Or would I have to hire someone to reroute them? Any advice would be much appreciated.
