Project Location: Clackamas, OR
Need an evaluation of our crawl space - minor water retention and an estimate on a sump pump or other solutions on waterproofing the area. Thank you
Project Location: Clackamas, OR
The last section of sidewalk leading to my front step, porch, landing, or whatever you want to call it, has sunken about 1-1/2 inches on one corner. I am looking for someone that can raise that section, to it's original height rather than cut it out, put in a couple of pieces of rebar, reform, pour and try to match the existing "exposed aggregate finish". The section in question is about 4x5 feet. I realize this is a "small job" to most construction workers, but I would really appreciate a bid to repair (raise)this potentially accident prone situation. I am retired so I can be around most anytime that one of your people could come look over the situation.
