I'm looking to have a concrete driveway poured an wanted to get some idea about how much I'll need an the prep for it.I will hire for the pour/finish. It currently has a few inches of gravel and is level.It will be 65ft by 10 an I'm guessing 5inch (minimum).There is also a sidewalk that's 30 ft by 3. How much will I need to order an how many inches of gravel will I need ,? it's on a pretty flat area an gravel is compacted .It's in TN. I also have 14 gauge welded mesh an the supports used for rebar...will this work ok, ? I can double it if needed also. Building forms also an wanted to know if just outer edges are needed or middle joints also. Any additional info is appreciated .

Hello, This isn't a "home" project per say but rather one about preservation and masonry. I am overseeing the rehab of a historic structure (a Powder House, which was used to store munitions during the war of 1812) and need to create a temporary patch of sorts. If you look at the picture below, the structure has a gaping hole (probably 4x4) that I'd like to patch to keep water, ice, snow, etc. temporarily. The entire structure is going to be rebuilt but for now, what are my options to close that hole? I have little to no experience with masonry but assumed I'd need to use some type of metal mesh screening and a quickcrete type mixture? Thanks in advance! [ATTACH]71823[/ATTACH]
