The foundation cement structure and bolts and septic tank and leach field and block walls were left remaining.I had to have an engineer certify that the cement was intact and could be built on. 

After discovering that my old shower walls were built with drywall instead of a more appropriate hardie board or cement board (that was a fun discovery), I started getting estimates from contractors for a complete tear out and replacement.  

The cement covering on the foundation on right side of the house is deteriorating, cracking and coming loose.

Just as you should oil a drill bit going through steel, or add water the the saw cut when sawing cement, add water or otherwise keep it moist. make the asbestos NON-Friable.

I also had the sewer pipe replaced and need estimates to repair the cement in the basement.

I have to install fire escapes and enclose the furnace room with cement walls.

Old-school vinyl sheet is glued and tile is cemented, so those are no fun to remove when it's time. 

If a slab, you can use self leveling cement to float out the slope, then lay down whatever floors you want from there.

They were pretty solidly cemented in because they'd apparently been leaking for awhile and the calcium buildup made it very difficult to get them out.

We were working on a flip (the home circa 1930's did not have a sump pump nor drain tile), & all of a sudden after a mild rain I got pools of water on the basement floor around the back wall (lousy hydrostatic weak cement-block) & the one corner close to the driveway.
