Couple of questions : Video shows long shadows when that load of concrete was being discharged . Did they form and pour the same day, or set forms first and then pour the next day ? 1) How many CY did they pour ? I assume they placed the concrete in one day ? 2) What was the design strength...

Suggest you purchase a couple of test kits to check the water vapor coming through the floor . You can purchase from a local Geotech Testing firm . Geotech can give you the acceptable range for water vapor in a 24hr test. Water vapor coming through the slab will make the floor sweat. Water...

I want to thank all of you for the great information in these posts. Sorry for being slow to reply, I have on the road this week.

There are two problems: 1) The wall base plate should attach to bolts cast into the concrete 24" O.C. At this point, I would bore holes and install the bolts with epoxy formulated for concrete. This is available at a contractor supply house. 2) Yes non shrink grout is strong hold...

I am with a General Contractor based in North Carolina. We recently completed construction of two new dealerships (one Ford, one Chrysler). In both buildings the Design Team specified Sherwin Williams Epoxy. Results have been excellent - very good appearance and durability. A couple of...
