Concrete support columns
Posted: Fri Apr 25, 2014 2:41 am
We are doing concrete restoration here in Southern Florida. Our Condo has a covered carport for the owners. The structure is a simple 4 inch thick concrete roof supported by 12 inch diameter concrete columns with rebar. A number of the columns have damage and the company doing the restoration work has removed 1/2 of the diameter of the column due to concrete problems. They have added temporary support columns while they are doing the work. This is not the entire length of the column but 2-3 feet above ground. They have a a number of BASF N-425 premixed mortar bags on site. Is this the correct material for the columns? I ask because BASF calls this a lightweight material. thank you
