I recently got a call from a landlord who had his yearly inspection for his section 8 tenants. For the first time in all these years the inspector picked on the temporary lally columns. This is a Boston Section 8 apartment and they had to change them.
First of all, what a lally column looks like is a piece of metal that is hollow and it usually has a screw jack on top. Being hollow, it is not as strong. If there is a fire, it can bend on you. The inspectors want solid lally columns. They are metal and filled with concrete, with a thick metal plate on top. They also don't want it just sitting on a 2" or 3" inch cement floor. We have to actually break the floor, dig down, pour a footing, come back and cut the lally column to the right size. We did that, the inspector was happy, and the landlord can continue his section 8 rentals.
Landlords beware, take care of your temporary lally columns. If you need more information, contact A1 Foundation Crack Repair.
