Incorrectly Installed Lally Column Wakes Homeowner at Night- Boston, MA

Joseph Coupal - Friday, June 03, 2016

We got a frantic call about 2 weeks ago during the heavy rain. It came in at about 6:00am or 7:00am. The homeowner heard what he described as a “sonic boom.” He ran into the basement and found a floor crack that he had never seen before. It ran right off the Lally Column. The Lally Column was not placed on a footing, which is a deep piece of poured concrete that it is supposed to sit on. When it is not on a footing and there is a lot of hydro-static pressure from water going underneath the floor, the Lally Column moves. This is what caused the crack in the concrete floor and the sonic boom. Lally Columns hold your house up.

So, the first thing you want to do to ensure your Lally Column is secure is to look and see if they are level. If they are not, they are not supporting as they should. Then, be sure they are set on a footing.  Lally Column that are put on a cement floor with no footing  are not holding much. You can test this by tapping on the floor to see if it sounds hollow.
