Upper Keswick, NB

We added a sun porch to our home several years ago and we had 4×4 posts wrapped in styra-foam, below frost line and sitting on patio slabs. The first couple years we were okay so we started to finish the outside. That winter the walls cracked around the windows, walls started coming away from original house and the door wouldn’t even close. Frost was the culprit.

In the spring we dug it up, cut off the posts and installed jack posts supposedly so we could adjust them when winter came. This didn’t work and we had the same problems as the previous winter. I was lamenting about the problem at work and a solution appeared. A co-worker suggested the Footing Tube, a new product on the market. We used it that spring and we have had them under the porch for 2 winters with no problems. I would recommend this footing tube to anyone who has a deck or sun porch which could be affected by frost movement.
