Concrete work at the barn

Our barn is over a hundred years old and needed some work to help it last for a few more years. This barn had been built in a couple of different stages over several years with reclaimed beams from other barns. The support posts of the barn had been placed on large, flat rocks, placed on dirt (hard-pan). A concrete floor was added later but poured around the support posts leaving the bottom of the posts embedded in dirt. Over the years the bases of some the support posts started to rot.



We want to fix the old floor of the barn but first need to re-set the supports on a solid base. We got a couple of 20 ton jacks and raised the barn enough to remove the old post. We then removed old concrete floor, dirt and rock until we found a solid spot to pour a new concrete footer with re-bar. Once the wide base was in place we poured a new concrete extension above the floor line for the post to set on. The bottom of the old support post was cut off to the correct length and the rot removed. The post is then reinstalled (level and square) and bolted to the new concrete base.



Another part of this project required the installation of a new retaining wall on the south side of the barn to replace an old section of the stone support wall that had fallen due to frost movement. We started by removing the dirt and rock from the old wall section. A 6 inch thick base of concrete with re-bar was poured to form a level platform to build the new wall on. We then poured a 5 inch high section of the new wall to form a "key" to hold the forms for the new wall.



Once the "key" was ready more re-bar was installed and the concrete forms for the bottom section of the wall were attached to the "key".


The bottom section of the wall is 32 inches high, 8 feet long and 10 inches wide. We mixed 11 batches of concrete in our mixer and completed this pour in a couple of hours.



Once the bottom section cured we removed the forms and moved them up for the top section of the wall and clamped the form in place. This section only required 8 mixer loads and was completed in less than two hours.
