| In the picture above we had to use
a wet concrete saw to cut as close to the wall as possible with out
cutting into the concrete wall or the electrical. After that we jack
hammered out the old concrete floor slab on both sides of the wall and
removed what we could of the floor. Then we dug out the dirt per
engineering specifications. The next step would be to install the hold
down anchor bolts and then pour the new concrete giving us a new
structural footing.
This process is common when installing a second floor addition. There
were two reasons for this new footing. One was to create a shear wall
hold down and the other was so we could install a weight bearing post
for the up stair floor.
