How I square a building (Part 1 of 2) Mike Haduck, footer & block

I show an old school way to square a building, starting with the concrete footer to the beginning of the block work. I use a home made plywood square to get a ballpark idea of square and use it again to double check at the end, All my videos are my ways and Ideas, I always suggest anyone doing any type of work to consult professional help. https://www.amazon.com/shop/mikehaduck
