On April 20 and 21 we finally able to place the concrete floors after what seemed like a long winter.  In the attached photo you see Tony Periat from Bowser Morner testing the quality of the concrete.  As the floors are being placed Tony takes periodic samples of the concrete and makes 6″ cylinders which are cured and then compression tested after 7 days and 28 days to assure the concrete reaches the 4000 psi strength.
