...another sweaty day in paradise. Overcast and cloudy is a welcome blessing. We laid in the rebar for pour #2, tied the bars, and propped up the mat on bar chairs. - - Continuous, multiple pours above grade are typically separated at the smooth-dowel seams with expansion joint. I conferred with a trusted friend and concrete contractor and he dismissed expansion joint as unnecessary for such a low-tech, underwater application. He did insist, though, on doweling the slabs together. - - This is gonna be another pretty thick pour. Since I don't want to lose too much slope, as it is already lower than ideal, we are keeping the top end of the pour as high as practical. That, and the edges of this pour, like the first, drop off to create thicker edges. I'm guestimating 9 yards on this one.
