We beat the Rain!
After a successful dig and inspection, we got ready for the pour first thing Wednesday morning. The calculation for concrete is generally very accurate....measure the avg length x width x height and you get cubic yards to order. The trucks can hold 10 yards but it is better to bring no more than 7 to minimize stress on the roads etc....so two trucks for 11 yards. It has become the standard to use a pump truck to take the concrete from the truck and pass it through a pump which allows the pump guys to walk around (not that easy) and drag the hose and fill the holes.....much easier than doing it by the wheel barrel! They charge $75/hr plus $4 per yard....and the mix is made special for the pumping. The pump went easy. We follow them around with a rake or hoe and pat down the top of the concrete to help level it and check it is to the top of the steel pegs that set the correct depth and level (the level is the important thing)....THEN when it's done (4 hours or so) it can rain ...and so it did. Tomorrow it will be set up enough to restring and mark the corners with nails....those marks will be what the mason uses to start his corners...Tomorrow the block is delivered and then the mason will do his work.
