Fill er Up

Here we are trying to fill one of the holes with concrete.  I’m holding a piece of plywood so it will stay in the hole until it dries.  The idea was to blow the concrete to the back of the hole and force the water out.  The shotcrete has more cement in it and less aggregate.  So, it dries quicker and is harder when it dries.  A normal garage floor is 3000 to 4000 lb concrete … this is around 8500 lb concrete.  The biggest hole took 4 yards of concrete to fill.  At $125.00 per yard that was one expensive hole ! ! !  You can see Dave in the background wire tying the metal together.
