When ordering the concrete we specified that we needed a conveyor, so that we could reach as many of the perimeter footings and as much of the holes in the concrete block walls as possible. We anticipated this being a slow tedious process, and had a trailer ready to take a load of concrete to fill some of the walls by hand. But we really lucked out.
The concrete truck driver/operator ended up being a friend of Pat's from his home town! He ended up spending over 2 hours methodically placing small amounts of concrete exactly where we needed it. Pat was even able to leave the site to go to most of his daughter's 2nd birthday party.
Pat made this hopper, with removable sections, that made the filling of the holes in the concrete block wall very easy and clean.
All of the holes in the wall that had rebar were filled with concrete to create vertical posts/beams within the wall. This strengthened the cross fin walls that carry most of the lateral wind loads in the two houses. We also filled holes points ever 900mm along the long walls, into which we inserted threaded rods with washers welded to the ends which were spaced in pre-drilled bearing plates.
Once set, we will remove the bearing plate, and put on a damp-proof course between the blocks and the wood. The ground floor structure will be bolted to the foundation wall.
