Leaky Roof, Earth Tubes, and DIRT

We have been very concerned about the leaky roof on our house.  It is not good to start out with leaks.   Dan and his crew came out and sprayed two coats of Vandex Cemelast on the lower about 10 ft of the structure.  We borrowed a heater (thank you, Junius) and heated the interior of the house, using plastic to cover any window and door opening where they were not installed.  After a few days, we water tested and found that we still had the same leaks in the lower part of the house.  More thinking....
Dan and his crew came back and brushed the waterproofing on, paying special attention to the areas that leaked.  More thinking....
Dan and his crew came back and watered down the waterproofing material and poured and brushed it over the surface.  
I have to tell you the surface of a shotcrete structure is no where near smooth.  It has craters and mountains resembling a miniature surface of the moon, because the shotcrete is mortar with stone mixed in it and the stones are of sizes up to a small egg (pullet).  I think the only qualification for the size is that it must fit thru the nozzle. Bill says there is some kind of sifter at the beginning of the hose that the stone has to fit thru.  And the shotcrete comes out of the nozzle with such force that if a pebble is the last to hit that surface area, it usually forms a crater.  Or, if it hits another stone on the surface, it may form a mountain.

 Before hose testing, since no rain was in the forecast, I took many pictures of the interior of the house.  Then, I put a sprinkler on the West Annex.  It stayed there for about an hour.  Then I went out and took the sprinkler off and put the nozzle back on and sprayed the house from the crown of the house.  And then I went to ground level and sprayed from there.  We still have leaks but fewer.  
It rained, I think it was perhaps two weeks ago, and showed some leaks that my 'watering' did not show, and it was not a hard rain, and the leaks were worse than my test found, if one can rank leaks.  So, we are addressing them. We are applying waterproofing 'piecemeal' to the structure in what looks like a wild applique pattern.
Along with the leaks on the structure, we are digging up the yard.  We are reinstalling the french drains, as we moved them for the shotcrete process, and the waterproofing process.  So we are putting them in place, covering with stone and filter cloth. AND, DIRT! Yes! We have started to backfill - of course, where there are no leaks.
The garage is almost completely covered in dirt.
 
The east side of the house, where the tunnel (actually food pantry/wine cellar) is, the tunnel is almost covered. Our home now has many tones of gray which is the waterproofing material.

 The west side is awaiting some leak-fixing. We started backfilling and realized there were leaks and stopped.  This picture shows the southwest area around the structure with a higher ground.  The blueboard that you see, is just that - closed cell insulation.









Also, the earth tubes on the West Annex and the tunnel are being connected and the east ones are being buried.  The west ones are waiting for the backfill in that area.
Our dirt mountains are starting to crumble, and some disappeared, and then reappear and disappear again as the excavator digs the ditch for the earth tubes.
A window technician came out and checked out our window installation.  We have some problems which they are addressing with the manufacturer.  And he will be back perhaps before Christmas or the New Year.
