After we have finished the sewage pipes (the filling in of their trenches),
we started with the adjustment to the Earth Tube Mixing Chamber and the Air
Supply Tunnel construction.

The foundation slab is all set and very nicely done!



We managed to get the end segment off the chamber with only having to
destroy one of the concrete blocks. Now we are planning the procedure of
what blocks to go where and what angles to slice certain blocks to form the
downward slope of the tunnel exiting from the mixing chamber etc. etc.

On Monday, we will resume and finish this task and then fill in all the soil
and the remaining hardcore material back in around the chamber and tunnel
and compact it all to build it up to the required level for the main house’s
foundation etc.
