@NoBoDe - I applaud and respect anyone who is as creative as this guy - I had a husband like that, who could always devise less costly solutions which worked just as well as more expensive ones.
The Romans made cement from volcanic dust, lime, gypsum and include bricks and rocks to make foundations, walls etc.
I wonder how long it took this guy to build his shelter - would have been quicker from wood. I had a great 'Mother's Day' - was paid due homage Tau
