Dig some stones out of a hole. This hole will be used to make an underground dome water tank. Some parts of my land has this rock a meter down.
Then you get a pile of rock. These are not the greatest, too roundish, but what i have. Costs me about $6 per m2
Elia is a mason we brought in to speed things up. He did this wall. he gets better as we go left.
As requested some side shots.
