Don't mind the natural habitat underneath. It won't affect that at all. Most canals in southern California that are dry so not soak water up quick, so that would be disaster if heavy rains came in. Unless it's reinforced as a matha funka.

That's a rigged falling lol.

Also, most blocks on the pyramids we're built by mixing materials on site, pouring them into forms and stacking them next to each other. Geopolymers.
