i would think adobe construction will work in the d.r. rammed earth construction type of cheap building that is grass roots...long lasting and better (cooler)..temp wise...
of course dom's want tolive in a concrete surround..
My dad was doing adobe construction in the DR some 40 years ago with Peace Corps. It was rejected outright by the Dominicans~ anything made of "mud" was for the poorest campesinos, regardless if it was made into bricks or what it looked like finished. I told Hillbilly about it and he mentioned the same issue with his projects at the time.
I was just a kid, but remember the brick forms and the crew cranking out a couple hundred bricks an hour.
Cinder blocks are cheap and sometimes donated by the government. They're the preferred material. If it ain't broke, don't fix it..
Making bricks.. took a couple times before I noticed the wire for trimming the excess.
