Why are houses in Florida built with cinder blocks?
The benefits of concrete block house construction make concrete a smart material choice for building in Florida. Concrete block houses are energy-efficient, fire-resistant, noise-reducing, pest-resistant, low-maintenance, and healthy. Concrete homes are also a good investment.
Will cinder blocks hold up a car?
The only appropriate place to jack up a car is on pavement. And in our case pavement means concrete, not softer asphalt. Concrete block is not acceptable, because it’s far too frangible. There are really only three options: ramps, old-school jack stands and, of course, a hydraulic lift.
