Are cinder blocks load bearing?
Today, the lighter cinder blocks are used in walls in large construction projects where their weight is a bonus, and they don’t have to carry any load.
Why do cinder blocks have holes?
The openings are called “cells” and one reason they are there is because they make the blocks lighter and easier for a mason to handle. But the primary purpose of the cells is that they align from top to bottom of the wall when laid, and enable a builder to fill some cells with grout/concrete to strengthen the wall.
Is it safe to put a car on cinder blocks?
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.
