A concrete masonry unit (CMU) is a standard size rectangular block used in building construction. Those that use cinders (fly ash or bottom ash) are called cinder blocks in the United States, breeze blocks (breeze is a synonym of ash) in the United Kingdom, and hollow blocks in the Philippines.

Secondly, what does a cinder block look like? Cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders which find use in construction sites. Concrete blocks often, on the other hand, are flattened constructs made of steel, wood or cement.

How do you waterproof a concrete block wall?

How to Waterproof a Cinderblock Wall

Introduction. Ensure That Wall Is Clean and Dry. Scrape off any peeling paint and sweep down walls to remove dirt or debris.
Patch Holes. Patch any holes in the wall with expanding hydraulic cement. Allow cement to dry for 24 hours.

Apply concrete to any gaps in the blocks or mortar using a shovel. Fill the holes and cracks as deeply as you can, then scrape the top over with a trowel so the concrete can patch the wall together evenly.

How many cinder block do I need?

Multiply the total wall area by 1.125 to get the approximate number of blocks you'll need to build the garage walls. Multiplying 700 square feet of wall area by 1.125 is 788, meaning you will need around 788 concrete blocks to build your garage walls.
