Custom Crete manufactures standard sized M140 U-Blocks, which are used specifically to help create a ring beam around the top of a building.

The Blocks are manufactured with an open ended U shape. When joined together they form a channel. Typically this is filled with steel reinforcing bar and concrete to create a ring beam at the top of the wall.
