Remember to stack the blocks so that the vertical joints stager.
How to build a dry stack concrete block wall.
It s called drystack block and it can be laid up as easily as the plastic toy blocks in a lego set.
A dry stacked stem wall without using any mortar or cement should be no taller than 9 feet 2 7 m and can support a small shed or similar light structure.
Since blocks can vary slightly you may need an ocassional shim cut from aluminum flashing.

With some dry stack methods conventional concrete blocks are simply stacked and then locked into place by a coating of fiber reinforced surface bonding concrete sbc that is applied to both the inside and outside of the walls.
High regular blocks are an inexact 3 8 in.
Once the first course is set dry stack the remaining block in a running bond pattern to the desired height all corners should use an interlocking pattern.

Check each course for level as you proceed.
The first row on the foundation is set in mortar and very accurately leveled but with no mortar between the blocks.
Less in each direction to allow for the mortar joint.
Some dry stack systems use interlocking blocks that are easily assembled horizontally in an offset method.
I am pretty sure that rebar and concrete fill was also required at set distances along the wall length.
Before applying the surface bonding cement dampen the surface of the block.
Step 7 thoroughly dampen the block wall with water dry block will draw the water from the mix making it difficult to finish and can cause inconsistent color and cracking especially in.
This is what ties the whole stack of blocks together.
