Site preparation
Before you start, make sure the quality of the level, the square and the alignment of the base that will receive your walls.
Osblock can take a 1/8” variant. The correction will happen by itself at the 3rd row of blocks. If the level of the base exceeds 1/8’’, you will have to correct under the starting rail.
This step is very important for the smooth running of your installation.
Calculate wall height
The total wall height depends on the number of Osblock™ you are stacking. Here is a chart of the final wall height.
Please note that every walls that will not correspond to those measurements must be raised at the base or head of the wall with materials such as 2×6 framing wood.
