```									                 Introduction to the Meyer Lok-Block Mortarless System
There are three main components to the Meyer Lok-Block system: line block, male corner and the
female corner.

The male and female half blocks can be made from corner blocks see Fig. 2.

How to calculate the number of blocks required for your project.
First: determine the length and height of each wall in feet.

Example: 32' x 60' crawl space, 5'4" high.

Second: multiply each length by 12" and divide by 16" to determine the number of blocks in each row.
Note: If the number of blocks results in a whole number refer to option “A” in Fig 3 for block layout.

Example: 32' x 12" ÷ 16" = 24 and 60' x 12" ÷ 16" = 45 you would use option “A”.

If the width was 30'

Example: 30' x 12" = 360" ÷ 16" = 22.5 blocks you would use option “B”.

Third: Taking your height in inches (64”) and dividing it by 8" (height of block) to determine the
number of courses. In this example (8)

To determine the total number of blocks needed per coarse add the numbers of blocks for each side to
give you the amount of blocks you’ll need for each course.

Example: 24 + 24 + 45 + 45 = 138 blocks per course.

Multiply the blocks per coarse by the number of courses to determine the grand total

Example: 138 x 8 = 1104 blocks.

Because each coarse in this example has four corner block, it is necessary to subtract the number of
corners from the grand total to determine how many line blocks and how many corner blocks are
needed.

Example: 8(courses) x 4 (corners) = 32, 1104 blocks -32 corners = 1072 line blocks.

The required number of blocks needed is as follows:

1072 line blocks and 32 corner blocks (the type of corner blocks will be determined by the layout). For
this example you would need 16 male and 16 female corners.

required

Note: not drawn to scale; for
demonstration only.

Option “A”
Full Block Total

(4) Full Blocks

Example: 32’x 12”inches ÷ 16”inches = 24 full blocks

.

Option “A”
Option “B”
Full Block Total
Option “B”
½ Block Total

3 ½ Blocks
(4) Full Blocks

Example: 30’x 12”inches ÷ 16”inches = 22 ½ blocks.

Installation of Meyer Lok-Block
After you have placed your footings, it is time to mortar your first course of block to the footing. This is
done to level the block.

NOTE: It is crucial that the first course be square and level.

When laying your courses all the male ends will be running in the same direction. (See Fig 4)

The next course the male end will be run in the opposite direction from the previous course. This pattern
will continue until you reach the last course.

Between laying courses make sure the top of the blocks are free of debris.

When reaching your top course you’ll stay with the direction of the pattern you’re running, but the block
will be turned upside down. This will provide a flat surface to receive the sill plate.

Note: When reversing the direction of block for each alternating row the corner blocks must be
turned over maintaining male corners at male corners and female corners at female corners.
