The author found this product to be the best retaining wall system which adds great value to any property that carries it. 

Bestcrete had two options 

• Allan Block 
• Jumbo Junior Allan Block.

Note this is an Engineering product and for large Walls you should consult the professional engineer.

TNTDIYCONSTRUCTION would discuss the installation of a small wall 3' height and 12' in length, or a planter.

Note:  The Task involves excavation, heavy lifting and requires industrial tools, e.g. 12” Plate compactor and concrete cutting disc. The Allan Block is sometimes referred to as the AB Stone.  

 

 

Note:  Geo fabric and drainage pipe are not required for short walls.

Step 1 

Measure the length of the wall and the approximate height of the wall by using the estimating table to the right in calculating your block requirement.

Step 2

Mark out the area in which the proposed wall is going. With the shovel or spade remove the soil 8" deep by 12" width by the length of the wall.

Step 3

Run the Plate Compactor in the new trench and cut or fill to ensure the base is level or graded. Measuring the level or grade should be done with a line or laser levelling device.

Step 4

Fill in 3/8" aggregate / gravel into trench and run the Plate Compactor to ensure the base is level.

Step 5 

Place the AB Stones into trench remember that the weight of  each block is 80 lbs, levelling the block is very important at this stage. Also ensure a consistant flow on the front of wall.

Step 6 
Fill the AB Stone and around the block and trench with 3/8" aggregate / gravel then run Plate Compactor around the block. Also ensure a consistant flow on the front of wall and levelling of the first row.

Step 7
Continue stacking AB Stone and filling block with 3/8" aggregate / gravel. Remember to run Plate Compactor behind block, checking level with each block installed.
Step 8 
You have come to the end of this task, and you can place the AB Stone Caps giving your wall a finished look.
