Install Base Course

Document imprimable.pdf

  • Begin the base course at the lowest wall elevation For more information on stepping up the base course , Click here.

  • Place all blocks with the raised front lip facing up and forward on the base material near the front of the base trench.
  • Check and adjust each block for level and alignment as it is installed. Check the blocks for level frequently from side-to-side and front-to-back. Verify the proper position of all the AB blocks by examining a string line across the back of the blocks or by sighting down the back of the raised front lip.
  • Make minor adjustments by tapping the AB blocks with a dead blow hammer or by placing up to 0.5 in. (13 mm) of coarse sand under the blocks.
  • Irregularities in the base course become larger as the wall stacks up. Careful attention to a straight and level base course will ensure a quality finished wall.

Backfilling and Compaction

  • Fill in the area in front of the blocks with on-site soils. This will keep the base course blocks from shifting while filling and compacting.
  • Fill the hollow cores of the base course and 12 in. (300 mm) behind the block with wall rock to the height of the block.
  • Use infill or approved onsite soils to backfill behind the wall rock in lifts of no more than 8 in. (200 mm).
  • Use a plate compactor to consolidate the wall rock directly behind the block then compact in a path parallel to the wall, working from the back of the block to the back of the excavated area with a minimum of 2 passes. For additional details on compaction, Click here
  • Check the base course for level and adjust as necessary.
  • Every course after the first course requires compaction starting on the block.

Additional Courses

  • Remove all excess material from the top surface of all blocks. This prepares a clean, smooth surface for placement of the next course.
  • If reinforcement is needed . click here to continue the installation process
  • Stack the next course of blocks so that the vertical seams are offset from the blocks below by at least 1/4 the length of the block.

    décalez les blocs d'au moins 1/4 par rapport à la longueur du bloc
  • Check each block for level and alignment and make adjustments as needed.
  • Fill the hollow cores and 12 in. (300 mm) behind the block with wall rock to the height of the block
  • Use infill or approved onsite soils to backfill behind the wall rock in lifts of no more than 8 in. (200 mm).
  • From the 2nd course and above use a plate compactor to compact directly on the blocks as well as the area behind the blocks. Compact in lifts of 8 in. (200 mm) or less.
  • Repeating these steps, complete the wall to the desired height. On the last course, fill behind the blocks with organic soils in place of infill or approved on-site soils. This will assist in any plantings above the wall and also to direct water from running behind the blocks.
