Building with Allan Block - In Wall Planters
In wall Planters are a great way to create more usable space and break up
long sections of the wall
Compaction is the most important step when building in wall planters
The lower part of the wall is typically built on solid ground.
But the upper sections are often built on soils that have been disturbed in the construction process.
Building on poor or un-compacted soils will result in the settling of the upper sections of the wall.
To ensure stability these soils should be removed down to solid ground and carefully
reinstalled and compacted
To achieve proper compaction you can remove these soils and replace them
with wall rock or you can use the on-site soils and compact them in 4 in lifts or less.
Good Compaction is key to minimizing settlement over time.
After the base course is in place, lay in four inches of onsite soils and compact
making a minimum of two passes with a mechanical plate compactor
Lay four more inches of onsite soils. Then compact the wall rock and infill soils,
starting at the back of the blocks and working in a path parallel to the wall.
Then place the next course of blocks.
Fill the hollow cores and twelve inches behind the block with wall rock.
Place four inches of on-site soils behind the wall rock and compact.
then add four more inches of on site soils behind the wall rock.
Run the plate compactor over the top of the blocks to compact the wall rock.
Then continue compacting the wall rock and onsite soils in a path parallel to the wall
working from the back of the block to the back of the backfill area.
Continue this process until the desired height of your planter is achieved.
Following the layout on your approved plans, place eight inches of wall rock in
the location of the upper wall section
Add plantable soil to the planter area and on site soils to the remaining backfill area.
Run the plate compactor over the top of the blocks to compact the wall rock.
Then continue compacting the wall rock and onsite soils in a path parallel to the wall
working from the back of the block to the back of the backfill area
making a minimum of two passes with a mechanical plate compactor.
Place the next course of block, turning the wall to follow the layout of the approved plans.
Fill the hollow cores and twelve inches behind the block with wall rock.
Then backfill behind the wall rock using approved on-site soils.
Compact the wall rock and on-site soils behind the block in eight inches lifts or less
Continue adding courses filling and compacting in eight inch lifts to the top of the wall.
On the last course you can choose to fill the block cores and the entire backfill
area with plantable soils to finish off your wall with landscape materials.
Remember to always compact the lower back fill area in four inch lifts or less
and the upper backfill area in eight inch lifts or less. To ensure proper stability
Add in wall planters to your project and fill your landscape with style
