Building a retaining wall #2 - "How we Base walls"

Watch on YouTube

What happens here

The video accelerates to show the rapid progression of the retaining wall construction. Crews are seen laying subsequent courses of retaining wall blocks, extending the wall's height and length. Concurrently, the integrated precast stairs are being built, interlocking with the wall structure. A skid steer is used to dump 3/4 inch clear gravel behind the newly laid blocks, which is then thoroughly compacted with a plate compactor to ensure stability and proper drainage.

Goal: Build the main structure of the retaining wall and integrate the stair system

Tools and materials

  • 3/4 inch Clear Gravel N/A — Backfilling behind the wall and stairs
  • Dead Blow Hammer — Fine-tuning block placement
  • Levels — Ensuring horizontal and vertical alignment of blocks
  • Plate Compactor Wacker Neuson — Compacting backfill material for stability
  • Precast Steppers Versa — Building the integrated stairs
  • Retaining Wall Blocks Versa — Building up the wall courses
  • Shovels — Manual placement of gravel
  • Skid Steer Loader ASV RT-75 Posi-Track — Transporting and distributing gravel for backfill

worried about it um and then your base material is the same as your backfill your drainage zone three-quarter clear some people use class five but here's the thing this three-quarter clear allows the water to migrate through the base and then this three-quarter clear you can see we've actually got a compactor on it we compact that base material and it can have water flowing straight through it without it ever compromising the integrity of the wall where class five has the fines and although the fines do tend to bind and it doesn't shift or move very often the fines are still there this should have all the fines removed so just the opportunity for the fines to wash out doesn't exist with this another thing that you can do is you can put cement concrete concrete down and put a concrete leveling pad we do not use that for the reason that we just showed you because we need a lot more control over our blocks than what even a screeded off base will allow us to do it doesn't allow us to individually adjust each block to compensate for the height of the wall the amount of grid that may be going in and just to get it dialed absolutely in you can see that the base when you base a wall like this it will take as long for an individual good baser to base as it will be for two or three man crew to backfill up two to three feet tall and compact it [Applause] so let's just watch blaine do one block without saying anything let's just let you guys kind of just take this in uh [Music] yep i do actually i think i had like four while blaine is facing joey is slagging the block off and that's basically just smoothing out the tops pretty close to level looks like it's coming down a little bit
