What happens here

After demolition, prepare the base for the retaining wall. First, compact the existing sub-base thoroughly using a vibratory plate compactor (Tomahawk). Next, spread a layer of screening sand (Class 5 or similar granular material) over the compacted sub-base. Use a custom-made 'screed-o-matic' (a notched wooden bar) to level the screening sand to the correct height and slope, ensuring a uniform and solid foundation for the first course of blocks. Lay the first course of Versa-Lok retaining wall blocks directly onto the leveled sand, followed by the first layer of geo-grid material to provide structural stability.

Goal: Create a level and stable compacted base for the retaining wall.

Tools and materials

  • Geo-grid — Providing structural reinforcement and tying blocks together
  • Screed Bar — Leveling the screening sand
  • Vibratory Plate Compactor Tomahawk — Compacting the sub-base and fill material
  • Screening Sand — Leveling base layer

okay so this is going to be a raised patio that our base is super nice and level so we got the screed-o-matic 5000 that's how sam talks 24 7. screed-o-medic 5000. so we've got a couple different ways of building this raised patio now what we're actually going to be doing is using fill compacting it and i'm going to show you something pretty cool here in just a moment i cut a notch out of our screed-o-matic so that it'll sit where it needs to set on the blocks all right our base is all in get our first course of geo grid in and then so the next step we're gonna put another course of black in fill it up with class five pack the heck out of it it'll be another layer of geo grid we'll do one more chorus of the blocks pack the hell out of it and then we'll be sanding pavers on top of that this notch in the back is dead middle
