It does not rot
HDPE and galvanised steel in soil contact for fifteen years and counting. Cedar gives you five if you are lucky.
Cut a tote at 18 inches, keep the cage as the frame, drill the drainage, and you have a raised bed that will outlive three wooden ones.

Forklift pockets stay in the cage. Rearranging a garden becomes a ten-minute job.
Drilled sump drainage plus a gravel layer, not a guess about where the water goes.
No new material, no new emissions, and one fewer container in the grinder.
| Layer | Depth | Material | Volume needed | Purpose |
|---|---|---|---|---|
| Drainage sill | 2 in | Washed gravel or expanded clay | ≈ 1.5 cu ft | Keeps roots out of standing water |
| Separator | — | Landscape fabric | 1 sheet | Stops soil migrating into the gravel |
| Growing medium | 14 in | Topsoil and compost, 60/40 | ≈ 9 cu ft | The working layer |
| Mulch | 2 in | Straw, bark or leaf | ≈ 1.5 cu ft | Water retention |
The standard cut is 18 inches deep, holding about 11 cubic feet of fill. That is roughly fourteen 40 lb bags of soil plus a bag of gravel. Cut heights of 12 or 24 inches are available on request.
Yes, within limits. The 4-way forklift entry is kept, so the bed stays movable, but filled with moist soil it weighs about 1,400 lb. You need a forklift or pallet jack to move it.
Nine 3/4 inch holes are drilled through the sump area, and the page recommends a 2 inch washed gravel or expanded clay layer topped with landscape fabric before the soil goes in.
The page expects 15 years or more, since HDPE and galvanised steel hold up in soil contact. It compares that with about five years for cedar, if you are lucky.
