What happens here

The narrator explains a past incident at a car dealership where a retaining wall he built failed due to improper asphalt compaction. He highlights that the wall was constructed vertically (not ideal) and a dual-drum asphalt compactor was used too close behind it, pushing the wall out. Additionally, non-matching blocks and a fence were added later, further compromising the wall's integrity. He emphasizes that these issues arose because the subsequent modifications were not engineered into the original design.

Goal: Illustrate common mistakes in retaining wall construction and subsequent modifications.

Tools and materials

  • Dual-Drum Asphalt Compactor — Compacting asphalt too close to the retaining wall, causing damage (example of misuse)
  • Fence — An addition to the wall that was not engineered
  • Retaining Wall Blocks — The building material of the failed wall
