Hand-Dug Shoring & Underpinning

About the project

Scope of work

  • Hand excavation
  • Temporary shoring
  • Sequential underpinning
  • New footing sections
  • Structural monitoring

Some excavation you do with a 20-ton machine. Some you do with a shovel, a plan, and a lot of patience. Here we removed material by hand to shore up and underpin an existing foundation — sequenced in small sections so the structure above never knew we were there.

Underpinning is the highest-stakes work we do: it demands engineering, careful shoring, and crews who understand exactly why the sequence matters. It's also where experience shows the most.
