Structural Underpinning is the process used to strengthen or stabilize structures by extending the depth or breath of the foundation so that the structure rests on a stable stratum or distributes the load across a larger area.

Structural steel underpinning uses steel to stabilize foundations for the following reasons:

  • Strength – The original foundation is not strong enough to support its structure
  • Change – The use of the structure has changed
  •  Soil – The properties of the soil have changed or were miscategorized to begin with
  • Construction – Additional construction to the structure requires a stronger foundation or new structures added around existing structure
  • Economical – It’s cheaper to repair the existing foundation versus making a new one

When structures show signs of foundation damage, but before attempting DIY foundation repair, it’s important to have a foundation repair specialist test the soil and inspect the damage to determine the best course of action.
