Alternative Foundation

Who We Are

The Triodetic foundation consists of an engineered steel or aluminum rigid platform which sits on the top of the soil itself and keeps the building level and straight regardless of soil heaving and settling due to frost or sinking. Unlike piles or screw jacks, which always move and shift over time causing structural damage, the Triodetic foundations never allow damage to the integrity of the building and never require maintenance.

Why Choose Us?

  • Cost competitive
  • Quick assembly, no welding
  • Pre-engineered building plan
  • Durable steel & aluminum
  • Frame easily modified
  • New or existing buildings
  • Anchored against winds
  • Uniformly supports
