Caissons and Grade Beams

Reinforce your foundation from the ground up with caissons and grade beams engineered for maximum strength, stability, and long-term structural performance.

Overview

Caissons & Grade Beam Foundation Solutions

Caissons and grade beams are advanced foundation systems designed to support structures in areas with unstable, weak, or shifting soil. These systems work together to transfer the weight of a building to deeper, more stable layers of soil or bedrock—ensuring long-term structural integrity.

Caissons (also known as drilled piers) are deep, reinforced concrete columns installed by drilling into the ground and filling the shaft with concrete. They provide strong vertical support by anchoring structures to stable soil layers below the surface.

Signs You May Need Caissons & Grade Beams

Foundation issues often indicate that your structure is not adequately supported by the existing soil conditions.

  • Foundation Cracks - Visible cracks in walls or foundation indicate movement below.
  • Uneven or Sloping Floors - Shifting support beneath the structure.
  • Doors & Windows Not Closing Properly - Frame misalignment caused by foundation movement.
  • Soil Instability or Expansive Soil - Common in areas with clay or poor load-bearing soil.
  • Previous Foundation Repairs Failing - Temporary fixes may not address deep structural issues.
  • New Construction on Challenging Soil - Requires deep foundation support from the start.

Frequently Asked Questions

A deep concrete foundation element that transfers structural loads to stable soil or rock.

A reinforced beam that connects foundation supports and distributes weight across them.

When soil near the surface is too weak to support a structure.

They are more effective in unstable or expansive soil conditions.

They work differently—spanning between supports instead of bearing directly on soil.

Depends on project size and soil conditions.
