CHANCE® Helical Underpinning
Restoring Stability from the Ground Up

MaurerCo Retaining Walls installs the CHANCE® Helical Underpinning system, distributed by Foundation Technologies and engineered by Hubbell Power Systems. This solution is designed for structures that have experienced settlement, cracking, or shifting due to inadequate foundational soils or dynamic loading.

How It Works

Underpinning with CHANCE® helical elements involves installing high-capacity piles or piers independent of the existing foundation to depths beyond problematic soil strata. Each element is torque-monitored during installation, and once it reaches the required capacity, it’s bracketed to the existing structure. The load is then transferred from the failing foundation into reliable soil layers below.

Key Benefits

  • Limited-access installation: Suitable for basements, crawlspaces, or confined areas.
  • Immediate loading: Once installed and connected, the structure load may be applied immediately with no lengthy cure times.
  • Minimal disruption: Low vibration, minimal spoil removal, and smaller equipment make this ideal for occupied buildings or sensitive sites.
  • Engineered capacity: Systems are designed based on soil and structural conditions, ensuring a tailored solution for each project.

When to Consider Underpinning

  • Foundations showing signs of settlement, such as cracks in walls or floors, or doors/windows sticking.
  • Structures built over weak soils, fill, or with water intrusion risks.
  • Renovation or addition projects where existing foundations require increased load capacity.
  • Retaining walls or earth-retaining systems that require reinforcement from below.
