What Is The Purpose Of Underpinning?

All of the foundation technologies we provide, including helical piles, helical micropiles, micropiles, large diameter piles, and driven piles, can be utilized to underpin existing structures. TerraCana has the knowledge and experience to know which technology is the most appropriate for your underpinning project.

  • Prevent settlement and sinking of an existing foundation.
  • Provide support for an existing building or structure during the construction of another.
  • Installation of new foundation inside existing building to support new equipment or buildouts.
  • Building an addition on top of the existing building.

Residential Underpinning Process

01

Consultation

TerraCana works with architects and engineers preparing specifications for new homes. We also offer visual inspections and estimates to homeowners who suspect they have foundation problems. These homeowners are often worried and have many questions. How serious are the warning signs? What are the options for repairing the damage? What costs are involved? How intrusive is the work? Our goal is to remove all mystery from the process, so you can feel reassured knowing that you have a reliable foundation.

02

Design

Once you’ve settled on the right approach for your new construction or repair, TerraCana will do all the design work needed to get started. Our in-house engineering team prepares detailed drawings that include the materials to be used.

03

Installation

When an existing structure has settled or needs additional load capacity, helical piles can be installed with minimal disruption to the building and its occupants. TerraCana installed piles inside a fully operational brewery in Surrey, working within inches of existing equipment without halting production.

04

Repair

Helical piles can be designed around existing underground services. In Queensborough, TerraCana suspended a fibre-optic duct bank from helical piles during foundation pre-loading, protecting sensitive cables while allowing controlled soil settlement beneath.
