Our Story

Stable Ground, an arm of The Underpinners Inc, is a Toronto-based company specializing in deep foundation work. Since The Underpinners’ inception in 2011, the majority of projects have been in complex and difficult to access locations in Downtown Toronto. While the complexity of project was manageable, the team soon realized that in order to effectively execute, elaborate soil retention (shoring) for deep foundation work was required for safe excavation of these projects.

Seeing that this highly specialized service was in great demand within the Downtown Toronto market, the company purchased its first limited access drilling rigs and various other powerful – but small - types of machinery required to manage the diverse geographical terrain (rocks, water, fill material) in Toronto.

It was at this time that Stable Ground was created.

Today, Stable Ground has a sizable inventory of powerful excavators, skid steers, drills, tooling and versatile attachments necessary to access both small and limited access spaces as well as larger projects. The team is supported by a team of experts across geotechnical, structural and civil engineering.
