Our Story

From one man’s commitment to a trusted name

Founded in 2006 by Leo Qu, 51 Excavation began with a simple conviction: excavation done with precision, safety and integrity is the difference between a project that stands and one that settles. What started as one operator’s commitment to quality has grown, project by project, into a company builders and homeowners across the GTA call first when the ground needs to move.

Our mission hasn’t changed since the first job: lay solid foundations for our clients’ dreams with expertise, cutting-edge equipment and an unwavering focus on safety and environmental stewardship. Buildings rise, roads run and landscapes take shape — all of it starts below grade, and that’s where we do our best work.

01 What We Stand For

The values under every job

Expertise

Years in the field and a deep understanding of excavation — soil, water, frost and the machinery that moves them. We know what the ground will do before it does it.

Commitment

Every project, large or small, gets the same promise: exceptional results, honest pricing and a site we're proud to hand over.

Environmental Stewardship

Responsible soil handling, erosion control and proper disposal aren't extras — they're how excavation should be done, and Ontario's rules agree.
