About Dynamic

Built on SOLID GROUND.

From residential lots to large commercial sites – Dynamic Excavating brings the expertise to handle it all.

Tested. Trusted. Prepared.​

What We Do

With over 15 years in the construction industry, we have built a reputation for tackling projects that others won’t – or can’t. From routine foundation digs and septic installs to large-scale commercial site servicing, stormwater management systems, and shoreline protection, we handle the full range of civil excavating work across the Niagara Peninsula. No job is too straightforward, and no project is too complex.

What Sets Us Apart

We bring more to the table before a single bucket swings. Dynamic Excavating has a certified engineering technologist on staff – meaning the technical knowledge most contractors outsource is built right into our team. Better designs, fewer surprises on site, and projects that meet code the first time.

Our roots run deep. Owner Mark Heeg grew up on a dairy farm in Haldimand County, where hard work wasn’t optional and taking pride in a job well done was just the standard. That mindset still drives every project we take on today  from a single residential lot to a full commercial development.

We’re not a one-trade shop. We’re the crew you call when the project needs to be done properly.
