About us

AVERTEX is a diversified underground utility contractor led by Jack Kottelenberg and Andy Blokker and other members of management. We have been in operation since 2003, with many of the management team and foremen having been in the industry since the early 1980s.

We pride ourselves on working with our clients and stakeholders to achieve the project goals. With our collaborative efforts and experience, we have been able to complete projects across Canada ranging from tens of thousands to tens of millions of dollars.

The backbone of our company is the installation of private and public utility networks. Our grass roots lie in the power (hydro utility) and telecommunications sectors, however over the years we have grown to cover a wider range of utilities including water, sewer, railroad utilities, site servicing and renewable energy. Within these sectors work is completed employing a wide range of installation techniques, although we specialize in projects involving trenchless construction such as horizontal directional drilling, plowing, guided boring and/or pipe bursting.

With our head office in Orangeville and a regional office in Smithville, we focus on projects throughout Ontario but also perform work in other provinces across Canada on a project specific basis.


With thanks to our dedicated and experienced employees AVERTEX is proud of its ever-growing list of diverse and complex projects in both the public and private sectors.
