Gridor Construction, Inc.

For the last 40 plus years, Gridor Construction has focused their efforts on the improvement of water and wastewater treatment facilities.

Since 1969, we have completed hundreds of municipal and private projects throughout the upper Midwest. Gridor’s scope of work ranges from one-day repair projects to long-term construction of new facilities.

As a general contractor, we take pride in delivering a complete project to our clients and their design team. There is no step of the construction process, from ground breaking to final start up, that is not examined by our project team to make for an efficient and well-built project.

We successfully perform and are involved in projects requiring: deep excavation, dewatering, sheeting, caisson construction, bypass pumping, site utilities, jacking/boring, heavy concrete work, precast erection, process equipment and process piping installation.
