About

A family owned crew, based in Nampa, Idaho

Poly Flow is owned and operated by Pat Sweeney and his family, based in Nampa, Idaho. It is a concrete lifting, foundation repair, and geotechnical contractor serving the Treasure Valley, and the work runs from driveways and shop floors to dams, cisterns, and grain silos.

We built the company on one habit: test before you quote. Penetrometer readings tell us what is under the slab, so you get the repair that holds and skip the one that will not.

Estimates are free and done on site. We test the soil before we quote, so the price reflects the actual problem.
