Concrete contractor, Concrete Lifting & Raising, Foundation Repair, Soil Stabilization & Void Filling. Polyflow is a family-owned concrete lifting and geotechnical contractor based in Nampa, Idaho, serving the entire Treasure Valley including Boise, Meridian, Caldwell, Eagle, Kuna, and Star. We raise sunken and uneven concrete: driveways, sidewalks, patios, garage floors, and shop floors. We us high-density polyurethane foam, with most residential jobs finished in a single visit. We also repair foundations, stabilize weak and poorly compacted soil to increase load-bearing capacity, and seal cracks, joints, and surfaces to protect the sub-base from erosion. Unlike contractors who quote from a quick look, we use penetrometer testing to measure the soil before we recommend a repair. Every lift is backed by a 5-year no-settle guarantee.
