text:  We are locally owned and based out of Nampa. We have only 5 star Google reviews. Polyflow is the best choice if you have uneven or cracked concrete. Uneven concrete causes annoying trip hazards that can result in costly injuries to your friends and family. We lift sidewalks, driveways, patios, pillars and more. We also fix deep soil that has lost its compaction with our geotechnical services.
