A solid substrate and well-compacted soils are fundamental to providing a solid foundation upon which concrete structures perform. Over time, Mother Nature takes its toll, especially here in Denver and across the Front Range. Groundwater, erosion, and soil decomposition are the primary source of failure for roads, bridges, sidewalks, driveways, walkways, foundations and other concrete structures.  For sunken flatwork of all kinds Liftech uses an advanced process of injecting a lightweight, high-compressive strength polyurethane, which reacts to form a solid structure in and around voids and areas of wet or loosely compacted soils to strengthen and re-stabilize the substrate and provide a solid, watertight environment.  For cracked, sinking and unstable foundations, Liftech utilizes the best technology available including structural piers, crack sealing and other advanced methods to repair foundations permanently. When you need concrete repair services in Colorado, contact us.

Soils are susceptible to the forces of nature, causing them to contract, expand, and ultimately fail. Without proper support, the concrete sinks, creating not only an aesthetically unappealing environment, but also a hazardous and unstable structure.

Concrete contractors to the rescue! Each failure is unique and requires careful planning to design and implement a concrete repair that will withstand the test of time. We use an advanced process to inject an expandable polymer under the concrete to raise it, and at the same time, stabilize the soil to prevent recurring failure.

The process repairs and eliminates the failing condition within minutes and the concrete is ready to return to service immediately. Drainage and other issues affecting adjacent structures are remedied. The life of the concrete is extended for many more years.
