Liftech specializes in lifting, leveling, stabilizing and repairing all types of concrete flatwork and foundations in residential, commercial and municipal applications. For flatwork lifting and leveling, we use an advanced process of injecting a light weight, expanding polyurethane foam to raise, level, and stabilize concrete at a fraction of the cost of replacement. Unlike the traditional mudjacking, Liftech uses a minimally invasive and permanent solution to repairing flatwork of any kind. 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. Liftech also resurfaces, seals and installs new concrete. We are proud, accredited members of Home Advisor, The Better Business Bureau, Angie's List and Yelp! with more A+ and 5 Star ratings than any other local company in our sector.

"Jason and Cody were very knowledgeable and answered all my questions. They raised the driveway, front steps, and patio; the end results were excellent! I definitely recommend Liftech."

"We hired Groundworks to install a sump pump, expecting professional work and peace of mind. Unfortunately, the experience was anything but that. First, the team showed up 2 weeks after the initial visit. Worse than the delay was the complete lack of communication throughout the process ? getting updates or even basic responses was frustratingly difficult. The biggest issue, however, was the quality of the work. Their installation was poorly executed, and we ended up having to hire another company to fix their mistake ? costing us even more money on top of what we already paid Groundworks. We trusted them with an important job in our home and feel completely let down. I would not recommend Groundworks to anyone looking for reliable, professional service."

Foundation Repair questions, answered by experts

Underpinning is a type of foundation repair in which a repair specialist installs piers under your foundation to provide additional support for the concrete and structure above. Foundation repair is an umbrella term that includes many other repair methods, including foundation crack repair, waterproofing, cosmetic repair, concrete block wall stabilization, and more.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

Cracks, spalling, uneven surfaces, and weather damage often necessitate professional repair or resurfacing.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
