Concrete Leveling at Denver Gas Company

Polyjacking Helps Anadarko Petroleum

Anadarko Petroleum operates six hydraulic fracturing stations on the Wattenberg Gas Field located beneath the states of Colorado and Wyoming. When an inlet pipe broke recently at its station just north of Denver, CO, injection fluid drained beneath the concrete slab at the station. This caused 3- to 5-inch voids to form under the concrete floor which left the concrete floor unlevel. The general contractor of their onsite service company, Open Range Services (ORS), knew he needed to find an efficient and effective solution for lifting and leveling the sinking concrete slab.

Why Mudjacking Wasn’t a Good Option

At first, the head of Open Range Services considered using the “tried and true” method of concrete leveling, mudjacking. Mudjacking forces a mixture of concrete and other aggregates beneath concrete slabs in order to lift and level them. After some consideration, he found that mudjacking would not only be too expensive, but that it would take a lot longer to apply. In addition, ORS would have the added cost of removing and replacing the entire slab instead of simply repairing it.

Why Polyjacking Is Best for Concrete Leveling

When ORS contacted Polyjacking.com about their concrete leveling process, it soon became clear that polyjacking was a superior solution for their situation. Steve Walker, general foreman for Pro Foundation Technology, Polyjacking.com’s parent company, shares:

“[Polyjacking is] a far superior method. Mudjacking means you drill large holes in the slab, mix the mud or grout onsite, and pump it using large hoses into the holes in the slab. It’s dirty, invasive, and time-consuming. Geotechnical polyurethane foam is much lighter- four pounds per cubic yard, versus 120 pounds or more using mud – simpler, cleaner to use, and much less expensive. We pump a two-part liquid system from a truck or pull-behind rig through a narrow hose into a gun used to inject the unique geotechnical foam beneath the slab to fill any and all voids. The foam expands, completely fills the empty space, raises the slab to level, then cures in place to become highly durable and [help] prevent further erosion at that site.”

Polyjacking is Easier and Faster to Install

Polyjacking.com uses a compound called TerraThane to inject beneath concrete slabs for lifting and leveling. TerraThane is manufactured by NCFI Polyurethanes, a Fort Worth, TX company. Polyjacking.com installs the polyurethane foam via the following procedure:

• Using radar equipment, find voids in the soil
• Drill small 5/8 inch holes into the concrete
• Use hoses to inject the TerraThane polymer
• Apply the right amount for lifting and leveling the concrete
• Complete appropriate clean-up (which is always minimal)

The complete process usually takes less than seven hours. Mudjacking, on the other hand, may require weeks or months to complete and creates a huge mess. For additional information on mudjacking vs. polyjacking, click here.

Open Range Services is Pleased with the Results

According to Steve Walker, Open Range Services was very satisfied with the final results, “They said they knew who to call if it happened again.” Things are running smoothly again at this particular Anadarko Petroleum hydraulic fracturing station, one of six located on the Wattenberg Gas Field, which is considered the ninth largest gas reserve in the entire United States.
