Over the years Barton Southern has merged its own grouting technology with that of European experts. The result has provided a unique approach to soil grouting and structure encasement practices. In this extremely specialized field, Barton Southern has filled voids and installed numerous sub-grade grout barriers in earthen dams, underground vaults and transit systems. A major advantage of the chemical grouting technique is the ability to strengthen existing soils without the need for excavation or disruption of facility operations.

As the popularity of trenchless technology continues to grow, engineers and contractors are finding that they can use chemical grout to solve a multitude of problems caused by poor soil or excessive water conditions utilizing a method called "probe grouting." During a typical probe grouting repair, a small diameter pipe is driven down from the surface to the vicinity of the instability. Then a hydrophobic, water-reactive polyurethane grout is injected through the pipe. If the conditions require it, water may also be injected with the grout material using a two-component "F-Valve" injection nozzle. At certain intervals, the pipe is raised several inches to allow the grout to permeate the soil. Once a grout "column" has been successfully created within the soil, the pipe is withdrawn. Multiple probe grouting injections may be made, depending on the nature of the repair.

Probe grouting is a quick, cost effective way to fill voids and stabilize soils. Repairs can be done by a small crew using portable equipment and the necessary amount of polyurethane grout material -
all without costly excavations and irritating disruptions to your facility operations. Barton Southern’s repair methods allow you to continue
