Injection Boring

August 21st, 2015 by

VersaGrade, Inc. utilizes a threaded, hollow bar (30 – 40 MM Diameter) that is drilled into the ground and encased by an injected cement grout body that bonds with soils. This method is also known as injection boring (IBO). The strength or carrying capacity of each micropile is determined by calculating the type of soil, the pile length and diameter, and the amount of the grout injected.
