The micropile installation process is relatively straightforward. Initially, a deep gap with a small diameter is drilled and then the steel component might be decreased into the hole. The diameter will often be concerning three and twelve inches, but it is going to range dependant on how and where the micropile is getting used, in addition to the load demands.
Keller can Merge our micropile technology with a number of of our other ground modification techniques to fulfill distinctive or elaborate task needs cost-properly and effectively.
