Abstract

Micropiles were invented in Italy in the early 1950’s in response to the demand for innovative techniques for underpinning historic buildings and monuments that have sustained damage with time. The micropile systems used today are evolution from the basic small diameter cast-in-place pile. A typical micropile construction involves drilling a pile shaft to the required depth, placing the steel reinforcement, initial grouting by tremie and additional grouting under pressure where applicable. Advantages of micropiles are high bearing capacity, less site limitation problems and self-sustained operation. This piling system is therefore attractive to both the client and the foundation designer.
