Hollow bar applications remove the need for non permanent casing in collapsible soils and likewise provide Micropile installation equipment elevated grout permeation and efficient micropile diameter, raising capacity.
Micropiles is usually used for new construction applications as well as for remedial repair of constructions. Micropiles are uniquely like minded for areas with limited entry and low headroom the place large load capacity is required and standard drilled shaft or pushed pile installation is just not possible.
