MICROPILES

Drilled Micropiles (DMPs) range from 4” to 12” in diameter. They are used where other deep foundation elements are not feasible due to access, headroom, inability to support heavy equipment, or for loads that do not require the capacity of a drilled shaft. DMPs are the most versatile of the deep foundation elements. Projects can be performed in existing structures, basements, and alleys. They can be used for high and low capacities, large or small overall foundations, unrestricted or the most highly confined sites. The management of spoils with berms, remote settling tanks and diverters is coordinated with the site contractor and owner for efficiency and the ability to minimize the mess typically expected with microdrilling jobs has become a part of the system used especially when working in occupied indoor spaces. Hub performs pile load tests meeting both job specific and local requirements. Our fleet of four colloidal grout mixers and trained personnel yield typical grout strengths of 6500-7500 psi. Many employees have attended a 40 hour grout school at the Colorado School of Mines. Hub has innovated new designs, installation methods, and logistics practices to meet demanding schedules and overcome the challenges of the modern jobsite.
