Helical piles, also known as helical piers, are factory-manufactured steel foundation systems consisting of a central shaft with one or more helix-shaped bearing plates, commonly referred to as blades or flights, welded to the lead section.
Extension shafts, with or without additional helix blades, are used to extend the pile to competent load-bearing soils and to achieve design depth and capacity. Brackets are used at the tops of the piles for attachment to structures, either for new construction or retrofit applications. Helical piles are advanced (screwed) into the ground with the application of torque.
Push piles, also called push piers, are heavy-duty steel tubes that are hydraulically driven into competent, load-bearing strata. Push piles have a sleek design with choke collars, reducing skin friction. They are attached to a remedial bracket which is mounted to the footing of the structure’s foundation. When installing deep foundation systems across Montana, our team will make sure push piers are used exclusively for retrofit applications.
Micropiles are small-diameter drilled and grouted piles. These are deep foundation systems we utilize in Montana that offer a viable alternative to conventional piling techniques, especially where there is restricted access, low headroom, challenging subsurface conditions, and noise-sensitive environments.
Micropiles are a unique foundation element because of the ability to install them in very limited access conditions and through the wide range of subsurface conditions found in the Rocky Mountain region.
Underpinning is a method used to repair, strengthen, and increase the bearing capacity of existing foundation elements by transferring structure loads to competent subsurface formations at depth. Our team in Montana utilizes underpinning for cases in which there needs to be remediation of failing foundations when adding additional loads, and during the construction of adjoining or adjacent structures in urban settings that require soil excavation of neighboring properties.
