Helical
piles are used today in the construction of new homes and the stabilizing
of existing homes in areas and regions with poor soil or flooding issues. It is
a manufactured steel system that is a part of your home’s foundation consisting
of a central shaft that has helix-shaped plates bored into the earth below the
foundation; and, attached with brackets to the structure in order to stabilize the
foundation
of a structure. These piles are literally screwed into the earth using high
applications of torque. This foundation pile will guarantee that any structure
it supports has a solid anchored base. The methodology should not be unfamiliar
with anyone considering that it has been used historically for clotheslines and
above ground housing. Once the piles are inserted they can hold weights of
50,000 pounds each!
Helical piles are designed so that the axial capacity is
generated and bore by the plates which have been advanced against the soil.
These plates are spaced in such a way as to prevent the load from being born by
a single plate. Each plate contributes to the overall stress thus creating a
stable pile. This means that each helix plate is both independent and working
in a conjunctive group to bear the weight of the structure against the pile
shaft. The helix geometry discourages soil
disturbance and creates a “clean” environment and surface area surrounding
the installation.
The advantages to this type of system are numerous. It is a
high capacity alternative for deep foundations required by law and/or
environment that can be installed in tight areas of limited access. Because of the system used to install them
this can happen far more quickly than other types of pile systems and concrete
foundations can be poured same day. They can also be retrofitted easily to
existing structures (see a structural engineer for details).
