The Midwestern floods of 1993 affected communities along the major rivers in ways
uncaptured by much of the news media. In addition to surface water flooding, rising
and falling ground water levels caused foundations to settle, floor slabs to heave
and underground pipelines to shift. Many homes and businesses were affected.
At the Venice Technical School in Venice, Illinois, the increase in ground water
level caused basement floor slabs to heave and buckle, as well as differential settlement
of foundation walls. After consulting with various engineering firms and general
contractors, FASTEEL® was hired to implement
an underpinning system to not only support the distressed foundations, but to lift
it back to near pre-flood elevations. After analyzing soil data and with aid from
the FASTEEL® engineer and installing two test
piers, consulting engineers went to work designing the system. The design was agreed
upon and approved by the owner. FASTEEL® crews
then worked two shifts, installing 66 1¾" helical piers to depths ranging from 30
to 38 feet below the foundation. Close coordination was required between FASTEEL® and the general contractor due to time limitations
and dewatering requirements.
The building was lifted within two weeks of the opening of classes and fall classes
started on schedule.
