Thatcher Foundations, Inc. has been the clear leader in
pile driving in Chicago
for decades. We have driven piles for everything from private residences and
local businesses to some of Chicago's largest buildings. From over 52,000
timber piles driven for the Jardine Water Purification Plant in 1964 to over
2,200 H-piles for the new Soldier Field in 2002, Thatcher Foundations has been
the contractor to get the tough, big jobs done right and on schedule.
specialize in driven piles because we believe they offer many advantages:
A driven pile is a tested pile. As we drive the pile a driving log is kept.
The driving log verifies the actual soil conditions encountered by each pile,
rather than the assumed soil conditions based on borings scattered around the
site. This enables us to further optimize the foundation and eliminate the
We pride ourselves on our extensive load test procedures. We provide load
testing and probe piles to establish the length of piles that will be required
and minimize cost. On some sites, the length may vary + or - 20 feet.
one or more of the following methods for each installation:
- Static load testing. We have conducted load
tests up to
740 tons ultimate capacity (370 ton design capacity)
- Wave Equation Analysis (WEAP)
- Pile Driving Analyzer (PDA)
We use natural materials (timber piles) or manufactured
structural shapes. All piles conform to ASTM standards.

years of experience, our engineering expertise, and the latest software, we
can predict the equipment that will be required, eliminating schedule delays.
We're ready to work the day we arrive.
We drive piles to a pre-determined blow count (x number of blows per
foot or inch). If the length of pile is unable to achieve the blow count due
to unexpected subsurface conditions, the piles may be spliced. The splice is
designed to exceed the strength of the pile, therefore there is no loss in
Driven piles can easily accommodate lateral loads through the use
of battered piles. Piles may be easily battered in any direction to best
transfer the load.
You only buy what you need.
Costly extras due to unexpected subsurface conditions are minimized.
Driven piles require no set-up or cure time. You can build on the pile as soon
as it is driven.
H-piles are the most widely used. The most common profiles and their
allowable structural capacities are shown below. Geotechnical capacity often
may be less.
Driven piles reduce or eliminate the amount of soil that must be removed.
Particularly advantageous if the soil is contaminated or hazardous, lessening
the owner's risk.
Types of Driven Piles
Thatcher Foundations utilizes many different
pile types depending on the soil
conditions, foundation requirements, and site location.
Some of the types of
piles used are:
- Steel H-piles
- Steel pipe piles
- Timber piles
- Pre-stressed concrete piles (various profiles)
* Under special conditions
We use several different types of hammers to install H-piles. The hammer
selection is dependent on the soil conditions, required capacity, site
location, and pile types among other factors.
Some of the hammers that we use are:
- Air (single-acting and differential)
- Hydraulic Impact
- Hydraulic Vibratory
