ODOT PROJECT SHOWCASE • PROJECT S65868
ODOT Foundation Repair With Helical Piers in Myrtle Creek, OR
A commercial foundation and concrete leveling project at a northbound weigh station where the scale shack was leaning toward the river on the east side.
COMMERCIAL FOUNDATION REPAIR IN ACTION
One Structure. Two Repair Systems. One Coordinated Plan.
For this ODOT foundation repair in Myrtle Creek, Oregon, TerraFirma worked on the scale shack at the northbound weigh station. The structure used a slab foundation and was leaning toward the river on the east side.
Because both structural support and slab leveling were involved, the repair was completed in sequence. The crew installed helical piers first and performed the lift. Polyurethane was then injected beneath the slab after the lift to address the concrete-leveling portion of the project.
The result is a useful example of how a commercial foundation repair plan can combine complementary systems when the structure and slab each require attention.

THE REPAIR STRATEGY
Address the Foundation First, Then the Slab
The scale shack was leaning toward the river on the east side. The project sequence was important: structural support and lift came first, followed by polyurethane injection beneath the slab.
01
Stabilize and Lift With Helical Piers
The foundation was exposed at the pier locations so the helical pier system could be positioned and installed. The piering phase provided support for the affected foundation area before the concrete work began.
02
Level the Slab With Polyurethane
After the lift, polyurethane was injected beneath the slab. This second phase addressed the concrete-leveling needs after the structural portion of the repair had been completed.
PROJECT PHOTO STORY

The project photos document the work from the existing scale shack and foundation access through helical pier installation, hydraulic lift work, and the polyurethane slab-leveling phase.
HOW THE WORK CAME TOGETHER
Four Phases of the ODOT Foundation Repair
01
Expose the Foundation
The crew prepared the pier locations by exposing the foundation so the support system could be positioned where needed.
02
Install the Helical Piers
The pier system was aligned, advanced into the soil, and connected to the structure at the prepared foundation locations.
03
Complete the Lift
Hydraulic equipment was used during the piering phase as the affected foundation area was lifted before moving to the slab work.
04
Inject Polyurethane
After the lift, polyurethane was injected beneath the slab to address the concrete-leveling portion of the repair.
Why Combine Helical Piers With Polyurethane Concrete Leveling?
The two systems addressed different parts of the same project. Helical piers were used for the foundation-support and lift phase. Polyurethane injection followed to address the slab after that structural work was complete. The confirmed project sequence is what makes this ODOT foundation repair a strong example of a coordinated commercial repair plan.

Foundation Repair Homeowner Questions
What are helical piers used for?
Helical piers are foundation-support elements installed into the soil and connected to a structure with a bracket. They may be used when a repair plan calls for added support beneath a settling or moving foundation.
Why was polyurethane used after the foundation lift?
For Project S65868, the confirmed sequence was to install the helical piers and complete the lift first. Polyurethane injection followed afterward to address the slab-leveling portion of the project.
Can foundation repair and concrete leveling be part of the same project?
Yes. When both the structure and the slab require attention, a repair plan can include more than one system. The order of work depends on the specific conditions and the repair design for that property.
How does polyurethane concrete leveling work?
Small access points are created in the slab and polyurethane material is injected beneath the concrete. As the material expands, it can fill voids and help lift or stabilize the slab according to the repair plan.
Does every leaning or settling structure need helical piers?
No. The correct repair depends on what is causing the movement, the foundation type, site conditions, and the structure itself. An on-site evaluation is needed before recommending a repair system.
Does TerraFirma work on commercial foundation projects?
TerraFirma provides commercial foundation and concrete repair solutions in Oregon and Washington. Projects can involve structural support, piering, concrete lifting, or a coordinated combination of systems when the site requires it.
