Delivering the Support You Need, When You Need It
All of our employees have years of experience in making the best recommendations for geotechnical construction. You can rely on our in-house training on each product with every installation technique.
CNC Foundations provides custom foundational services for deep foundations. Deep foundation services transfer structural loads to competent soils or rock when shallow foundations are not feasible due to weak, compressible soils near the ground surface.
There are many reasons why our team might recommend deep foundation services over shallow foundations. It all depends on the structure you need to build, the kind of support you’ll need, the type of soil at shallow depth, and any site constraints you might have (such as property lines, building codes, or access restrictions). We can access factors like this during our preconstruction phase. We use this time to address any safety concerns and examine the limitations at the worksite.
Deep foundations are typically connected to the structure and can be built beforehand or attached as an underpinning element afterward. Deep foundations can be made from timber, steel, or concrete, and they can be constructed by driving piles into the ground or through excavation and drilling. If deep foundation solutions are not right for the requirements of your project, ask us about our ground improvement products and services.
We deliver a strategic mix of cost-effective geotechnical and structural solutions for your construction project needs.
Our team and equipment are prepared for multiple types of soil conditions with a wide range using these types of piles:
Helical piles, sometimes referred to as anchors, piles, or screw piles, are often used to stabilize new or existing foundations. Helical piles essentially look like screws—they’re composed of one galvanized iron shaft with “fins” or helical bearing plates. These piles are then turned into the ground by a machine to the desired depth.
Micropile systems are an excellent for deep foundation solution because they don’t require any pre-drilling. As a result, they’re often used to repair existing foundations to create a stronger foundation system, rather than replacing a foundation. They’re also typically used to stabilize adjacent structures that could interfere with your project’s long-term stability.
Resistance piles — also known as push, pipe, or friction piers — are hydraulically driven systems that were initially created to address building settlement problems. These piles are “pushed” into the earth using hydraulic installation until they reach competent soil. Resistance piles are meant to underpin existing foundations or support new building load being added to an existing structure, and are most valuable when soil information is limited.

Missouri | Micropiles
On this job site, micropiles were used as the foundation solution to support the North, South, and center support columns for the new bridge.

Valparaiso, IN | Helical Pulldown Micropiles
The city of Valparaiso was installing a new 12” sanitary line. A helical pulldown micropile was chosen to support the 12” line.
Education
Normal, IL | Micropiles
A Community College was constructing a new academic facility. The sub-surface soil conditions were half engineered fill and half virgin soil.

Chicago, IL | Micropiles
We were contacted about this challenge to design and install a foundation system that would support the retrofit 14-story elevator structure.
Education
Joplin, MO | Micropiles
In 2011, the entire town of Joplin, Missouri, was left devastated as an EF5 tornado destroyed their town, including their elementary school. CNC Foundations provided a Deep Foundations solution for the new school.
Power
Missouri | Hollow Bar Micropiles
The design requirements for this deep foundation were 200 kips compression, 125 kips tension, and 25 kips shear. The soil borings revealed limestone at an approximate elevation of 135 feet. Above that was a mixture of gravelly sands, sands, sandy silts, and fill extending to the surface. The job site location was near the Missouri River.
Government
Scott Air Force Base, IL | Hollow Bar Micropiles
The project consisted of upgrading the existing building at an Air Force Base. The upgraded building will be an advanced communication center that will include black box encrypted services and other best of the best communication technologies.
Residences
St. Louis, MO | Micropiles
The existing building was constructed in 1936 and replaced the previous school building that had opened in 1883. The present 3-story building was constructed using a concrete frame with concrete block and brick masonry.
Government
Bowling Green, KY | Micropiles & Rock Anchors
The city of Bowling Green, Kentucky, acquired Federal Stimulus money to construct a new, multi-million dollar Wastewater Treatment Facility to replace the outdated facility.
Commercial, Retail, Office
Indianapolis, IN | Micropiles
Downtown Indianapolis is famous for the Circle. A new building was to be constructed within the Circle, next to an existing historic building from the 1890s. Access to the site was limited through an alley off the main street into the Circle.
