Rigid Inclusion

Engineered Stability for Challenging Soils

Rigid inclusions are a ground improvement technique used to reinforce compressible soils beneath structures without directly connecting to the foundation. At CNT Geotechnical, we design and install rigid inclusions to enhance load-bearing capacity, control settlement, and improve overall ground performance.

ISO 9000-Certified Manufacturing

From the first pile to the millionth, every CNT Geotechnical product meets the same exacting standards—guaranteeing uniform performance and reliability on every project.

ICC-ESR Certified

CNT Geotechnical products are backed by an ICC-ESR report, the industry-standard verification that our manufacturing process consistently meets code requirements. This certification ensures that the products we deliver are identical in quality and performance to those submitted for independent testing—giving you confidence in every pile we install.

IBC-Compliant Deep Foundation Systems

All CNT Geotechnical deep foundation elements are fully compliant with the International Building Code (IBC). With CNT, you're building on a foundation that’s not just strong—it’s code-approved and legally sound.

How it works

Ground penetration

Filling with concrete

Piles are typically installed using standard tracked or wheeled excavators equipped with a torque motor attachment. This attachment continuously monitors the applied torque during installation to ensure adherence to the design specifications.

Helical Piles are driven into the designated bearing stratum by rotating the steel shafts, a process facilitated by the torque motor mounted on the excavator or rig.

As the tool is withdrawn, concrete is pumped into the bore, flowing out of the tube to provide structural support. While the concrete remains fresh, cutting is performed mechanically. Once it has hardened, manual finishing is applied as needed.

What to Look for in a Geotechnical Vendor

Engineering and Production

CNT geotechnical

In house engineering

Ensures ability to design to a higher degree of accuracy a pile that fits the project requirements. It also to schedule engineering for higher priority jobs since we have control over that are not beholden to a subcontractor.

Uses American Made and Sourced materials

Many contracts require American sourced materials, non American materials do not have as stringent quality in their steel as American suppliers. Lastly, we like to support American workers.
