Deep Foundations
Deep Foundation Solutions for Any Site
CNT Geotechnical provides advanced deep foundation systems that make large-scale construction possible—no matter the soil conditions. From helical piles to rigid inclusions, our custom-engineered solutions are built for strength, stability, and long-term performance. With proven expertise in geotechnology, we deliver reliable results even on the most complex or hard-to-reach sites.
Compliance and Approval
Executed DOT approved projects
Executed Federal Contract projects
Executed FAA construction projects
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.
Our Expertise
Helical piles
Precision-Engineered Screw Piles for Every Challenge
Helical piles offer unmatched load capacity and quick, efficient installation with minimal site disruption. Perfect for weak soil conditions and sensitive environments.
Grouted helical piles
Hybrid Solutions for Enhanced Load-Bearing Capacity
Cased / Uncased
Grouted helical piles combine the ease of helical installation with added strength through skin friction, ensuring reliable performance for heavier loads.
Driven piles
Impact-Driven Solutions for Large-Scale Projects
Concrete / Steel / Wood
Driven piles offer exceptional durability for heavy construction and marine projects, ensuring stability in demanding conditions.
Sheet piles
Earth Retention for Secure Construction
Sheet piles are steel sheets with interlocking edges, ideal for retaining soil and water in marine or earth retention projects.
Rigid inclusion
Reinforcing Weak Soils Without Structural Connections
Rigid inclusions reinforce compressible soils, reducing settlement and increasing bearing capacity without connecting to the structure itself.
Soil injection
Strengthening Weak Soils Through Ground Improvement
TERRA-LOK™
Soil injection strengthens soft soils by mixing them with cementitious materials, improving stability and preventing settlement.
Aggregate piers
Reinforcing Fine-Grained Soils with Stiff Columns
Aggregate piers improve load distribution and reduce settlement in weak soils, providing a cost-effective solution for challenging sites.
