Soil Injection

Stabilizing Ground for Long-Lasting Performance

Soil injection is an advanced ground improvement method designed to strengthen weak, saturated, or unstable soils. By injecting specialized grouts or binders into the ground, we significantly enhance bearing capacity, reduce settlement risk, and improve overall soil stability. Whether working in soft clay, peat, high-moisture, or even contaminated soils, CNT Geotechnical provides custom soil injection solutions that deliver reliable performance, long-term durability, and minimal site disruption—ensuring your structure remains secure from the ground up.

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 binder

Soil injection begins with ground penetration using standard excavation equipment or injection probes to reach the target soil layer.

Once access is established, a specialized binder or grout mixture is injected under controlled pressure into the ground. This process fills voids, displaces moisture, and binds loose soil particles, transforming weak, high-moisture soils into a dense, stable, and load-bearing mass. Throughout the injection, pressure and volume are carefully monitored to ensure uniform treatment and that the improved soil meets the project’s structural and performance requirements.

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.

CNT geotechnical

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.
