Reliable Proctor Compaction Test Apparatus for Accurate Soil Density
Get precise, field-proven compaction results with our lab and field Proctor testing systems— trusted across North America.
Ensure Soil Stability with Trusted Proctor Compaction Testing Systems
The Proctor Compaction Test Apparatus is a cornerstone in geotechnical engineering, used to determine the optimal moisture content at which a given soil type achieves its maximum dry density. This test is crucial for infrastructure planning, roadwork, foundation stability, and other load-bearing applications. Accurately evaluating compaction characteristics ensures that projects meet safety, strength, and durability standards before full-scale implementation.
Soil Ground Testing offers a full line of Proctor Compaction Test solutions tailored to both Standard and Modified Proctor test methods. As a North America-based B2B company, we support civil engineering firms, construction contractors, educational institutions, and environmental agencies with reliable, lab-grade systems. With a strong presence across the U.S. and Canada, our expertise, commitment to customer support, and cutting-edge technologies allow us to deliver field-ready, scalable solutions that enhance operational efficiency and reduce project risk.

Case Studies
Municipal Road Project, Texas
A county road commission in Texas integrated Soil Ground Testing’s Proctor apparatus to evaluate expansive clay layers before resurfacing over 18 miles of rural road. The modified Proctor test helped identify critical moisture content levels, significantly reducing cracking and pothole formation post-construction.
Bridge Foundation, Illinois
A bridge engineering firm in Illinois used our digital-enabled compaction test systems to optimize soil density near a waterway prone to erosion. With real-time cloud-based data capture, the team could adapt quickly to field conditions, meeting all safety standards and avoiding costly delays.
Pipeline Installation, Alberta
During a large-scale pipeline installation, a Calgary-based geotechnical company relied on Soil Ground Testing’s Proctor compaction system to ensure stable bedding material along permafrost zones. Our compact, field-ready kits ensured rapid testing and compliance with CSA A23.1 standards in subzero conditions.
