Ground improvement beneath new fill: understanding the supporting profile

The performance of a constructed platform depends on the ground profile supporting it. Where new controlled fill is placed over existing fill or natural soils, both the placed material and the ground beneath it influence how the finished platform responds to load.

Interpreting qc Response Near Sand-to-Clay Interfaces

Why lower qc values near sand-to-clay interfaces do not always indicate weaker ground conditions.

High-Energy Impact Compaction: Calibration, Correlation and Ground Response

HEIC does not measure modulus or bearing capacity directly. It measures how the ground responds to impact. This article explains how calibration and correlation transform that response into meaningful, site-specific engineering insight.

Why Modulus Matters: Moving Beyond Density in Ground Improvement

Density has long guided compaction, but it does not reflect how ground performs under load. This article explores the shift to modulus-based verification using HEIC, ICM and in-situ testing.
