We are leading in Compaction Testing
Compaction Testing
Compaction testing is the process of packing soil particles more closely together, typically using mechanical means, to increase the soil’s dry density. This improves the material’s strength and stability for construction purposes.
A series of compaction tests determine the relationship between dry density and moisture content, helping to reduce voids and improve performance. Laboratory and field tests, conducted by Normec i2 Analytical’s Site Services teams, control the compaction process, guide contractor methodologies, and ensure compliance through pass/fail criteria, ensuring effective earthworks throughout the project.
Why choose Normec?
Normec offers comprehensive testing for earthworks and construction materials, ensuring quality, compliance, and performance.
We provide all standard methods, along with specialized tests such as Moisture Condition Value (MCV), lab CBR testing, and plate load testing, including swelling characteristic measurements.
Our advanced testing capabilities deliver accurate, reliable data to help clients optimise material use, reduce risk, and maintain project efficiency—making us a trusted partner in construction and geotechnical assessments.
