Soils & Aggregate Testing
Classification, compaction, strength, and durability testing for earthworks, roadbase, and structural fill - delivered against the full SANS 3001 suite.
Soils and aggregates, tested to specification
Every earthwork, roadbase, and structural fill project depends on accurate material characterisation. We test classification properties, compaction behaviour, strength, and durability - from Atterberg limits and Mod AASHTO to CBR and stabilised material strength.
Our results are used across SANRAL corridors, municipal road rehabilitation, bulk earthworks, and quarry quality control. Data is reported to SANS method specification and can be submitted for tender documentation, construction sign-off, or dispute resolution.
