Advanced Laboratory — STS Geotechnics

From Sample
to Certainty.

STS's NATA-accredited laboratory in Wetherill Park delivers soil, rock, and materials testing to Australian Standards — the data that calibrates every field observation and underwrites every STS Geotechnics and STS Environmental report.

What We Do

Laboratory Testing,
Built on Standards

Soil and rock samples recovered by GeoSense in the field are tested in our NATA-accredited laboratory in Wetherill Park — classification, shear strength, compressibility, reactivity, and contaminant screening, run to AS and ISO standards. We use laboratory data to calibrate field observations, not to replace them.

Our laboratory operates as part of one integrated process: GeoSense recovers the samples, our technicians test them, and STS's Chartered Professional Engineers use the results to underwrite every recommendation. Nothing is subcontracted out, and no result is disconnected from the engineer who signs off on it.

Soil Classification & Atterberg Limits

Liquid limit, plastic limit, and particle size distribution testing to classify soils to AS 1726.

Shear Strength Testing

Direct shear and triaxial testing to determine the strength parameters used in foundation and slope design.

Compressibility & Consolidation

Oedometer testing to predict settlement behaviour of soils under sustained load.

CBR & Swell Testing

California Bearing Ratio and swell testing for pavement subgrade design and reactive soil assessment.

Reactivity & AS 2870 Classification

Shrink-swell index testing to classify sites for residential slab and footing design.

Rock Strength Testing

Point load and unconfined compressive strength testing on recovered rock core.
