FAQ About Soil Testing
Per SBC 303, a geotechnical investigation must include: exploratory borings, Standard Penetration Test SPT (ASTM D1586), grain size analysis (ASTM D422), and Atterberg limits (ASTM D4318). High-rise buildings and critical facilities require additional tests such as CBR and Plate Load.

Soil Testing in Riyadh — Collapsible Soil and Gypsum Layers
Riyadh's soil presents two major geotechnical hazards: collapsible soil that appears firm when dry but collapses suddenly upon wetting (causing differential settlement), and gypsum layers hidden beneath hard caliche crusts that dissolve over time to form voids and sinkholes. TECHNO Soil Lab measures collapse index per ASTM D5333 with specialized oedometer testing, quantifies gypsum content layer by layer, and performs SPT with disturbed and undisturbed sampling. Our reports deliver foundation recommendations addressing both collapse and gypsum dissolution risks — essential for Vision 2030 megaprojects like King Salman Park and Diriyah Gate.
