Soil Testing

Concrete Testing


Houses – Buildings – Foundations – Warehouses – Industrial Projects – Dams - Waterways


Soil Excavations – Soil Profiling – Atterberg Limits – Road and Foundation Indicators - DCP Testing – MOD AASHTO and Moisture 
CBR Bearing Pressure - C3 and C4 Mix Design
Areas which results indicate a lack of bearing pressure due to non-refusal, would ideally require importing of G7-G5 material and compacting to 95%-98% MOD AASHTO upon which foundations can be founded.
Soil Excavations and Soil Profiles - Atterberg Limits - Plasticity - Liquid Limit - Linear Shrinkage.
Road and Foundation Indicators - MOD AASHTO and Optimum Moisture Content (OMC).
CBR Bearing Material Classification.
Stabilized Material Layerworks - ITS and UCS (C4, C3, Mix Design), Stabilized Content.
 Geo-technical Investigations - Foundations and Road Layerworks
Road Layerworks and Earthworks Testing
Compaction Testing – Nuclear Density Testing - Sand Replacement Test - Cement Content Analysis – DCP Testing
Asphalt Core Drilling - Cement Core Drilling
All earthworks should be carried out in a manner that promotes the stable development of the site. It is recommended that earthworks be carried out along the guidelines given in SANS 1200 (current version) and according to TRH14 Guidelines for Road Construction Materials.
Rock Aggregate Analysis – Quarry Aggregate Analysis – Compaction Layerworks Testing
Density control of placed fill material should be undertaken at regular intervals during fill construction. Geotechnical Solutions can carry out compaction test inspections of foundations prior to any concrete poured.
Aggregate Grading - Aggregate Crushing Value - ACV, 10% Fact, Relative Density (RD), Apparent Relative Density (ARD), Bulk Relative Density (BRD), Loose Bulk Density (LBD), Compacted Bulk Density (CBD), Average Least Dimension (ALD).
Flakiness Index (FI) - Sand and Aggregate Moisture Correction.
Concrete and Cement Strength Testing
Concrete Cube Crushing - (150mmX150mmX150mm) - Concrete Cube Crushing - (100mmX100mmX100mm) 
Brick Strength Testing - Block Strength Testing - Paver Strength Testing
Concrete Quality Control Testing and Concrete Mix Design - Concrete Core Drilling.
Slump Test and Sampling of Fresh Concrete - Manufacture of Concrete Cubes - on-site and in-house.
Cement and Mortar Content Analysis.
Geotechnical Investigations – Soil Report Data-sets – Independent Research Analysis
 It is recommended that excavations be carried out in the dry season as far as possible and completed/backfilled with a minimum of delay. Lateral support should be used in all situations where ground water is encountered or instability is observed.
