Our Approach toward work

1. Geotechnical Investigation

Our Geotechnical Investigation team provides a comprehensive range of services for engineering and infrastructure projects like Bridges, High embankments, Buildings, Factories, towers, Foundations for other load-bearing structures in different terrain conditions like Major Rivers, hilly terrain, large waterways. Activities involved are i. Geotechnical studies for designing super/substructures through borehole exploration, in-situ testing,

geophysical exploration etc.

ii. Identification of problematic soils and remedial measures

iii. Slope stability analysis, recommendation for ground improvement techniques

iv. Testing of soil/rock samples in the laboratory to determine its physical and engineering properties

v. Analysing all field and laboratory data to evaluate safe bearing capacity and safe bearing pressure of the soil/rock for given foundation sizes and necessary recommendations for open/pile foundation design/construction.

vi. Testing and analysis of sub grade and sub base materials for roads and runways, suitability tests of material for embankments, clay liners for engineered landfills, fill material for reinforced earth retaining walls etc.

vii. We have Hydraulic & Rotary drilling rigs (drilling capacity up to 100mt), manual Augurs (drilling capacity up to 12mt)
