Our Services

We provide comprehensive geotechnical services to ensure the safety, stability, and longevity of your construction projects. Our team of experienced engineers and geologists works to understand the unique characteristics of your site. We provide specialized solutions in Geotechnical Engineering, Engineering Geology, Hydrogeology, Drilling, and Geological Sciences. Our team delivers reliable site investigations, soil and rock testing, groundwater assessments, and drilling services to support infrastructure, mining, and environmental projects. With a strong focus on accuracy and efficiency, we help clients make informed decisions and ensure the success of their projects.

Geotechnical engineering

Site investigations

Services start with investigations to understand the subsurface conditions of a site. This can involve field mapping, test pitting, drilling boreholes, and collecting soil and rock samples.

Laboratory testing

Collected soil, rock, concrete, and asphalt samples are tested in a laboratory to determine their physical, chemical, and mechanical properties, such as shear strength, permeability, and compaction characteristics


Foundation Engineering

based on the site's subsurface conditions and the building's specific loads, optimal foundation is designed. This includes designing both shallow foundations (like strip footings) and deep foundations (like piles).






 DRILLING ANG EXPLORATION

Geotechnical Drilling

We carry out auger, rotary core, and percussion drilling to obtain representative soil and rock samples for geotechnical investigations and foundation design.

Testing

Our borehole testing services provide accurate data on subsurface conditions to support design and construction. We conduct Standard Penetration Tests (SPT), Cone Penetration Tests (CPT), permeability tests (Lugeon, falling/rising head), packer tests, vane shear tests, and pressure meter tests. These methods help determine soil strength, density, permeability, and overall ground behavior, ensuring reliable information for geotechnical analysis and foundation design.


Exploration Drilling

We support mineral and groundwater exploration through core recovery and sampling techniques that deliver reliable geological information.

HYDRO-GEOLOGY

Hydrogeological surveys

Our experts use scientific methods to survey your property and accurately pinpoint the best drilling location and estimated water depth, maximizing your chances of a successful yield.


Water quality and yield testing

We conduct comprehensive tests to determine the volume of water your borehole can supply (yield) and ensure the water quality meets safety standards for its intended use.


Turnkey solutions

We manage every step of the process, from planning and surveying to drilling and final installation.
