Geo-Technical Investigation & Laboratory Testing
Geo-technical unit was created in the Company since its inception in 1992. The Company onwards gradually developed the resources to carry out land based geotechnical investigations in all types of soils and rocks. In the year 2005, the Company further enhanced its expertise by conducting drilling under flowing water conditions. This achievement was earned because of our own in-house research and development. Today we offer a comprehensive and versatile range of soil investigation techniques from simple test pits to more sophisticated drilling and in-situ testing methods.
We are experienced acting as prime geotechnical contractor. Our site managers, supervisors are thorough professionals well versed with soil and rock logging according to British and other relevant international standards. We own and operate extensive fleet of drilling and allied field testing equipment. Our drilling manpower belongs to our permanent staff. Their exclusive use of our drilling equipment allows us to design the project not only based on actual testing parameters, but based on Engineering judgement also.
The Company, by virtue of its vast experience in handling Overhead Power Transmission Line and Pipe Line projects, has gained expertise to manage projects in which extensive logistic is involved. Geo-Technical Investigation of Iran-Pakistan Gas Pipe Line (800 km long) was one project in which logistics was of paramount importance in execution, the terrain of this project comprised desert, hills, marshy land and plain areas from Iran Pakistan border near Jiwani along the Makran coast to the city of Nawabshah. This project was completed by deploying nine drilling rigs simultaneously for about four months.
The Company possesses expertise to carry the following field samplings & tests:
Standard Penetration Tests (SPT)
Water Pressure Tests with Packer
Elastometer Tests for Rock
Field Density Tests
Plate Load Tests
Cone Penetration Tests
Ground Resistivity Surveys
Soil Testing Laboratory
Our soil testing laboratory is an integral part of geotechnical investigative services. It was established at the same time, when the geotechnical division was established in the Company. By offering in house soil testing we are able to provide fast and reliable results and analysis to our customers without the need of a third party.
Initially the capacity of our laboratory was limited to cater the needs and requirements of our own geotechnical division; however, later on we enhanced the capacity of our laboratory, to provide soil testing services to the third parties also.
The dedication, professionalism and skills of our laboratory team earned recognition of the Geotechnical division of NESPAK, when they included the name of our laboratory, in 2007, in their approved panel of soil testing laboratories.
Our laboratory is fully equipped to perform soil testing meeting relevant ASTM and British Standards, detail of tests that we perform are as follows;
Grain Size Analysis by Sieve Analysis and Hydrometer
Unconfined Compression Tests
Direct Shear Tests
CBR (California Bearing Ratio)
Standard/Modified Proctor Tests
Chemical Tests, including Sulfates, Chlorides, pH Value and Total Dissolved Solids
