GEOTECHNICAL ENGINEERING & DRILLING

THE COMPANY - BUSINESS SCOPE

The four technical divisions of the company provide five fields such as Site Investigation, In-Situ Testing for Construction Industries, Laboratory Testings, Field Instrumentation Works and Specialist Geotechnical Works.

  • Our Field Investigation teams consist of experienced personnel who have undertaken jobs in various site conditions such as failed slope, steep hills, rugged jungles, pond, swamp and offshore. Main projects include :-

           Quarrying
           Road Constructions
           Housing Developments
           Industrial Developments
           Multi-Storey (High Rise) Developments
           Resorts & Recreational Developments
           Water Supply, Sewerage, Drainage & Irrigation Projects
           Off-Shore Development such as Jetty, Island Resorts
           Others Geotechnical & Geological Projects

    Our field investigation sections can operate eight (8) units of Rotary wash boring machines at any one time. These machines equipped with complete set of equipments which are capable in carrying out the following tasks :-

           Soil / Rock boring to depth of 100 m below ground level
           In-Situ soil samplings such as disturbed samples, undisturbed Samples, mazier coring, rock coring and etc.
           In-Situ Testing such as SPT, Field Vane, Permeability Test, Pumping Test and etc.
           Other methods of site investigation works of Mackintosh Probe, Hand Auger and Trial Pits.

  • Our field technicians are capable in carrying out testing required by the construction industries such as :-

           Pile / Plate Loading Tests
           In-Situ Field Density and California Bearing Ration (C.B.R) Tests
           Non-Destruction Concrete Testing

  • Our well equipped laboratories together with the experience laboratory technicians are capable in carrying out testings such as :-

           Permeability Test
           One-dimensional Consolidation Test.
           Rock Strength Test such as Unconfine Compression (UC) and Point Load Test.
           Construction material testings such as Compaction, C.B.R and full range of Rock Aggregates Tests and etc.
           Physical Property Tests for soil; Nature Moisture Content, Sieving and Hydrometer (particle size distribution),            Specific Gravity, Atterberg Limits and etc.
           Soil Strength Test such as Unconfined Compression (UC), Unconsolidated Undrained (UU), Consolidation            Undrained (CIU), Shear Box Test, Torvane, Pocket Penetrometer, Motor Vane and etc.
           Tensile Test

  • Our field instrumentation teams consist of experience personnel, who are capable to install and carry out periodical monitoring for settlement plates, Piezometers, Inclinometers and etc. at construction fills area and for slope rehabilitation projects.

  • Our specialist teams are capable and have successfully carried out specialized Geotechnical jobs in the following fields :-

           Micropiling
