Glostrext Instrumentation Method: A novel technology empowering You to make decisions based on Facts

.: Services Provided & Track Records :.


Professional services provided including :

  • Planning, supervision and conducting field Instrumentation, Data-logging, Automatic Pile Test Monitoring and Reporting Works for Static Axial Compression, Axial Tension and Lateral Load Tests for foundation.
  • Innovator and provider for reliable and powerful technology called Improved Global Strain Extensometer (GLOSTREXT) Method, designed for the needs of instrumentation and data interpretation of static load testing for driven pre-stressed concrete spun piles, steel pipe piles, bored piles, soil nails and other geotechnical and structural applications.
  • Innovative instrumentation schemes for foundation and geotechnical related Research & Development projects and technology development.
  • Preparing proposals, quantity and cost estimates on field instrumentation and monitoring works for tender bidding as well as assisting clients on innovative instrumentation schemes to evaluate performance of foundation and structures (including verifying competitive alternative proposal) by field measurement.
