Geotechnical Construction & Foundation Treatment

SERVICE OVERVIEW

GEOTECHNICAL CONSTRUCTION – FOUNDATION TREATMENT

PSC provides geotechnical construction, foundation treatment and defect repair solutions for energy, industrial, infrastructure and civil works. Solutions are selected based on geological conditions, test results, the condition of the structure and technical requirements, in order to increase bearing capacity, control deformation, prevent seepage and ensure that structures operate stably and safely.

VALUE DELIVERED TO PROJECTS

With integrated capabilities in site investigation, testing, inspection and construction, PSC supports a coordinated process – from identifying causes and developing technical solutions to carrying out the work and assessing the results. This approach helps improve foundation stability, restore the functionality of affected structures, ensure safety and extend service life.

PSC IS COMMITTED TO LONG-TERM PARTNERSHIPS WITH INFRASTRUCTURE PROJECTS, BUILT ON RESPONSIBILITY AND DISCIPLINE
