Proven Expertise in Industrial & Energy Infrastructure Projects

01. 150+ Nuclear Reactors

More than 150 nuclear reactors have been protected from overpressure and radioactive leakage using Freyssinet technologies, allowing them to operate safely beyond their original design life.

02. 120+ LNG Storage Tanks

We have improved the safety and energy efficiency of over 120 LNG storage tanks, including those located in deserts, arctic regions, and seismic zones.

03. 12+ Gravity-Based Concrete Structures

Our corrosion protection systems have been applied to more than 12 gravity-based concrete structures exposed to harsh climates and marine environments.

04. 30,200 US tons moved

In South Korea, our specialist subsidiary Hebetec shifted a gas production platform weighing approximately 32,000 US tons over a distance of 656 feet, demonstrating our expertise in precision heavy lifting.

Meeting the Highest Standards in Technical Precision

While our systems often represent a small portion of overall project costs, they play a critical role in construction timelines and safety performance. Their placement on the critical path means they must meet the most demanding requirements in terms of quality, reliability, and responsiveness.

Our pre-stressing systems serve as the final barrier against radioactive leakage. Their manufacturing and installation are governed by strict nuclear safety protocols and CFSI (Critical for Safety Item) management standards.

We work closely with project teams from the design phase through final execution to optimize installation schedules. Our teams are trained to respond quickly to unexpected challenges and propose effective solutions without delay.

Our engineers provide practical solutions to structural challenges that arise during the construction of concrete structures, even when those issues fall outside the original scope of intervention.

We conduct full-scale testing before the design and construction phases to validate post-tensioning methods and equipment. These tests ensure that our systems meet the highest standards for performance and safety.
