- Excavation and removal of the existing concrete collar to expose the turbine foundation.
- Precision drilling to locate and access cavities at the bottom flange of the steel column..
- Injection of hydrophilic resin to fill voids and seal around the embedded can, reducing tower movement.
- Installation of a new concrete collar to improve drainage and direct water away from the tower base.
- Application of the Triflex Towersafe waterproofing system to protect the interface between steel and concrete.
- Backfilling and compaction of the surrounding area.
Freyssinet delivered remedial works to stabilise wind turbine foundations and install a long-term waterproofing solution, addressing movement, water ingress, and durability issues across multiple locations.
To ensure lasting performance and consistency across all sites, a carefully developed methodology was implemented. This included targeted excavation, structural inspection, precision coring for resin injection, and the application of a high-performance waterproofing system. All works were executed with minimal disruption to operations and in line with strict quality and safety standards.
