Project Requirements
The project consisted of forty-six 3 MW turbines mounted on concrete towers with a hub height of 100 meters. Joints between the precast elements needed to be sealed and filled with a pumpable cementitious engineering grout.
Sika Solutions
Locally produced SikaGrout®-295 ZA was used to fill horizontal and vertical joints between the concrete segments with Sikadur®-31 CF to seal and finish the geometrical appearance of the cylindrical tower. The pore sealer Sika MonoTop®-620 was used to cover small imperfections in the concrete surface.
