The Grimsel dam project in Switzerland is one of the most challenging and important infrastructure projects in the Alpine republic. At an altitude of over 1,900 meters, extreme climatic conditions become an everyday companion during construction. KTI is proud to have made a significant contribution to the successful implementation of this project with its innovative SAUTER concrete heating technology.

At the start of construction in 2019, KTI delivered a SAUTER HWS300 and a SAUTER OLH300 to the Bernese Oberland. The construction of the new dam wall required the highest concrete temperature standards. Due to the extreme ambient temperatures, construction could only take place between May and October, so the correct temperature and durability of the concrete had to be guaranteed. Our specialized systems ensured precise temperature control and uniform heating of the concrete, allowing for optimal processing even in extreme sub-zero temperatures. Thanks to the modular design and quick installation, KTI was able to flexibly adapt the SAUTER heating solutions to the conditions on site. The high-performance heating systems from KTI SAUTER ensured that the project was completed on time while meeting the high quality requirements. The Grimsel Dam project impressively demonstrates how KTI and the SAUTER product group successfully master the challenges of complex construction projects under extreme conditions thanks to innovative technologies and many years of experience.
