Watertowers2
Over the years, the company’s technology has been used to build hundreds of water towers around the world. During the early 1960s, our method for the construction of mushroom-shaped water towers was developed. In step one, the shaft is slipformed, then the water reservoir is cast on the ground. In a final step, the reservoir...

Heavy Duty Slipform
Our Heavy Duty Slipform System is developed to be extra rigid and at the same time very time efficient for repeated dismantling and re-assembly works. This system allows for large cast-in items, as the distance between yokes are up to 3,5m, instead of more common 1,5-2m distance. The heavy duty yokes, with clearance of 1100mm...

IP CCV unit for skidding
Our skidding method as it is designed today was developed in 2004. Lifting and horizontal movement were put together in one unit (the IP-CCV-unit). The IP-CCV-unit operates over steel tracks via low-friction plastics and epoxy-treated sliding surfaces. The greatest strenghts of the method are simplicity and durability. We have now experienced over 1000 successful skidding...
