The PERI VARIO GT 24 wall formwork and ST 100 shoring system already met the current requirements of the project. These systems were safe for using, worked well under every environment and weather conditions. The simple assembly as well as dismantling of the systems not only reduced the labor requirement and increased the productivity at site. But it also helped the delivery to the remote locations. Besides that, the continued technical support from PERI team was very helpful during the concreting time. PERI has provided us the professional services and the high-quality products.
