OUR HISTORY
The Expander Body (EB) concept was developed by the Swedish engineer Bo Skogberg during the 1980’s and later developed Bolivia during the last decade. It basically consists of a folded steel tube with a cylindrical cross section. By injection of grout the EB can be expanded, thereby creating a water-tight steel balloon of high strength. Gradually, new applications of the EB system were developed, such as for soil anchors, driven, vibrated and bored piles, and micropiles
