A Swedish company TGB had major difficulties in sheet piling through rocky boulders. With Robit’s pilot technology, the impossible was made possible.
The rocky terrain proved to be so challenging, that the company decided to pre-drill the holes with Robit® Multi-Use casing system and retrieve the casing (406.4/12.5; L=6000 mm) afterwards. In the same project some piles were permanent and with the Robit® DTH-RoX 3-1, the same pilot was used to complete the drilling with Eco-rings.
TGB was able to complete the project on time with controlled investment. Christer Wretman, our distributor in Sweden, says: “Impossible project was turned to success with Robit Casing System”.
