Product Description
Product Description

Swellex expandable rock-bolting system has gained wide recognition in the mining and tunneling industry. This unique rock bolt consists of a welded tube folded in upon itself, sealed at one end. It is re-expanded using a high pressure water flow provided by a special pump and adapter. The bolt is expanded inside the borehole drilled into the excavation wall. The installation process is easy and very similar to other rock bolt installation processes, making Swellex rock bolts accessible to all operators.
Applications: Swellex rock bolts are extremely versatile and can be used in a variety of excavation, from tunneling to mining. A very typical application in tunneling is to use Swellex as pattern bolts to support, reinforce or consolidate the periphery of an excavation. The density of bolting depends of the size of the excavation and the self-supporting qualities of the rock mass. In mining, common applications like roof and hanging wall bolting have adopted. Swellex as a rapid and performing stabilisation device. Because Swellex is expanded inside a borehole smaller than the folded tube circumference, it is not sensitive to hole diameter, rock quality or water conditions and provides a good anchorage capacity in most tunneling and mining conditions.
