DSI® Drill Hollow Bar System – Stability in weak Ground
Does your project need to be completed as quickly as possible? As a self-drilling ground control system, our DSI® Drill Hollow Bar is an efficient solution. Drilling, installation and optional grouting are carried out in a single operational step, thus saving a significant amount of time in comparison to conventional systems.
Our hollow bar system is very flexible: The range of applications extends from soil nails to ground anchors and micropiles up to rock bolts and rock anchors.
Are weak ground and unstable boreholes posing a problem for you? The DSI® Drill Hollow Bar System is an efficient and safe solution. In addition to the previously mentioned applications, the DSI® Drill Hollow Bar System can also be used as a forepoling element for pre-support or as a lance for grouting work, thus ensuring more safety in your project.

Pre-Support – proven Systems for Stability in Advancement
Is your tunneling project located in ground that is prone to subsidence, weak or jointed? We have the solution. Our AT – Pipe Umbrella System increases the stability in the working area by transferring loads in the longitudinal direction, thus offering more operational safety in the heading area. Furthermore, we offer you spiles and forepoling boards. With our universally usable systems, we are going to find the best technical solution for your project.Drainage Drilling Systems – Time saving Ground Dewatering
We offer two efficient and safe drainage systems. Our AT – TUBESPILE™ Vacuum Lance is ideal for the temporary drainage of the ground near excavations and can be easily installed self-drilling. Our AT – Drainage System is available to you for deep reaching drainage. You can use this system both for drainage work parallel to tunnel advances and for water saturated slopes.Passive Support – flexible Adaptation to the Excavation Geometry
Do you require a passive ground support method for immediate stabilization? Our variety of Lattice Girders, support profiles, rock bolt mats and straps can be flexibly adjusted to requirements on site. In highly converging rock mass conditions, Lining Stress Controllers (LSC™) ensure controlled stress release. All of our systems have proven themselves in use for decades.
Injection and Waterproofing Systems – the Solution for pressing Water
To seal against water and consolidating loose rock in Tunneling, we offer you the DSI® Inject Resin System. You can also use these systems extremely well for consolidating non cohesive soils and as a high quality injection product against hydraulic ground seepage. Our injection systems ensure the fast consolidation of fault zones in Tunneling at all times – for more safety in your project.
