DYWI® 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 DYWI® 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 DYWI® Drill Hollow Bar System is an efficient and safe solution. In addition to the previously mentioned applications, the DYWI® 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.

Anchors and Rock Bolts – flexible Stabilization Underground

We offer a wide variety of anchors and rock bolts for Tunneling. The following products form part of our comprehensive range of anchors:

  • Mechanical Anchors, Resin and Rebar Rock Bolts
  • CT-Bolt Combination Rock Bolts
  • Friction Stabilizers
  • OMEGA-BOLT® Expandable Friction Bolts
  • POWER SET Self-Drilling Friction Bolts
  • GRP Anchors and Rock Bolts for high quality ground support in Tunneling

With these products, we can always provide you with the optimum solution for the individual requirements of your Tunneling 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 DYWI® 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.
