Anchor drilling

Our water-powered drilling technology has a proven track record of its ability to drill long straight holes, which is essential when drilling for anchoring.

Cut-off walls

Cut-off walls often involves drilling in water rich formations which is easily done with the water-powered Wassara DTH hammer.

Ground reinforcement

Jet-grouting holes can either be pre-drilled using the water-powered Wassara DTH hammer, or in one single pass with the unique Wassara Jet-Grouting hammer.

Forepoling

The high water flows one might encounter during casing advancing/forepoling during tunneling will not interfere with the Wassara-hammers performance.

Survey, grout and drainage holes

Regardless of tunneling method, traditional drill and blast or Tunneling Boring Machine (TBM), there is a need to drill long straight holes.
