Foundation and reinforcement work with Wassara

High drilling performance

Wassara is proven to be a reliable method for casing advancing. The water lubricates the casing, which enables a smoother drilling operation. When casing advancing in longer holes, Wassara is often the only feasible method. Wassara offers drill bits and casing shoes developed for the water-powered drilling technique.

Drills through any formation

As Wassara is a water-powered percussion system, it’s able to drill through complex formations, from soft clays and sands to harder rock, boulders and even through old wooden piles! The Wassara system is unaffected by water in the formation, even at high back pressure.

Safer and more benign drilling

Because water is an incompressible medium, the risk of causing damage to the surrounding services or adjacent structures when drilling is minimised. Air-powered drilling always faces a much higher risk of pressurising the formation, leading to hazard for adjacent structures.

More environmental-friendly

No dust or oil mist is created by the drilling operation, which leads to a safer, cleaner environment for both site personnel and the general public. When drilling with Wassara, it is possible to place the water pump well away from the drilling area, enabling a quieter and healthier workplace.
