Release – Improved Jet Grouting hammer!

During the Geo Fluid exhibition in Italy LKAB Wassara released the improved Jet Grouting hammer, W100JG - the hammer for effective single pass Jet-Grouting operation.

During the Geo Fluid exhibition in Italy LKAB Wassara released the improved Jet Grouting hammer, W100JG - the hammer for effective single pass Jet-Grouting operation.

This hammer combines the characteristic effective water-powered drilling of the W100 hammer with an integrated jet-grouting monitor. Compared to the previous version the new hammer has an integrated check valve that prevents particles from coming into the hammer through the bit when drilling is stopped and foremost during the jet-grouting sequence.

Furthermore with the importance of a fast service procedure in mind, Wassara constructors have redesigned threads and made the grip-area on the backhead larger to improve serviceability.

All the changes to the hammer have been tested together with two major contractors and were proved successful.

Where boulders and other obstacles have made jet grouting complicated, the Wassara Jet Grouting Hammer delivers grout piles in two easy steps.

You can find technical information in our new Data sheet and Start-up guide for W100JG

Furthermore you can read the interesting Case Study – Bergendahl foods, where our W100JG hammer was used.
