Main information

The SmallRotoSonic excels through capturing the powerful sonic force in an extraordinarily small and manoeuvrable package, combining efficiency and cost-effectiveness. This rig makes the difference and accelerates your drilling and sampling productivity for a broad variety of applications!

Why use direct push when 150 Hz RotoSonic delivers faster and better results and provides extremely undisturbed samples. See specifications sheet for detailed information. 

''Our customers benefit from the small foot print of the SmallRotoSonic while maintaining productivity and sample quality''

Robert Kreilick, President & CEO at Summit Drilling   

Sonic drilling simply is the smartest and most efficient way to penetrate soil layers, be it dry or saturated, clay or gravel. Due to the combination of the enormous up-and-down and rotation speed of the drill string, there is very low adherence of soil particles, and very low smearing over different layers. There are no above ground cuttings so the drilling place stays clean. Due to the inertia effect of stagnant soil versus rapidly moving casing, samples do not compact. With our AquaLock sampler you can obtain samples up to four meters. Tools never get stuck too because you can also pull sonic assisted. Rig weight stays low because lowering is done in a fluidized soil paste. Peak forces on casing and mast are low compared to hammering or auguring. The drill head features a rotation function for rapid twisting and untwisting of casing rods.
