Product description

Sollroc produces the most efficient drilling hammers (DTH), built for the most diverse applications: water drilling, construction, mines etc. Our technology and unique design gives to our drilling hammers high performance, in various types of formations.

Sollroc offers a wide range of high performing drilling equipment designed for percussive drilling. In fact, we offer the most productive DTH hammers in the world. DTH drilling as a method is growing in popularity in both foundation works and in well and geothermal drilling. As the global redevelopment of urban areas continues, this trend comes with a challenge - accessing and drilling in populated areas without damaging the existing structures around the work site. It is obvious that our customers in geotechnical operations have very different demands on the equipment than those working with high production drilling in, for example, quarrying. The demand for application-tailored solutions is increasing.
