Holland Drilling

Expertises

Holland Drilling is the specialist in designing and constructing trenchless crossings for underground infrastructure.

Directional Drilling (HDD)

HDD (Horizontal Directional Drilling) drilling technology allows for the simple, trenchless crossing of objects over longer distances. A small excavation at the beginning and end of the borehole is sufficient to facilitate the crossing.

Pilot-guided Auger Drilling

For decades, traditional auger drilling techniques have been used to install pipes under roads and railways using hydraulic rams and auger drills. In recent years, these drillings can also be controlled, with a pilot bore first.

Pipe bursting

Pipe bursting is a trenchless method for replacing a pipe without lengthy excavation work. With Holland Drilling’s compact machine, pipes up to 323 mm can be replaced safely and efficiently, requiring only a small excavation area.

Rocket and press drilling

Steel forging is a trenchless technique in which a steel tube is pressed under an object using compressed air, often as a casing for cables or pipes. Holland Drilling can perform this efficiently with a fully equipped rocket drilling rig for diameters up to 1,400 mm.

Dämmer specialism

Dämmer is used to fill underground cavities and prevent subsidence. Holland Drilling supplies and processes this environmentally friendly and shrink-free material efficiently on-site, with a capacity of up to 12 m³ per day.

Trenchless Removal

Holland Drilling has extensive experience in trenchless removal of old and dilapidated pipes, a growing need due to the increasing pressure on the subsurface. Using proprietary tools, various projects have been successfully completed, ranging from AC drinking water pipes to HDPE and steel pipes under railway lines.

Engineering

A sound design forms the foundation for successful drilling or jacking. Holland Drilling, through close coordination between engineers, project managers, and drilling foremen, ensures a feasible plan that is implemented safely, customer-focused, and adapted to the surrounding environment.
