As the name suggests, trenchless pipeline construction requires no digging.

The most common use for this system is the laying of new house supply lines. This refers to the connections from the main line in the street to your house. Such supply lines can include water, electricity, gas, TV, telephone, fibre optics or geothermal energy.

With the Mini Twinny system, pipes can be pushed through the ground (by means of a controlled drill head), while the E-Z-Jet system drills (with water) a micro tunnel, in which a new pipe can be inserted. The Grundomat system is used to push pipes through the soil.

In horizontal directional drilling (HDD), a controlled drill head is also driven through the ground to create a micro-tunnel. However, a flushing mixture is also pumped through the rods to support the drill channel. This allows much larger dimensions. You'll find more examples below in our gallery.

Attractive advantages, which are made possible by the system, are among others the shortened construction time, the massive cost savings, the cleanliness & precision and the avoidable land damage to your property.
