Our Services
Deltek is a trenchless contractor with more than 20 years of field experience, providing horizontal directional drilling, pipe jacking and auger boring and trenchless pipe bursting across Türkiye from its Istanbul and Izmir offices. With a fleet of up to 250 tonnes in HDD and 800 tonnes in pipe jacking, we install pipe and cable lines of every diameter from 2 mm to 2000 mm under rivers, motorways, railways and city streets without open-cut excavation. We carry out a free feasibility and site survey for each of the four services below.
Horizontal Directional Drilling
HDDThanks to a mechanism that can be steered in three dimensions underground, we now install your infrastructure more easily and with less effort. We take cable and pipe lines underground without damaging existing lines and without disrupting surface activity or traffic. Less excavation, more technology. Give us the entry and exit points and leave the rest to us!

Auger BoringWe install your steel pipes of up to 2000 mm diameter underground without endangering human life, in a short time and at fair cost. Adjustable shaft dimensions and high machine capacity let us deliver precise, effective solutions even over long distances without intermediate stations.

Pipe BurstingEver-growing infrastructure demand is one of the hardest problems to solve in city centres, where daily activity often does not allow roads and areas to be closed for long. With our pipe bursting and renewal systems we install new pipes in place of the old line without excavation — and, if you wish, in larger diameters!
