We install duct systems, using the closed method, which is also called moling – this means less excavation and thus also a smaller excavation footprint.![IMGP1149__](https://telco.ee/wp-content/uploads/2016/06/IMGP1149__-300x225.jpg)
We use Vermeer soil penetrators with a diameter between 63 mm and 130 mm; with these devices, we can install 50 mm and 100/110 mm ducts.
