In saturated and populated urban contexts, we need to use alternative technologies instead of the traditional ones. Trencher technology is an extremely valid solution. Compact and easy to handle, the Trenchers guarantee a rapid installation of underground services without risk to the operators and the population; because they allow to cut the diameter of the bitumen necessary to lay the cable to the depth Desired. The resulting material is transported and is so small that it can be reused directly for the restoration of the road surface. In this way, cumbersome and risky yards are avoided and operating costs are reduced.
