This technology is analogue to the mini trench  but both the drillings and equipment employed are of extremely reduced dimensions. In particular, the surface drilling has a maximum length of 1.6cm with a maxi  depth of 15 cm-

This technology is particularly indicated, both in urban and extra urban environments, for the laying of subservices under pavements, roads, verges, parking areas or university campus where plant compressive stress is limited when superficially laid.
