HORIZONTAL DIRECTIONAL DRILLING

Horizontal Directional Drilling or HDD is a controllable trenchless method of laying underground pipelines like water, sewer, drainage, oil, gas, cables under road, bridges, landscape, river, metro etc. based on using special drilling machines. This installation technique has proved to be extremely friendly towards the environment, with only minor ecological interventions. HDD technology is particularly appealing construction options in urbanized area with numerous existing underground utilities, heavy traffic..
