NABWA contracting company specialized in the works of horizontal drilling to extend the facilities (water-electricity — wastage telecommunication).

The importance of expanding the pipes with close drilling methods (without opining the ground) is increasing day after day for important environmental and economic reasons. The tunneling technique with these methods is extending to all the geological and hydrological conditions all over the world. As well as the research and development process will continue in order to meet the increased requirements of customers and contractors in the international projects for pipes expansion; whereas it is necessary to develop and improve the equipment permanently in order to make the tunneling technique of close drilling more economic and more powerful to compete. And it is often using the closed drilling methods in the crossroads and high ways and railway intersections and rivers intersections and some buildings like homes and laboratories and the deep sites and underwater places. Mostly, there is no need to open largely the ground surface but the development of the accepted executive standards and the procedures lead to more quality control and insurance.
