less damage to the landscape or hardscape, and therefore reduced repair costs.no need to dewater the trenches (trenchless technology goes under the water table).fewer workers required, and therefore less cost.Ottawa direct drilling and trenchless pipe installation and repairs offer a range of benefits to our clients over traditional trenching, including: We don't follow a "one for all" approach. We believe that problems present for a variety of reasons, and we spend time understanding the cause and implementing a unique solution that will not only fix the problem, but prevent it from happening again in future. With an extensive clientele that has been with us for many years and referred other clients to us, our reputation is built on our ability to conceptualize innovative solutions. Over this time, we have designed and constructed hundreds of thousands of kilometers of pipeline in various diameters and cleaned thousands of kilometers worth of sewer lines using our hydrojetting services. Our high success rate is supported by our fleet of state-of-the-art HDD rigs and our highly qualified and experienced team, which includes engineers, operators and support staff. In fact, we have become the leader in Ottawa trenchless services and Horizontal Directional Drilling (HDD). We're proud to have served municipalities and public works departments in the installation of water pipes, gas supply lines, cable, internet and telecommunications conduit, and electrical supply across the state of Ontario, in cities that include Guelph, Mississauga, Woodstock, Toronto and Cambridge to name a few. We've been involved in underground construction for more than 25 years and are proud microtunneling specialists. The soil investigations have to define the accurate stratigraphy along the designed HDD profile and the other preliminary investigations, especially in the urban areas, have to show the presence of other underground services.It's our aim to make your drilling experience as seamless and uncomplicated as possible. The soils made of loose gravel and cobbles can be a problem to drill, therefore some preliminary investigations of the terrain to be crossed is necessary. The HDDs are very suitable to overcome obstacles, like rivers, canals, main roads, public areas, archaeological areas and so on and can be used for the consolidation of landslide slopes and the clearance of polluted areas as well. No open trenches along the HDD profile are necessary and when the HDD is completed all the working areas are restored.įor the small pipes the reaming phase can be avoided, moreover both the rigs and working areas can be reduced and the time of work too. The drilling operations are usually carried out using some drilling fluid, which composition depends on the kind of terrain to be crossed this fluid (mud) generally consists on water and bentonite (or polymers). The last phase regards the pulling back of the pipeline string, made of the welded pipes.Then a reamer, with suitable diameter according to the diameter of pipelines to be laid, is secured to the pack of pull rods and is pulled back from the exit to the entry point enlarging the pilot hole.When the pilot gets the designed exit point this phase is completed First of all a pilot drilling has to be carried out through the introduction into the entry point of drill rods with in front a drilling head.The drilling profile is designed by a dedicated project and during the work can be followed thanks to a guided system, often a magnetic guided system, in order to avoid natural and artificial obstacles and get the designed goal, working from the Rig side (Rig is called the machine that performs the drilling operations) that is close to the entry point. These pipes can be used for a lot of underground services like water transport, oil & gas transport, telecommunication cables and so on. The pipes diameter varies from 40 mm up to 1600 mm. Through the HDD Technology is possible to lay polyethylene, steel and ductile iron pipes along a drilled profile.
