TerraCarta has developed an unique system in order to locate and map pipes placed through horizontal directional drilling (HDD) as well as underwater cables. Not just the actual technical steps we take, but also communicating with utility owners, capturing evidence and an insurance that aligns with the risks involved have been developed throughout the years, to ensure that we can locate HDD pipes efficiently and systematically.
For example, during dredging activities or applying sheet piling, it is of the utmost importance to know the exact positions of HDD pipes and underwater cables.
If an HDD is planned, it is also important to map the utilities that cross the path of drilling. It would not be the first time damage to utilities caused by directional drilling resulted in an outage. Of course, this must be prevented. Throughout the years, TerraCarta has built up a lot of experience through locating and surveying HDD pipes. Our clients for these are the biggest utility owners and water construction contractors in the Netherlands.
