At TerraCarta, we specialize in locating, surveying and recording sinkers and horizontal directional drilling. Detection is essential in water works, road works and rail construction projects, where underground pipelines are often laid at great depths. Thanks to our advanced detection techniques and years of experience, we accurately map the exact location of this underground infrastructure.
When planning horizontal directional drilling, it is crucial to accurately map the location of existing cables and pipelines in the path of the drilling. This prevents failures and damage to underground infrastructure. TerraCarta has extensive experience performing directional drilling for clients such as ProRail, VolkerWessels, Waternet, and Stedin. With our expertise, we minimize risks and ensure that your project proceeds without delays.
In projects such as dredging or sheet pile installation, it is often very important to know the exact location of steered bores and culverts. TerraCarta offers comprehensive services to locate, survey and record these structures. Our experience in these types of projects makes us the ideal partner for both contractors and grid operators.
We use advanced detection techniques such as ground penetrating radar, radio detection and test trenching to locate the head of drilling. The material of the pipes plays an important role in the detection method. For metal pipes, radio detection is used, while for plastic pipes, ground penetrating radar is used or a tendon is installed for radio detection. When these methods are not sufficient, we apply gyroscopy to check the pipe.
TerraCarta has developed a water jet system that performs directional drilling to great depths without problems. This system, which operates on water pressure, makes it possible to accurately survey and map boreholes, even at great depths.
