Profile: Mersing Construction & Engineering Sdn. Bhd. specializes in trenchless construction technology. We are fully equipped with modern micro-tunneling and horizontal directional drilling equipments. Our other activities include infrastructure and drainage works such as river diversion, construction of box culverts & line drain. Horizontal directional drilling offers minimal environmental disturbance during project construction. Depending on soil conditions, our drilling rigs have the capacity to drill up to lengths of 2000 m with a diameter of 1000 mm. Directional drilling is used to install pipelines carrying oil, natural gas, petrochemicals, water, sewerage and other products as well as conduits for utility services, electric & fiber optic cables under rivers, busy streets, highways, railroads, airport runways, shore approaches, islands, areas congested with buildings, pipeline corridors, future water channels & other locations where trenchless installation methods are applicable. The pipe bursting system is a new technology used to replace existing water, sewer or gas mains that have become faulty due to age, corrosion, tree roots infestation, pipe settlement and misaligned pipe joints. With this system, new pipes can be replaced by being pulled in directly after the old pipe has been fragmented and displaced into the surroundings. Open trenches are no longer required to complete these processes. The system consists of a rig with hydraulic cylinder, a hydraulic power pack and bursting rods with bore head for bursting & various diameter expanders for pulling in the new pipe. This system can be easily set up for immediate action and requires only two operators to operate it. A high replacement productivity, which can exceed 200 m a day, can be achieved with this system.
