River dredging

River dredging is a form of river restoration and river maintenance. Over time, sand, silt and debris (branches, logs, waste) flow downstream. This is a natural phenomenon, which happens due to weathering, erosion and rivers carrying sediments. If not maintained, the materials accumulate and create a blockage. Consequently, this restricts natural river flow and makes the waters very shallow. As a result, rivers become inaccessible to larger ships. Additionally, during heavy rain season, restricted river flow can cause flooding. Flooding may result in major property damage, have negative impact on local businesses, and even be life threatening.

River dredging is therefore necessary to maintain natural river flow and appropriate water depth to minimize risk of potential disasters.

River Dredging equipment

Dredging equipment for river dredging can include auger dredgers and cutter suction dredgers depending on the conditions on site. Some of the factors to consider are river currents, water depth and materials to be dredged. In addition to different dredger types and sizes, we offer dredging equipment customization (e.g. increasing swing length, extending dredging depth) according to project requirements.

Our standard dredger series includes one truck transportable ECO Cutter Suction Dredgers and one container transportable ECO Auger Dredgers. Compact ECO dredger design allows for easy and economic dredger transport to project site. In addition to this, the dredger can be easily removed from water and stored for later use.
