Beach Nourishment
Beach nourishment dredging is a process used to replenish or restore eroded beaches by depositing sand or other sediments from underwater sources onto the shore. This technique is employed to counteract the natural erosion of beaches, often caused by factors such as wave action, storm surges, and human activities.
Dams
Overtime dams can collect sediment and lose their capacity. This creates two problems loss of water volume which is a problem if the dam is used for irrigation and secondly they can become overrun with vegetation due to the shallow water.We can remove the built-up sediment which increases the dams capacity and creates enough depth that most vegetation cannot grow in.
Quarry
Quarry dredging involves the extraction of materials, typically sand, gravel, or other aggregates, from underwater deposits in a quarry setting. Dredging is employed in quarries to obtain valuable construction materials for various purposes, including concrete production, road construction, and building projects.
Channel / Navigational Dredging
Channel dredging involves the removal of sediments and other materials from navigable waterways to maintain or improve their depth, width, and overall navigability. Channels are essential for maritime transportation, and dredging ensures that waterborne vessels can navigate safely and efficiently.
Settling/ Tailings Pond
Dredging tailings ponds involves the removal of accumulated tailings material from ponds used in mining operations. Tailings are the residues left over after the extraction of valuable minerals from ore, often in the form of a slurry.The tailings are typically stored in large ponds or impoundments. Over time, these ponds can accumulate sediments, settleable solids, and other materials, reducing their storage capacity and potentially posing environmental risks. Our dredges can be employed to manage and remediate these tailings ponds.
Geo Tubes
Geo tubes are placed in a designated area, and dredged sediments are pumped into them. The geotextile fabric allows water to drain out while retaining the solid materials inside the tube.Uncontaminated material can be left to dry and then reused as either fill or top dressing. Contaminated material once dried can be trucked away to a waste facility. This dewatering process significantly reduces the volume of material that needs disposal, making it more cost effective and environmentally friendly.
Marina Dredging
Marina dredging projects are based on the specific needs of the marina, considering factors such as water depths, sediment composition, and the types of vessels using the facility. Additionally, regular maintenance dredging may be necessary to address ongoing sedimentation and maintain optimal conditions for marine activities.Coastal Dredging Services own dredges that have a small enough footprint to be able to fit into small shallow marina berths and achieve results with minimal disturbance to the marina and moored vessels.
Effluent Ponds
Effluent pond dredging involves the removal of accumulated sediments, sludge, and other materials from effluent ponds or lagoons. Effluent ponds are commonly used in various industrial and wastewater treatment processes to store and manage liquid waste, often known as effluent. Over time, these ponds can experience sedimentation, which can reduce their storage capacity and impact their effectiveness. Dredging is employed to maintain the functionality of these ponds.
