Methods used include drilling, blasting, pigging, sawing, hydrobags, thrusters, dredging, suction dredging and environmental dredging.
Dredging consists of digging masses under water where the masses can be clay, silt (deposited sludge), sand, all types of moraine masses and rock masses that have been blasted out under water. Mud masses will usually be dug or grabbed up in a split hopper barge and then towed to an approved dump site for disposal or transported to land.
Any dredging or dumping operation requires permission from the government. Feel free to contact us for some guidance.
