Geotextile tubes can be used to dewater materials such as sludge, sediments or residues aiming at reducing their moisture contents to acceptable levels. The tube filling process can be carried out using one or several filling stages, and the number of stages can influence the tube behaviour in terms of dewatering rate, final shape and geotextile strains...

Filtered tailings is the disposal technology that is most likely to yield an unsaturated state of the tailings. Such state has important benefits. A dam to contain the mine wastes is no longer needed, the risk of polluting seepage is minimized, and liquefaction of tailings is prevented. Filtering also allows most of the water mixed with the tailings to ...

The use of geotextile closed systems for the dewatering of sludge is a new technology that has been used in recent years in Brazil and globally. This technology has relevant technical and environmental advantages. The variables that influence the operation and evaluation of the efficacy are under constant investigation by the scientific community. This ...

The Boston Central Artery/Tunnel (CAT) project consists of some 200 lane-kilometers of bridges, tunnels, and surface roadways. The central part of the project involves constructing two directions of multi-lane roadway to depths exceeding 30 m beneath the existing city by means of the slurry wall technique. The resulting walls, called Soldier Pile Tremmi...
