  • METHOD FOR DRAINING SOIL USING A FILTRATION MEANS
    Publication number: 20140341652
    Abstract: The present invention concerns a method for draining soil such as dredger sludge using a filtration means, comprising the steps of: forming a support layer for supporting a quantity of soil, placing the filtration means on the support layer such that the periphery of the filtration means essentially connects to the support layer and forms a space between the filtration means and the support layer, filling the space between the filtration means and the support layer with soil, draining the soil under the influence of gravity, removing the filtration means from the at least partly drained soil and removing the at least partly drained soil from the support layer.
