Abstract
The present invention relates to a method of draining water comprising the steps of: providing a water drainage device, wherein the water drainage device comprises man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition; positioning the water drainage device in contact with the ground, wherein the water drainage device absorbs water and releases water to a recipient wherein the aqueous binder composition prior to curing comprises; a component (i) in form of one or more oxidized lignins; a component (ii) in form of one or more cross-linkers.
