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 free of phenol and formaldehyde;
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 lignosulfonate lignins having a carboxylic acid group content of 0.03 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins,
a component (ii) in form of one or more cross-linkers.
