A method for the wet production of a superabsorbent material, comprising the formation of an aqueous saline solution with a concentration of 0.01 - 4.5 N of ionic salt and pH from 0 to 6.0 or from 8.0 to 14.0 by the addition of a strong acid or strong base； the dispersion in the saline solution of a water superabsorbent polymer (SAP) component selected among the polymers comprising at least one acidic resin not completely neutralized in case of acidic saline solution and/or comprising at least one basic resin not completely neutralized in case of basic saline solution； the implementation of a first web by stratification and deposition under vacuum suction onto the mesh screen belt deposition section of the SAP dispersion； washing out of the web with basic solution up to the desired level of neutralization of the acidity for SAP dispersions in acidic saline solutions or with acidic solution up to the desired level of neutralization of the basicity for SAP dispersions in basic saline solutions； washing out of the web with water and suction and drying up of the web. The relationship between pH and salt concentration is such that it causes a water absorption in the SAP equal to or less than about 30.00 g
