Method for the preparation of tile modules using lightweight clay material, comprising the steps: producing a formable clay body, wherein the step of producing the formable clay body comprises: a) producing a lightweight clay material as a component and aggregate for tile modules and their production, comprising the steps: producing a formulation comprising: a clay material suspension, a water-repellent agent, a foaming agent and, optionally, a binder and/or admixture, wherein the clay material suspension comprises clay-containing materials as well as water and a content of clay-containing materials of 65 to 98 wt% of the solids content, and the water-repellent agent serves to stabilise the lightweight clay material in relation to aqueous media, producing a clay foam from the formulation, and drying the clay foam, b) producing a bonding clay, preferably a bonding clay adjusted to be highly plastic to paste-like, by mixing clay-containing materials, water and, optionally, at least one extrusion aid, and c) mixing the bonding clay, the lightweight clay material and, optionally, at least one sintering aid, wherein the added content of the lightweight clay material amounts to 40 to 90 vol%, and the added content of the bonding clay amounts to 10 to 60 wt% or the added content of the lightweight clay material amounts to 5 to 40 vol% and the added content of the bonding clay amounts to 60 to 95 wt%, forming the formable clay body into tile modules, drying the formed tile modules, firing the dried tile modules, and finishing the fired tile modules.
