ABSTRACT:
A process for manufacturing a multilayer building panel in which one layer s a main layer comprising a binder and a reinforcing additive, and another layer contains a binder and a reinforcement such as a mat includes depositing the various layers such that one layer is deposited with an excess of water for hardening, and another with a deficiency, so that the water is caused to migrate between layers and creates a transition layer providing a gradual and continuous transition in composition between the layers.
