ABSTRACT A process is disclosed for manufacturing concrete products such as panels suitable for building construction. A surface reinforcing layer of porous material is arranged in a concrete form. This material comprises a fabric or moisture- resistant paper and is resistant to alkaline conditions. An inner surface thereof is coated with a polymer so that the applied polymer penetrates the layer. A cementitious composition is cast over and onto the layer of material in the form. The composition has a consistency to enable partial substantial penetration of the layer of material and the amount thereof is sufficient that a major portion lies on top of the layer. A sheet of porous material that is resistant to alkaline conditions is coated on one surface with polymer and this sheet is placed over the exposed surface of the cast composition so that the coated surface lies against the cementitious composition and enables the latter to penetrate partially the sheet. The formed product is then cured and removed from the form.
