A structure for protecting a substrate. The structure comprises an inner tie coat layer which can bond to the substrate, a geopolymer foam layer, and an outer protective layer. The geopolymer foam layer is the reaction product of a mixture comprising an aluminosilicate source, an alkali activator, reinforcing fibres, and a plurality of microparticles.

A polyurethane composition includes a polyol component (A) including at least one polyol, a hardener component (B) including at least one polyisocyanate and glass microspheres along with the other optional additives and fillers. Further a method for applying polyurethane composition to create floors. The polyurethane composition is suitable as a flooring material.
