Effect of Artificial Ageing on Sprayed Waterproof Insulation Based on Polyurethane Elastomer
Ground water, rain and other environmental effects are important moisture sources which affect the durability and performance of basements, roofs, underground and other building structures in the direct contact with moisture. Waterproof materials such as bitumen sheets, polymeric foils and membranes provide basic protection of constructions against harmful moisture action. However, in some cases, the applicability of commonly applied waterproof insulation systems is limited as for example in tunnel constructions with complicated geometry or in areas with unstable subsoil. Here, advanced types of waterproof materials find use. On this account, sprayed waterproof coating based on polyurethane elastomer designed for protection of complicated shapes and extremely mechanically loaded structures is experimentally researched in the paper. The obtained data give clear evidence of a good resistance of studied coating against artificial accelerated temperature ageing. The studied material has high resistivity to impact and ductility. The interaction of accelerated aging and impact loading has no effect on vapor-and waterproof function of the insulation layer. In addition, polyurethane elastomer provides a sufficient adhesion to the typical buildings materials, such as concrete, ceramic brick, etc.
