Building materials

Adhesives, sealants and mortars are usually the cheapest materials in a quotation and the first to be substituted with ‘equivalents’. Yet they are the very things that hold the rest in place: a tile coming loose on the balcony, a joint cracking after the first winter, or a concrete repair flaking off are not due to the tile or the concrete itself. That is why the choice depends on the performance class, not the name: C2 tile adhesive with S1 or S2 deformability for outdoor areas and heated floors, R3 or R4 repair mortar for load-bearing elements, and a sealant with movement capacity corresponding to the width and movement of the joint. Trade supply with technical support: tile adhesives, sealants and bonding agents, repair and structural reinforcement materials, mortar and concrete additives, paints and glass blocks, with a declaration of performance and CE marking, class selection based on application and nationwide delivery to the building site.
