lastrazione

Lastrazione is a term used in Italian technical literature to describe the fabrication of layered materials by assembling flat slabs or sheets into a single composite. The term is common in construction, architecture, and materials science contexts and derives from lastra, slab.

The process typically involves preparing the substrate or base, cutting and sorting slabs to fit tolerances, aligning layers to optimize contact, applying a bonding matrix or adhesive (such as epoxy, cementitious slurry, or polyurethane), and curing under controlled conditions. Finishing steps may include surface leveling, sealing, and weatherproofing. Applications include architectural cladding, floor panels, countertops, and lightweight structural laminates; it also enables incorporation of recycled or heterogeneous materials where monolithic pouring is impractical.

Etymology and variants: the word derives from lastra, slab, and the suffix -zione indicating an action or process. Related terms include lastratura, used for the act of laying slabs, and lastrato, referring to a slab that has been laid. In some contexts, lastrazione may be described together with laminated or composite formulations to emphasize the layered nature of the material.
