Betonestriche

Betonestriche, often translated as concrete screed, refers to a layer of concrete or cementitious material applied to a subfloor. Its primary purpose is to create a level and smooth surface for subsequent flooring installations such as tiles, wood, laminate, or carpet. Betonestriche also contributes to the structural integrity of the floor, providing a stable base and distributing loads.

The composition of betonestriche typically involves cement, sand, and water, with aggregates of varying sizes. Additives may be included to enhance properties like workability, strength, or drying time. The thickness of the screed layer can vary depending on the application, but it generally ranges from a few centimeters to over ten centimeters.

Application methods for betonestriche can be traditional, where the mixture is spread and leveled manually, or pump-applied for larger areas or when faster installation is required. Curing is a crucial stage, allowing the screed to gain its designed strength and preventing shrinkage cracks. Proper curing often involves keeping the surface moist for a specified period.

Betonestriche can be laid in various ways: bonded directly to the subfloor, unbonded on top of a separating layer like building paper or a damp-proof membrane, or as a floating screed incorporating thermal or acoustic insulation. The choice of method depends on the subfloor material, structural requirements, and desired performance characteristics of the finished floor.
