Gavazzi fiberglass meshes have been designed for the reinforcement of low thickness screeds and are an alternative to metal reinforcements.
The screed is a layer of mortar of varying thickness applied to a concrete surface or to insulation panels.
Its composition based on water and cement during the drying period makes it prone to cracking due to shrinkage and its poor tensile strength. In fact, chemical / physical reactions develop (especially in the first 28 days) that generate internal tensions that create the aforementioned cracks.
This is problematic for subsequent surface applications, such as for example the laying of tiles or resins; therefore to obtain a quality screed it is essential to use a reinforcement armature.
