5 | MECHANICAL COUPLING WITH GEORETE AND GEO WALL PLUGS
In the presence of critical installation bases with insufficient mechanical strength to support the wall covering, Geopietra® experience advises against using treatments or pitting techniques as they cannot guarantee the integrity of the solution over time.
The best solution is mechanical anchoring using a layer of Geocoll® adhesive with a minimum thickness of 3/4 mm, in which special reinforced Georete can be embedded and secured to the loadbearing structure using stainless steel (external use) or galvanised (internal use) Geo wall plugs.
Thanks to its high-quality anti-alkaline finish, Georete provides excellent resistance against alkalis, whereas the large mesh (15x15 mm) enables the perfect adhesion of the mesh in the adhesive, guaranteeing the integrity of the reinforced layer. Unlike metal products, it also limits the consumption of adhesive, reduces thicknesses, adapts to the thermal expansion of the material in which it is inserted, is not subjected to oxidisation, and does not create electromagnetic fields.
Using a smooth trowel apply a layer of Geocoll® adhesive which is 2/3 mm minimum and of reasonably soft consistency (8.5-9 litres of water per 25-kg bag). With very absorbent bases dampen them first then apply the layer when there is no film of water remaining. With dirty or deteriorated bases clean or remove fragile parts.
