LAYING ON SCREED WITH ADHESIVE

The advanced technical features of the 2 cm (3/4”)-thick L’Altra Pietra collections, combined with an adhesive laying technique on screed, allow users to create perfectly stable and exceptionally hard-wearing surfaces. L’Altra Pietra slabs used with this solution can withstand both moving and parked vehicles. Ideal for heavily frequented areas, in particular for squares, pavements, or ramps.

Expansion joints are necessary and joints must be filled with cementitious grout.
