How this node works
A stone floor must be able to move: expansion joints divide it into fields and run right through the slab, the adhesive and the screed, filled with an elastic sealant. Without them, the screed’s shrinkage and thermal movement crack the slabs.
Key points
- Stone slab
- Movement joint (elastic)
- Adhesive
- De-coupling layer
- Screed
- Structural slab
