Separating wall junction methods with external cavity walls
Separating walls must be joined to the inner leaf of external cavity walls using either bonded or tied methods, with specific requirements for load distribution and structural connection at each junction.
The separating wall should be joined to the inner leaf of the external cavity wall by one of the following methods –
(a) Bonded. The separating wall should be bonded to the external wall in such a way that the separating wall contributes at least 50% of the bond at the junction (see Diagram 2.6).
(b) Tied. The external wall should abut the separating wall and be tied to it (see Diagram 2.7).
