In cavity wall construction it is imperative to tie both walls together as this assists in holding the walls parallel and together to help strengthen the wall in stressful situations such as earth movement or high winds.
In coastal conditions the ties must be able to cope with the harsh environment and made of material that is able to resist corrosion.
The ties used for brick cavity work must:
- be of a minimum classification medium
- be used at the cavity width at which
it passed the AS/NZ 2699 & 3700
- have a corrosion resistance rating
adequate for the environment in which
it is to be used; and
- be installed in accordance with the
appropriate spacings within the
environment classifications location
which they are being constructed.
