6.0 Installation

This section provides guidance
on protecting cast stone during
construction, laying, bedding,
joining, cutting, the recommended
grade of mortars for cast stone
products, and casting-in any
required fixings.

Cast stone units should only be installed by suitably qualified personnel.
During construction, the units should be protected at the end of each day
and it is advisable to protect finished work.

The fixing of cast stone should be considered at the design stage so that
any required fixings can be cast-in during production. Your UKCSA supplier
will be able to advise on the most cost-effective solutions.

Cast stone units should be designed to minimise on site cutting. They
are typically designed to be fixed with joint sizes of between 5-10mm and
should be laid and adjusted to final position while the mortar is still plastic.
It is vital to specify the correct mortar designation, which is often different
to that used for the surrounding brickwork. Mortars containing lime give a
stronger bond than those containing air-entrainment.
