SEVERELY EXPOSED BRICKWORK

Brick walls are attractive and durable when designed correctly and built with appropriate materials. This technical guide caters for those seeking to achieve long-lasting results in their external works (such as freestanding garden and retaining walls and chimneys), which regardless of location, should always be considered to be severely exposed.

Whilst geography is important when designing the walls of buildings (see the rainfall and frost exposure maps in the NHBC technical manual) it is recommended that all external works be designed and built in accordance with best practice for severely exposed brickwork, to minimise the risk posed by frost attack.

Paving applications are not covered in this note as BS EN 771-1 bricks are not intended for these uses. Clay pavers to BS EN 1344 are available.

This guide assimilates the experience and expertise of our members and takes account of some evidence (recent winters) that suggests changing climatic conditions i.e. wetter spells preceding severe drops in overnight temperature.
