As a form of ‘wet’ construction, masonry needs time to dry out - TopicsExpress

As a form of ‘wet’ construction, masonry needs time to dry out between blockwork ‘lifts’. As a result, masonry is likely to be slower than timber frame construction. The tall, slender walls in cavity construction may also be prone to settlement cracks. There are also fears over the cleanliness of the cavities, the fear being that if too much mortar is allowed to drop on cavity ties above the damp proof course level, or besides the insulation bats, bridges could be formed that might transfer damp to the inner skin. It should be remembered, however, that where a timber frame structure is clad in brick or blockwork, the cleanliness of cavities is also an issue.
