Thin joint masonry
Offsite residential construction, Glossary of terms, published by Buildoffsite in 2018, states in relation to thin joint masonry: ‘While not part of the offsite spectrum it is included in Homes England definition of MMC. It allows the depth of the mortar to be reduced from 10 mm to 3 mm or less, resulting in faster laying and improved productivity, particularly on long runs of walling. Construction speed can be further increased by around 13 per cent using large-format concrete blocks, which have a face size equivalent to two traditional concrete blocks. The mortar cures rapidly, achieving full bond strength within one to two hours, eliminating the problem of ‘floating’ and enabling more courses to be laid per day.'
It defines thin joint masonry (pre-assembled) as: ‘The use of thin joint ‘glued’ blockwork pre-assembled offsite into panels that are then delivered to site and installed by crane in one operation. Panels may be single skin or cavity construction complete with insulation.’
