Thin joint technology

Thin joint masonry is accepted as a Modern Method of Construction (MMC). The combination of large format blocks (440 x 330mm) and thin joint mortar (3mm) give a variety of benefits:

  • Increased speed of construction
  • Reduced waste and mess
  • Faster set rate
  • Improved air-tightness
Thermalite.

The process is slightly different to standard blocklaying, with a mortar scoop used to apply the thin bed of mortar rather than a trowel. The special mortar is created by whisking powder and water to a creamy consistency with a drill attached to a paddle mixer. The nature of the blocks ensures cuts can easily be made with a masonry handsaw, while helical cavity wall ties are simply hammered in to suit.
