The thin joint mortar system

The Thin Joint Mortar system is a flexible building technique that allows walls to be built more quickly than using conventional mortar.

The system can be used in commercial buildings as the inner leaf of cavity walls, solid external walls, separating walls and for internal loadbearing and nonloadbearing infill partitions.

Tarmac has specifically developed Thin Joint Mortar for use with its BBX and other blocks. The mortar is spread on the blocks using a serrated applicator.

The purpose of this tool is to lay the mortar on the bedding surface in a series of ribbons, similar to the process of applying tiling adhesive, which controls the amount of mortar, giving a consistent bed depth.

This not only ensures that the joints are fully filled, but means that less levelling of individual blocks is required.
