The joint width must be designed to suit the joint movement required and
the movement capability of the sealant. The joint width shall be ≥ 10 mm
and ≤ 50 mm. The joint depth shall be ≤ 10 mm. A width to depth ratio of
2:1 must be maintained.
All joints must be correctly designed and dimensioned in accordance with
the relevant standards, before their construction. The basis for calculation
of the necessary joint widths are the type of structure and its dimensions,
the technical values of the adjacent building materials and the joint sealing
material, as well as the specific exposure of the building and the joints.
Note: Test certificates should be referred to while designing a firerated joint
