Joint Design

The joint dimensions must be designed to suit the movement capability of the sealant. The joint width must be ≥ 5 mm and ≤ 15 mm. The joint depth must be ≥ 5 mm and ≤ 10 mm. A width to depth ratio between 2:1 to 1:1 must be maintained (min / max examples, see table below).

Joint depth [mm]

max. 15

max. 10

All joints must be correctly designed and dimensioned in accordance with the relevant standards and codes of practice before their construction. The basis for calculation of the necessary joint widths are the type of structure, dimensions,  technical values of the adjacent building materials, joint sealing material, and the specific exposure of the building and the joints.

For larger joints contact Sika Technical Services for additional information.
