JOINT DESIGN GEOMETRY

The width of the joint should be a minimum of 4 times the anticipated movement. Joints with cyclic
movement should have a width to depth ratio of 2:1. Minimum depth of the sealant should be maintained as
recommended below :

10mm for all porous surfaces.
20mm for joints exposed to traffic & hydrostatic pressure.
5mm for impervious surfaces such as metal, glass, etc.
