Pointing mortars

Pointing mortars are stiff to malleable in consistency. The grain-size is < 2mm. Pointing mortar is used to grout joints in brickwork and to grout joints between two sections of pipe, as well as replacing corroded or washed out grouting. Joints between manhole shaft rings are sealed with 2 to 4 cm depth of jointing mortar. Cavities, small defects affecting only a limited area, and cracks can all be repaired with pointing mortar. In man-accessible sewers, laterals can also be jointed with pointing mortar. Its uses overlap those of repair mortar.
