POINTING is the mortar between bricks. A more accurate definition is that it is the visible edge of the mortar-joint.
Repointing is the process of repairing damaged mortar in brick work, roof tiling or masonry. Broken, cracked or otherwise damaged mortar is the primary entry point for moisture into the home. Once inside, the moisture continues to do damage, so repointing is a necessary part of home maintenance.
Ridge tiles (also called capping tiles) are the most important tiles on the roof. As the “first line of defence” against water, ridge tiles must be cemented into place and “pointing” applied to the exposed edges of the tiles. Traditionally, repointing was done with a sand and cement mixture, but today, flexible repointing materials are used that minimise the problems of shrinkage and cracking that commonly occur with cement.
