In all masonry walls (brick, stone or block), the exposed face of the mortar joint is subject to gradual erosion due to rain, wind and wind- driven dust, grit and other natural elements. These elements take there toll over many years and start to break down the pointed mortar face. Once the exposed face of the mortar has receded behind the outer wall face the potential for damages is greatly increases. Now the mortar has eroded behind the face this now leaves a small channel at the face of all joints. This channel is where any rain water will happily sit and soak into the bricks and mortar, slowly making its way inwards. This formed channel is now a prime position for frost damage. The water that’s sits there will freeze, expand and eventually crack or chip the faces of surrounding bricks or stone. At some point the joints become so worn that water can penetrate and saturate the wall. The decision to repoint is most often related to some obvious sign of deterioration, such as disintegrating mortar, cracks in mortar pointing, loose bricks or stones or even worse damp walls, or damaged plasterwork internally.
