TUCKPOINTING
 |
|||
Tuckpointing is a Masonry repair technique used to restore and maintain the integrity of brickwork or stone walls. It involves removing deteriorated mortar from the joints and replacing it with new mortar that matches the original in both composition and appearance. This process plays a crucial role in the conservation and long-term maintenance of heritage buildings, as well as modern masonry structures.
It restores the original look of a wall, which is especially important for heritage buildings where visual integrity matters. From a maintenance perspective, tuckpointing is a preventive measure that avoids more serious damage like brick spalling or structural failure, extending the lifespan of the building and reducing future repair costs.
The Trade of Tuckpointing: Tuckpointing is a skilled trade within the field of masonry. Craftspeople, often called tuckpointers or pointing masons, must understand mortar chemistry, cutting and filling techniques, color and texture matching, and working safely in challenging conditions. In heritage conservation, knowledge of historical methods and materials is essential to maintain authenticity.
Materials Used: The most critical material is the mortar. Lime-based mortars are often used in historic restoration, while modern structures may use Portland cement-based mortars. Choosing the right mortar is essential to avoid damaging the surrounding masonry. Pigments may be added for aesthetic reasons, particularly in traditional tuckpointing, where a contrasting fine line is used to mimic narrow joints. Aggregates like sand must be selected for size, color, and texture to match the original material.
