Repointing is needed when the existing mortar is deteriorated and decayed; basically like white dust falling out of the mortar joints. This is caused by weathering and decay that cause voids in the joints between masonry units, usually in bricks, allowing water to enter. This can cause significant damage through frost and salt dissolution and deposition.
Brick Pointing Team’s Repointing Service
Our professionals are experienced in the process of repointing which included examining the structure, establishing materials and testing panels. We remove old mortar with a vacuum system to ensure dust free operation. Then professionally, fill in the appropriate new mortar finished to the original style. We finish with a high pressure wash.
History of Repointing
The first mortar was made with lime and sand. In the early 20th century masons started using Portland Cement, a strong, fast drying cement. Masonry cement started to be used in the 1930s, which is a combination of Portland cement and ground limestone.
