Typical Brick Masonry Issues

Periodically check exposed masonry for signs of degradation in the mortar as well as cracking, spalling, bending (vertical bulges), sweeping (horizontal bulges), leaning, and bulges. Make a distinction between the load-bearing and non-load-bearing walls before starting a thorough masonry assessment. Typically, this can be done by looking at the beams and joists in the basement, crawl space, or attic of the building. Also take note of the type of masonry, such as solid or cavity, non-structural brick, or stone veneer, used in the walls.

Large motions typically result in cracking, even though masonry can bend elastically over time to allow modest quantities of movement. The masonry units themselves or the mortar joints may develop cracks. A number of issues can cause cracking, including uneven foundation settlement, drying shrinkage, expansion, and contraction due to changes in the surrounding temperature and moisture, inadequate support over openings, the effects of freeze-thaw cycles, corrosion of iron and steel wall reinforcement, uneven movement of different building materials, salt expansion, and bulging or leaning of walls.

Aside from issues brought on by differential settlement or earthquakes, structural issues are typically observed at openings, beneath roof eaves, or in places where the structure is being overloaded. Rather than along the weaker mortar joist, the masonry units will display cracks in these situations via the units themselves. Deflection or failure of the lintels or arches that bridge the openings are common causes of displacement problems, as are cracking or displacement of the masonry around openings, as well as displacement brought on by overstressed masonry units. As the wood sags or deteriorates, older masonry walls with wood lintels will start to split. Lintels made of iron and steel that deflect or rust with time also crack. Replacing damaged parts and rebuilding the vicinity of the opening are frequently required to resolve such issues.

There can also be a leak in the roof. When this happens, carefully inspect the roof structure to determine whether a failure occurred as a result of improperly positioned ceiling rafters or a lack of rafter ties. If this is the case, more horizontal ties or tension members must be installed, and the roof may need to be pushed back into position. The masonry damage can then be fixed.

Repair comes next when the type and cause of cracks have been identified. Minor or aesthetic repairs come after structural repairs. Repointing mortar joints is frequently necessary, but it must be done carefully and is best left to experts who are skilled with traditional masonry methods. Too frequently, incorrect pointing causes more harm to historic brick buildings than the majority of other treatments combined. And the harm is not just superficial. To match the qualities of the current mortar, care must be given. Leave this job to an expert Local Chimney Cleaning Service Venice to avoid any further damage to your chimney.

The term “settlement” refers to a phenomenon in which the earth surrounding your home shrinks, which is another way of expressing that it loses strength, and is the root of the majority of masonry-related problems. Strong ground pressure from the area around the building’s base is necessary for proper alignment. This pressure exerts additional strain on the brick-and-mortar if it is reduced. They fail because neither is naturally bendable.
