Mortar joints are an essential component of any brick structure. They hold bricks together, distribute weight evenly, and protect masonry from moisture intrusion. Over time, however, mortar can begin to crack or deteriorate due to various environmental and structural factors. When this occurs, experienced masonry contractors near me Arlington Heights are often needed to restore the integrity of the wall.
One major cause of mortar cracking is natural weather exposure. Rain, wind, and temperature changes slowly wear down mortar joints. As mortar ages, it loses flexibility and becomes more vulnerable to cracking.
Another common cause is freeze-thaw damage. Water that enters small cracks in mortar expands when it freezes, placing pressure on the surrounding material. Repeated freezing and thawing cycles gradually weaken the mortar, eventually causing visible cracks.
Structural movement can also lead to mortar damage. Buildings naturally settle over time, and slight shifts in the foundation can place stress on brick walls. This stress often appears as cracks in mortar joints or along brick surfaces.
Poor installation is another factor that may contribute to early mortar failure. If the original mortar mixture was not prepared correctly or applied improperly, it may deteriorate faster than expected.
To repair cracked mortar, masonry contractors typically perform tuckpointing. This process involves removing deteriorated mortar from the joints and replacing it with fresh mortar that closely matches the original color and texture.
In some cases, bricks surrounding the damaged mortar may also require replacement. Masonry contractors carefully remove damaged bricks and install new ones while preserving the structural stability of the wall.
Timely repairs are essential for maintaining strong masonry structures. By addressing mortar cracks early, homeowners can prevent moisture infiltration and structural damage. Professional masonry contractors ensure that repairs are performed correctly so brick structures remain durable and visually appealing for many years.
