Common Problems In Masonry Construction: Water Leaks, Dislodged Bricks, And Cracks
In the realm of masonry construction, several common problems can plague structures, leading to aesthetic and structural issues. Water leaks, dislodged bricks, and cracks are among the most prevalent concerns faced by builders and property owners alike. These issues can compromise the integrity of the entire masonry system, posing safety risks and requiring immediate attention.
One of the main problems in masonry construction is major water leaks. When water infiltrates the masonry, it can cause extensive damage, leading to spalling and broken masonry. The continuous exposure to water weakens the bonding of the materials, resulting in the deterioration of the structure. In addition to the visible disintegration of the masonry, water leaks can also lead to mold growth, which can negatively impact indoor air quality and pose health hazards to residents.
Another common problem in masonry construction is the dislodging and falling of bricks. This issue is often caused by improper mortar application or the use of low-quality materials. When bricks become loose, they not only compromise the overall aesthetics of the building but also pose serious safety risks to anyone in the vicinity. The falling bricks can cause injury or property damage, emphasizing the importance of addressing this issue promptly.
Cracks are also a prevalent problem in masonry construction. These cracks can appear in both bricks and the masonry itself, indicating underlying structural issues. Cracks can occur due to a variety of factors, including settlement of the foundation, thermal expansion and contraction, and poor construction practices. If left unaddressed, these cracks can further propagate, leading to more severe damage and potential instability of the structure.
Importance Of Mortar Joints And Choosing The Right Type
Mortar joints play a crucial role in solidifying masonry structures and repelling water. Choosing the correct type of mortar is crucial for the repair and maintenance of masonry construction. Different mortar types have varying levels of strength and permeability, so it is essential to consult with professionals to ensure the correct mortar is selected for each specific application.
Using the wrong type of mortar can compromise the integrity of the masonry, leading to increased water permeability and a higher likelihood of future damage. The mortar joints should be properly proportioned and applied to create a strong bond between bricks or other masonry units. Expert masons understand the importance of matching the existing mortar to maintain the structural integrity and aesthetics of the masonry.
Failed Joint Sealants And The Need For Annual Inspections
Joint sealants play a crucial role in preventing water intrusion and subsequent damage to masonry structures. However, it is essential to acknowledge that, over time, these sealants may fail, resulting in water entry and further deterioration of the masonry construction. This deterioration often occurs due to the expanding and contracting forces exerted on the sealants during freeze and thaw cycles, particularly in winter.
To prevent such issues, it is highly recommended to conduct annual inspections to assess the effectiveness of joint sealants. These regular examinations can quickly identify any signs of deterioration or failure, allowing for timely repair or replacement. Neglecting to inspect and maintain the joint sealants can lead to costly repairs and potentially compromise the structural integrity of the masonry. Ensuring the necessary upkeep of joint sealants is therefore paramount.
Understanding Efflorescence And Preventing Damage
Efflorescence, the white powdery substance that appears on the surface of masonry, is a common issue that can detract from the overall appearance of a building. Efflorescence occurs when water in masonry brings salts to the surface as it evaporates. The salts then crystallize, leaving behind a white residue. This phenomenon is not just a cosmetic concern; it can also indicate underlying water intrusion issues that can lead to more serious masonry damage.
To prevent efflorescence, consider the following measures:
- Proper drainage systems, including the use of downspout extensions and gutters, can redirect water away from masonry, reducing the chances of salts being brought to the surface.
- Applying a water-repellent coating to the masonry can help minimize water absorption and efflorescence.
Note: Efflorescence should not be ignored as it may indicate a more significant water infiltration problem. Regular maintenance and prompt attention to efflorescence can prevent additional masonry damage.
Remember, addressing the root cause of efflorescence and implementing preventative measures can preserve the visual appeal and structural integrity of the building in the long run.

Frequently Asked Questions
What is the major reason of failure of masonry building?
One major reason for the failure of masonry buildings is the deterioration caused by moisture. When water seeps into the walls of masonry buildings, especially those exposed to weather conditions, it can lead to structural damage. The freezing and thawing of water within these walls further weakens the structure, exerting immense pressure that can compromise their integrity. Consequently, addressing moisture issues and implementing proper waterproofing measures are essential to prevent the failure of masonry buildings.
What are the failures in masonry?
When it comes to failures in masonry, one of the most prevalent types is horizontal shear failure. This occurs when the horizontal forces acting on the structure exceed its capacity, resulting in shearing and cracking of the masonry elements. Additionally, corner/junction failure is a common weakness in unreinforced masonry structures. The corners and junctions of these buildings are particularly vulnerable to seismic forces, and when they fail, it can lead to the collapse of the entire structure or significant damage.
What is the problem with brick masonry?
One major problem with brick masonry is its vulnerability to structural damage caused by settling walls. These settling walls can lead to step cracks, which not only compromise the integrity of the structure but also create unsightly visual blemishes. Additionally, brick masonry can suffer from vertical corner cracks, particularly during periods of prolonged drought or soil shrinkage. With the lack of moisture in such conditions, the soil surrounding and beneath the foundation contracts, leading to cracks in the corners of the masonry. Lastly, the exposure to heavy rains can result in bulging brick or masonry walls due to corrosion. As the rainwater drains down the sides of the wall, it can gradually erode the bricks and weaken the overall structure.
What are the most common modes of masonry failure explain?
One of the most common modes of masonry failure is in-plane shear failure. This occurs when the masonry units start to slide horizontally relative to each other, leading to a loss of structural integrity. In-plane shear failure can be caused by factors such as excessive lateral loads or inadequate bond strength between the masonry units.
Another common mode of masonry failure is vertical cracking. This type of failure is often caused by excessive vertical loads or inadequate reinforcement. Vertical cracks can lead to a loss of load-bearing capacity and can compromise the overall stability of the masonry structure. It is crucial to address the underlying causes and reinforce the masonry to prevent further vertical cracking.
