Used in all manner of construction projects throughout the world, whether for residential, commercial or industrial purposes, masonry structures are typically sturdy, durable, energy efficient, resistant to fire and even sound-proof. That said, while nothing beats masonry in terms of longevity in the construction world, it can still be prone to damage that if left unrepaired or unrestored, can pose a serious threat to the very integrity of a building or other such structure.
To help protect and preserve your masonry structure, whether it be an entire building or just a chimney, for example, it’s worth understanding what some of the biggest threats to masonry are, and how they should be dealt with.
What are classed as masonry repairs?
When a masonry contractor carries out repairs on a masonry structure, they will typically patch and plug any gaps, holes or cracks in the mortar between the stone, concrete or brickwork. In many instances, it’s necessary for the safety of a structure for the masonry professional to remove and replace any old mortar or bricks that may have become weakened over time, or due to an incident in which it became damaged.
What are 6 of the biggest threats to a masonry structure?
Below are 6 problems that can easily cause damage to any masonry structure, and which if observed, should be inspected, assessed and repaired as soon as possible:
- Moisture penetration
Moisture is hugely problematic for masonry structures, and when a masonry wall is exposed to elements such as rain, it may easily absorb it, and this typically happens either over time due to general wear and tear, or quickly due to a hole, crack or gap in the wall. Able to compromise the structural integrity of a building, water penetration will also go through the highly damaging freeze and thaw cycle, in which additional pressure is exerted onto the masonry materials used to construct the building or wall.
Rather worryingly, moisture penetration also poses a very real threat to any other materials used in the structure, such as metal, wood, windows and doors.
2. Cracks
Often found in masonry structures (particularly ones that are aged), cracks can happen when buildings settle, or in the case of water penetration as discussed above. Also, if the mortar used in the construction process wasn’t prepared properly, this can cause the joints to crack. Such natural disasters as floods and earthquakes are often responsible for cracked walls or foundations, too.
3. Staining
A problem commonly experienced by walls that face externally, staining can take place over time and as a result of continued exposure to the elements. Unsightly, most homeowners seek professional help to rectify the issue if their property starts to look stained, dirty and unkempt. Old walls and a problem with water penetration or seepage, are the main contributors to staining on masonry structures.
4. Bond failure
To ensure the stability and strength of a masonry structure, along with improve its aesthetic appearance, bricks or other building materials are arranged in a systematic manner known as the bond. However, should the adhesive material used to keep the materials in place, begin to fail, this can lead to problems such as peeling or bulging, flaking top layers or patches that are hollow.
5. Displacement
This particular structural problem takes place when steel systems used in the construction of a building begin to corrode and break down, or when there has been the use of inadequate support for the building in the form of anchors, or due to the action of the freeze/thaw cycle. When masonry materials begin to shift and move out of place, it’s commonly known as displacement.
6. Spalling
Caused by the penetration of moisture, and/or the freeze/thaw cycle over time, spalling is when the materials used to build a structure begin to fall from the masonry wall. If left untreated, spalling can have disastrous consequences for the structural stress of a masonry wall.
Protect your home or business with regular inspections from a qualified masonry contractor, and always try to have any masonry issues detected within a structure, professionally repaired in good time.
