The freeze-thaw cycles play a critical role in the degradation of the structural masonry, which leads to severe failures and damage to brickworks and escalates structural issues. However, proper repointing is the solution to all these problems, such as strengthening the mortars or restoring the masonry. A brick pointing can prevent your residential & commercial property from water infiltrations & freeze-thaw damages, keeping your property in one place & sturdy. But the means to repoint bricks that are badly damaged from freeze-thaw should be prompt fixing and considering the cold temperature fluctuations which go low & high.
In this blog, we’ll explore the harmful impacts, benefits, and tips to implement on freeze-thaw damage.
Understanding Freeze-uni Cycle
- The freeze-thaw cycle is the condition where the freezing temperature fluctuates from high to low, which causes bricks to repeatedly expand & contract.
- The freeze & thaw conditions promote stress on the masonry, which causes cracks & breakdown in the masonry.
How Freeze-Thaw Cycles Weaken Masonry Structure?
The following are some key points that cause severe damage to masonry & compromise the masonry structure:
1. Water Absorption & Volume Increase:
- Bricks infiltrate water easily, leading to expansion & contraction.
- The freezing mechanism exerts pressure on the bricks that causes cracks & fissures while thawing contracts the materials.
2. Mortar Joints Degradation:
- Persistent freeze-thaw actions weaken the mortar joints, causing gaps & open voids in the bricks.
- The gaps caused by freeze-thaw damage lead to opening, which enables water to seep in, accelerating future harm in harsh weather like the Bronx.
3. Cracks in Brick Surfaces:
- Bricks naturally soak up water, which lets them deteriorate easily.
- Internal water expansion can severely crack the brick surfaces, which may require brick replacements.
If you notice cracks or surface weakening, it’s also important to check whether loose or shifting bricks can be fixed with repointing.
How Does Repointing Combat Freeze-Thaw Damage?
By repointing the bricks, you can resist the freeze-thaw damage. Let’s see how repointing maintains the stability of your framework:
1. Reinforces the Structure
- It restores the worn-out mortar joints, bolstering the structure.
- It avoids additional water damage, maintaining structural stability.
2. Seals out Water Entry:
- It patches the openings formed from the freeze-thaw cycle.
- It keeps moisture out of the bricks, which lowers the risk of structural harm.
3. Increases Building Longevity:
- It increases the lifespan of the building & avoids costly fixes.
- It stabilizes the masonry and enhances the weight distribution.
Important Aspects of Repointing in Freeze-Thaw Climates
Repointing in freeze-thaw climates is a crucial process. Keep in mind to follow the following aspects when repointing:
| Aspects | Significance |
|---|---|
| Compatible Mortar Selection | Use mortar that is resilient & resists the freeze-thaw stress. |
| Appropriate Season | Mild weather can help mortars to properly cure, spring is the best season to repoint. |
| Consistent Monitoring | Helps identify damage before it becomes severe. |
Wrapping Up
In conclusion, freeze-thaw damage can be a major threat to the integrity of your building. However, repointing can be helpful in mitigating this problem. Repointing the freeze-thaw damage in your building not only fortifies the strength of your building but also enhances its appearance and avoids costly repairs.
Repointing not only prevents freeze-thaw damage but also adds value and structural strength—read why repointing a house is a smart long-term investment.

FAQs
Can you repoint my brickwork if it’s already been damaged by freeze-thaw cycles?
Yes! Sardar Restoration Corp. performs repointing on the brick that has already been damaged by the freeze-thaw cycle and installs fresh mortar that is built to last and bear the harsh winter climates of the Bronx.
Do you use special materials for buildings in cold climates?
Yes! Sardar Restoration Corp. uses special materials that bear the temperature variations without cracking the mortar of the building and stay resilient in colder climates.
How soon after winter should I schedule repointing work?
The best weather for repointing work is spring or early fall right after winter; these weather are perfect for mortar to settle, so it’s preferable to schedule repointing in such weather.
Can you help prevent freeze-thaw damage in the future?
Yes! Our repointing contractor in NYC embossed mortars that securely and tightly packed the joints so that no water can penetrate, which helps prevent freeze-thaw damage.
