Mortar is basically a bonding agent that makes the bricks or stones stick together firmly and strongly. Mortar joints are the fine bands that keep the stones intact and reinforce the framework. These mortar joints protect your residential and commercial properties from significant damage by repointing, but worn-out and damaged mortar joints can lead to structural vulnerabilities and weak foundations. Regular upkeep and inspections help you identify if you need repointing and masonry repairs.
In this blog, we’ll explore the red flag that contributes to damaged mortar joints, the causes of this damage, and the solutions to address this issue.
Red Flags of Deteriorating Mortar Joints
The following are the noticeable indicators of the damaged mortar joints; let’s have a look:
1. Structural Fissures in Mortar
- It occurs as the threadlike markings and microcracks on the surface.
- It shows up near corners and at structural joints.
- Most of the time, it looks like vertical separation or cracking mesh.
2. Indented Mortar Joints
- Mortar starts looking recessed below the brick surface.
- It results from environmental damage and indicates long-term deterioration.
- It makes it way easier for water to seep into the mortar joints.
When joints start receding like this, it’s often a sign that long-term weather exposure has weakened your mortar, especially in older NYC buildings.
3. Brittle & Chalky Texture Mortar
- Mortar texture becomes crumbling with friable consistency.
- It shows spalling and turns fragile to the touch.
- It lacks strong bonding performance and shows reduced structural grip.
Crumbling mortar often results from aging or poor materials. See how different types of mortar affect repointing quality and what professionals use for lasting results.
4. Bricks Coming Loose
- Mortar loses its load-bearing capacity.
- Brick displacement is noticeable.
- Bricks face shifting that leads to structural collapse.
5. Efflorescence Buildup
- White chalky stains appear on the walls.
- It happens due to residual salt formation.
- It indicates that somehow water is penetrating due to structural damage.
What Leads to Joint Failure?
Let’s have a look at the most likely causes of joint failures:
- Climatic impact: The harsh weather, like in the Bronx, and freeze-thaw cycles cause water to enter the mortar joints, which results in cracking and efflorescence.
- Defective setup: Using inappropriate mortar compounds can risk the life of the mortar joints.
- Natural aging: Premium-quality mortar can stay strong for up to 20 years, and after that, it starts to deteriorate, so repointing becomes necessary.
- Water intrusion: Insufficient water redirection and roof seepage can erode the joint stability.
These issues often show up in NYC homes due to weather and building age. If you’re dealing with similar problems, here’s how city regulations can influence your repointing options.
What action should be taken if mortar shows such signs?
Repointing is the most recommended repair strategy and efficient method to fix the damaged and failed mortar joints through masonry repairs and restoration. Repointing is the approach that consists of removing old mortar and installing the renewed joint materials. If you notice any mortar-damaging signs, you must instantly go for the repointing process.
Final Thoughts
As a final point, repointing can be a cost-effective way to revamp your masonry and fix the damage. Early detection of the signs of mortar joint damage can help prevent costly repairs. The above-given signs of the damaged mortar joints will make your property lose its resale value and give a bad impression to the interested property buyers.
