Brick repairing and installation is one of the most traditional methods of masonry. It is crucial as the strength and durability of a foundation depend on it. Though it seems like an ordinary job, it requires an expert’s hand. As a result, we have to hire the best masonry contractors in NYC to do the project with perfection.
But sometimes, we might find multiple defects in the brick masonry. It is mainly due to the negligence of the contractors. That is why brick repairs and installation in NYC need proper supervision to bypass the problems. So, before appointing any brick pointing and tuckpointing professionals in NYC, you should know the defects to avoid further complications. But what are those? Below are some of the most common defects to check for in the brick installation and repairing.
The inaccurate ratio of mortar
Most defects of brick masonry are related to the inaccurate mortar ratio. The strength of the brick and mortar are dependent upon each other. So it is imperative to mix them in a correct proportion. If not combined correctly, the strength gets decreased, and the brick becomes porous and unsafe and creates damages.
Thick and inappropriately filled bed joints
Do you know what a bed joint is? Well, it is a horizontal mortar layer, and the brick is laid upon it. So, if the layer is too thick, it will affect the strength. But why so? Well, the added thickness will produce more powerful lateral tensile forces. As a result, the brick wall might collapse as well. So, make sure that the bed joints are not too thick and filled accurately to reduce the defects. Research tells that inappropriate bed joints can diminish the brick power by 33%.
Exposing new brickwork to weather
Never expose freshly laid brickwork to extreme weather until the mortar has dried properly. In the case of extreme temperature, the heat may evaporate the moisture from the mixture. On the other hand, cold weather can displace the wall from the vertical, causing the mortar to lose strength. Therefore, you should always cover freshly laid mortar with polythene sheets. In the case of cold weather, heating the components may be necessary.
Improper suction of the bricks
The suction of the bricks is another aspect to consider. If you use dry bricks to suck the water present in the mortar, it may cause it to dehydrate. Therefore, to avoid that, you should soak the bricks in water and allow the bricks to soak them up. But always make sure that they are not extremely soaked. Soaking the bricks for 8-12 hours and removing them 1 hour before using them should be ideal.
Other defects include
- Efflorescence
- Shrinkage
- Frost Damage
Final Talk
So, that is all about the brick masonry defects. It might result from poor craftsmanship, but remember that inferior materials and weather are also responsible for the damages. That is why make sure that the contractor provides quality substances and trained professionals to do the job. Besides, check their working process and supervise the project regularly to get a more fruitful outcome.
