Liyana Construction NYC: Best Brick Pointing Construction Company in Brooklyn
One of the issues for which our services are most requested, as a company specializing in rehabilitation is repairing exposed brick pointing in Brooklyn. It is common on brick telling older than 20 years, the deterioration of the bricks and the brick fix that joins them. The causes of these deficiencies are very numerous, the following being the most common:
- Poor brick quality due to lack of firing or unsuitable material.
- Joint-forming mortars executed with weak or poorly proportioned cement.
- Excessive exposure to the presence of water (rain or soil) and harsh climates in winter.
- The presence of rainwater is harmful to pointing brickwork; the water during the winter season freezes, and due to its increase in volume, causes microcracking of the bricks.
For what reasons is a brick repointing repair needed?
One of the first is the passage of time: historic buildings or buildings that are already a few years old suffer the most deterioration. Pollution, rain, dust are agents that gradually deteriorate the appearance of brick pointing. We also find that much-pointing brick of buildings or private houses has plants around them. These exert a corrosive effect on the stone or cement, causing the structure to weaken. Fires are also a large part of the need for brick repointing or restoration works for new premises or homes.
In remodeling works, it can happen that workers do not take particular care with the exterior part of the brick pointing, and it suffers a blow or is damaged when the paint is spilled on it. In addition, acts of vandalism, unfortunately, continue to occur, and one of the primary victims of them is the tuckpointed brickwork of buildings and homes. One more reason for repair is that vertical gardens also fall within the brick pointing arrangement, as much as if we have had one and we want to eliminate it and maintain it.
If it is a protected brick pointing in a historic building, a common solution is an expensive replacement piece by piece. This method is usually complemented with the revision of joints. When the brick pointing is not protected and the damage is located in small areas, action can be considered piece by piece. However, this solution is not long-lasting and does not add value to the building. When it is verified that the damage is not located in one area and that the brick failure affects the entire brick pointing, the replacement solution piece by piece is meaningless because it is uneconomical.
Using varnishes and waterproofing of Brick Pointing
Film-forming coatings, such as acrylic, polyurethane, epoxy resins, etc., close the material's pores, effectively nullifying the permeability to water vapor, hinder the sweat of the cladding, and very often cause condensation and humidity interiors. It is also common for this type of treatment to yellow over time and require maintenance due to solar radiation deterioration.
On the contrary, water repellents based on organosilicon compounds have the property of covering the capillaries' walls with a skinny layer that does not clog them. This treatment is usually done by spraying an aqueous solution of silicone directly on the brick pointing. For these products to work correctly, the brick pointing must have particular characteristics and tiny marked joints. In damp soils and terrains, exterior treatment using waterproofing agents is not recommended.
How to recover a brick pointing
For any brick pointing, whether it is a private home, a block of buildings, a business block, or it is a historical monument. If we do not fix a brick pointing on time, we run the risk that the damage will increase and the costs of the repair will be even higher: a crack that ends in the collapse of a part, humidity, or the loss of a mural by the weather agents, etc. To prevent these damages as well as a deteriorating condition and neglected appearance to the building, you must act quickly.
