Concrete waterproofing for commercial buildings
Waterproofing is a process that makes any object or structure waterproof or water resistant. It is typically done in multiple layers and stages to create barriers and save water from penetrating the structure of commercial buildings. This is suitable for wet environments or underwater to specific depths. Waterproofing can protect the structural content of the building from water infiltration and can cause structural damage to the concrete or corrosion to the embedded steel. However, every part of your commercial building, such as walls, roofs, and floors, should be waterproof.
Many people think that concrete waterproofing in Queens is a good choice for commercial buildings because they are long-lasting, and has multiple designs. However, if you ignore its maintenance, the lifespan of your building will become shorter. Water has become its worst enemy despite being useful in the concrete production, curing, and placement process. It wears away the outer layer and damages the integrity of the entire building structure. When concrete floors are exposed to water, the structure's durability becomes less and increases the maintenance cost. However, the toxic effects of water on concrete structures will be solved with the process of waterproofing. Concrete waterproofing uses structural or chemical treatments to make impervious barriers that prevent water or any other liquid from eroding concrete structures. There are various approaches to concrete waterproofing coating, and choosing the best procedure guarantees the safety and efficiency of the work.
Stages of Concrete Waterproofing
There are commonly two stages of concrete waterproofing, there is the construction stage and the post-construction stage.
Construction Stage
The construction stage involves the use of the right construction techniques and the right waterproofing method. For the construction stage, you need to hire a general contractor in Queens. During the construction stage, concrete should be mixed to the right water-cement ratio which will be done with the help of a professional contractor. It should also be properly compacted as water would flow through any pore in the concrete through the specific process. The concrete should be allowed to cure properly in the construction stage plumbing fittings embedded in the concrete should be properly done to prevent leakages from pipes. Concrete roofs must have the right slope. There should be no undulation in terms of construction since this allows for the free flow of water. The concrete waterproofing material should be applied very carefully according to the given instructions.
Post Construction Stage
Waterproofing should be done not only during construction but also after construction, as existing buildings might experience dampness. It appears better to waterproof concrete, especially when the building project is close to the end of the construction stage, before handing it over, to prolong the life of the waterproofing material and increase its lifespan to be as long as the building. This can also be in the form of maintenance as some waterproofing materials have different lifespans or effective life after which they begin to fail.
Methods of Concrete Waterproofing
Concrete waterproofing is a crucial aspect of the construction of commercial buildings. Maintenance of structures, preventing water infiltration and its relevant problems needs waterproofing services in NY. Concrete waterproofing helps to deal with major problems such as cracking, corrosion of reinforcing steel, and the growth of mold or mildew caused by moisture, ensuring that the concrete remains strong and resistant to water-related deterioration over time. Concrete waterproofing contractors use multiple techniques and materials to create a protective barrier against moisture infiltration. Here are some concrete waterproofing methods.
Cementitious waterproofing
The cementitious method is the easiest method of waterproofing. In this method, cement is mixed with the other bonding agents to produce a slurry that is then applied to concrete structures for waterproofing. The materials for cementitious waterproofing are easily available from suppliers of masonry products, and they are easy to mix and apply. There are two forms of cementitious waterproofing, both are non-decorative. The first consists of Portland cement which is fine aggregate. The second form of cementitious waterproofing is hydraulic cement, a compound of cement with rapid-setting non-shrinking hydraulic materials. Hydraulic cements are used for many purposes, including sealing holes, cracks, and open joints. Cementitious waterproofing is mostly used in wet areas such as toilets, dams, water treatment plants, tunnels, and river locks. Before applying this method to your concrete structure, you must ensure the area is free from dirt, laitance, and other unwanted material. Besides, there should be no holes and cracks on the surface. If available, they should be filled immediately. When mixing the products for cementitious waterproofing follow the instructions given by contractors. Cementitious waterproofing is applied in two coats. Usually, a trowel, sprayer, or brush is used during the process. This method is best suited for below-grade concrete structures.
Bituminous Waterproofing
The other way to protect or maintain your concrete structures from water is through bituminous waterproofing. Bituminous materials are made from bitumen which is a black sticky mixture of hydrocarbons used for waterproofing. The physical properties of bitumen make it an attractive option in waterproofing applications. The flexibility and protection of this method depend on the reinforcement of fiber as well as the polymer grade. The bituminous waterproofing method is mostly applied in wet areas like dams and swimming pools. However, this method is not suitable for concrete structures that are exposed to sunlight. So unless you plan on modifying it with a more flexible material like acrylic-based polymers or polyurethane, you should avoid it. Aside from bituminous coating, you can use a bituminous membrane to waterproof a concrete structure. The layers are best suited for low-sloped roofs because of their excellent performance.
Polyurethane Waterproofing
If you want to spend more on maintaining your concrete structures, then the polyurethane method is best for you. Polyurethane is made up of two components, a base (polyol) and a reactor (isocyanide). When these two components are combined, a liquid coating is formed, which is used for waterproofing. General contractors can use this method and requires minimal supervision. It installs quickly, saving time and labor costs. Besides, the method is resistant to UV rays, fuels, battery acids, and harsh climatic conditions, making it suitable for commercial buildings in Queens. Also, the waterproof solution lasts for a more extended period. It is also possible to apply this method in post-construction processes. The polyurethane waterproofing method needs extra caution while using polyurethane because it is very sensitive to moisture content. Thus, it is important to evaluate the moisture content of the concrete structure before applying the membrane to the surface. Otherwise, the layers are likely to de-bond or peel over time. Polyurethane liquid membrane waterproofing is best applicable on flat surfaces, especially on roofs that are exposed to weathering.
Conclusion
Concrete waterproofing is a major element in protecting commercial buildings in Queens from water damage. You can increase the lifespan of structures by implementing proper techniques during both the construction and post-construction stages. Hiring professional general contractors in Queens ensures that construction follows best practices, such as accurate water-cement ratios, proper compaction, and effective material application. From the easily applicable cementitious methods to advanced solutions like polyurethane waterproofing, the choice of method depends on the structure’s specific needs and environmental factors. While cementitious and bituminous approaches are ideal for areas prone to moisture, polyurethane offers versatility and durability for weather-exposed surfaces. Waterproofing not only saves the integrity of the concrete but also protects investments by preventing cracks, corrosion, and mold growth. By prioritizing routine maintenance and selecting the right waterproofing techniques, commercial buildings can remain resilient against the elements for years to come.
