Waterproofing Applications

Concrete is a versatile building material known for its high durability and widespread use. However, the nature of concrete is that it is a porous material with many small voids, which means that when the surface of concrete is exposed to moisture and temperature changes over time, it can lead to a decline in quality that directly affects the structure and many related elements of your project.

Creating a waterproof coating is the best solution to maintain the integrity and extend the lifespan of structures and concrete products. Typically, waterproofing concrete is a necessary measure in conditions with high humidity and direct water exposure, such as waterproofing foundations, basements, swimming pools, and roofs.

In the modern world, there are numerous technologies and materials available for waterproofing concrete, and the choice of the most suitable type depends on various factors affecting the operation of the structure, the desired outcomes, and the available budget. Among these options, POLYCOAT stands out by offering a solution with ultra-durable Polyurea coatings that comprehensively protect concrete, ensuring both longevity and performance in diverse environmental conditions.

Concrete waterproofing solutions

As we explore the remarkable applications of Polyurea for waterproofing concrete structures, it becomes clear that this innovative material not only enhances durability but also provides essential protection against the elements, making it an ideal choice for a wide range of construction projects. One such exceptional option is the waterproofing solution using Polycoat Polyurea material, which serves as a premium coating that is exceptionally durable due to its many outstanding properties.

Waterproofing flat roofs, terraces

The rooftop is subjected to the most extreme conditions of the building, with scientific factors such as ultraviolet rays, heat, acids, and alkalis accelerating the deterioration process. Additionally, phenomena like leaks and water infiltration can cause significant damage to the building’s structural framework. The durability of the structure relies on its ability to be reliably waterproofed.

The basic steps for the application process of Polycoat Polyurea waterproofing on rooftops:

1. Surface Preparation

The application of NEWTEC PU waterproofing coating for flat roofs and terraces can be performed on a variety of existing surfaces, including concrete, mortar beds, existing tile floors, and steel substrates. All surfaces must be thoroughly prepared, cleaned, and brought to the required moisture levels according to technical specifications before commencing the application process.

2. Primer Coat

In most cases, a primer coat is necessary to enhance the adhesion between Polycoat Polyurea and the substrate. This step improves the quality of the Polyurea coating. For steel substrates, direct spraying can be done before surface treatment.

3. Polycoat Polyurea Waterproofing Layer

Proceed with the application of the Polycoat Polyurea coating to protect the rooftop substrate.

4. Finish Layer

A high UV-resistant and abrasion-resistant finish coat can be applied last when waterproofing is exposed to the elements.

Note: In Cases of Tiling or Landscaping

For the Polyurea material, a textured spray or sand application can be used during the final layer to create a rough surface for better bonding with the upper finish layer. In the case of green roofs, after waterproofing, simply apply a finishing coat in exposed areas.

Advantages

1. Highly elastic

• Polycoat Polyurea exhibits exceptional flexibility and rapid curing time (10-15 seconds), allowing it to adapt to various substrate types such as concrete, wood, and metal, regardless of shape.
• The system fully complies with standards, protecting and preserving 100% of the architecture.

2. Longevity

• Polycoat Polyurea is chemically resistant to substances like chlorine and saltwater, providing corrosion protection for structures. It is also UV-resistant and stable under high radiation, capable of withstanding significant mechanical impacts.
• It has excellent UV resistance.
• The lifespan exceeds 20 years for exposed applications and over 50 years when buried in soil or water.
• It is particularly well-suited for use as a waterproofing layer for swimming pools or water parks.

3. Fast construction time

• The rapid application capability significantly reduces downtime for maintenance and optimizes costs.

4. Safety in Use

• The Polyurea material, when applied through a mist mixing system, achieves the necessary texture.
• A slip-resistant finish option is available to ensure safety according to current regulations.

5. Aesthetic Appeal

• Color finishing options are available based on the topcoat layer.

Waterproofing foundations

The foundation is the cornerstone of any structural project, and the reliability of the entire building’s structure depends on its quality. However, the most significant factors affecting the lifespan and reliability of the foundation are the destructive impacts of moisture infiltration and temperature fluctuations. Most construction materials used in foundations, such as concrete and bricks, are porous and susceptible to water penetration. As a result, poor waterproofing quality in the foundation creates high humidity, leading to long-term mold growth that can ultimately compromise the entire structure.

The most promising waterproofing systems are polyurea and polyurethane. They possess qualities such as high adhesion, durability, and the ability to maintain their technical properties despite changes in external environmental factors. When sprayed onto any surface, polyurea forms a durable and reliable waterproof coating without seams or joints.

Renovation and waterproofing of corrugated iron roofs

In the developing industrial landscape, factories and manufacturing plants are very common and particularly crucial structures. Worldwide, most factories and plants feature prefabricated steel frame structures with large-span metal roofs. Therefore, protecting industrial plant metal roofs from corrosion and leakage is of utmost importance.

The advantages of steel-framed buildings with metal roofs are their lightweight nature, fast construction, cost-effective initial investment, and low maintenance expenses. Typically, metal roofs have a lifespan of around 20 years in natural environments. However, in coastal atmospheric conditions (with chloride content in sea air), near-shore projects, and especially in factories that emit corrosive gases such as SO2, H2S, CO2, and chlorides, the lifespan of metal roofs or steel structures is severely reduced. Metal roofs quickly corrode, leading to rust, holes, decay, leaks, or breakage within approximately 10-15 years of use, and in some cases, even earlier.

The process for treating corrosion and waterproofing metal roofs in factories includes the following steps:

1. Survey to identify the causes and assess the extent of corrosion and leakage damage to the roof.
2. Surface preparation using appropriate methods such as high-pressure washing, removing peeling coatings, and cleaning corroded areas with specialized equipment.
3. Applying high-strength, ultra-elastic PUA adhesive to seal holes, screw heads, lap joints, and expansion joints on the metal roof.
4. Using specialized spraying equipment to apply the multifunctional POLYCOAT POLYUREA (PUA) coating, ensuring complete coverage and adherence to the specified thickness across the entire roof.
5. Quality and thickness inspection of the coating using specialized ultrasonic testing equipment.
