A Complete Overview of Liquid Applied Waterproofing for Commercial Roofs

Seamless Protection and Versatility for Commercial Roofs

Liquid applied waterproofing has become an increasingly popular choice in the commercial roofing industry due to its seamless fluid membrane, strong adhesive properties, and compatibility with vertical and horizontal applications. This article will explore the benefits, application process, and important considerations for implementing liquid applied waterproofing in commercial roofing projects. By the end of this article, you will have a thorough understanding of how this innovative waterproofing method can provide the best possible moisture protection for your commercial building.

Understanding Liquid Applied Waterproofing

Liquid applied waterproofing is a cold-applied, seamless fluid membrane that forms a strong, durable, and waterproof barrier. It is suitable for both vertical and horizontal applications, providing excellent bridging capabilities for cracks and other defects. LAW is compatible with most surfaces, including concrete, masonry, and foundation walls, ensuring proper bond and the best possible moisture protection.

The Benefits of Liquid Applied Waterproofing

Seamless Fluid Membrane

The seamless fluid membrane formed by liquid applied waterproofing provides an impermeable barrier that covers the entire surface of a roof, ensuring optimal bonding and moisture protection. This continuous layer reduces the risk of water intrusion and effectively prevents damage to the underlying roof structure.

Vertical and Horizontal Applications

Liquid applied waterproofing can be applied to both vertical and horizontal surfaces, making it a versatile solution for commercial roofing projects. This flexibility allows for the effective waterproofing of foundation walls, parapets, and other challenging roof areas that may be prone to water damage.

Durable Membranes with Anti-Fracture Properties

Liquid applied waterproofing creates durable membranes that are resistant to cracking and tearing. The anti-fracture membrane reduces crack transmission and provides excellent bridging capabilities, protecting your commercial roofing system from damage caused by structural movement or thermal expansion.

Strong Adhesive Properties and Compatibility with Most Surfaces

Liquid applied waterproofing products boast strong adhesive properties, ensuring proper bond formation with a variety of substrates, including concrete, masonry, and other roofing materials. This compatibility ensures long-lasting, reliable waterproofing performance for a wide range of commercial roofing applications.

Liquid Applied Waterproofing Application Process

Surface Preparation

Before applying the liquid waterproofing product, it’s essential to inspect the final surface and address any cracks, thin spots, or other defects that may compromise the waterproofing performance. We highly recommend preparing the surface by cleaning it thoroughly and ensuring it is free from dirt, debris, and any loose or damaged materials.

Application Techniques

Liquid applied waterproofing can be applied using a brush, roller, or spray equipment, depending on the specific product and project requirements. For vertical applications, a generous coat should be applied, followed by fabric reinforcement to provide additional support and durability. In horizontal applications, multiple coats may be required to achieve the required thickness and optimal performance.

Curing Time and Environmental Considerations

The curing time for liquid applied waterproofing products may vary depending on the specific product, ambient temperature, and humidity levels. It’s important to avoid application in direct sunlight or during periods of extreme temperature fluctuations to ensure optimal bonding and moisture protection. In addition, the waterproofing membrane should be protected from water intrusion and other environmental factors during the curing process.

Factors Affecting Liquid Applied Waterproofing Performance

Substrate Compatibility

The performance of liquid applied waterproofing depends on proper bonding with the substrate. It is crucial to ensure compatibility with the surface material and follow the manufacturer’s guidelines for optimal results.

Application Conditions

Environmental factors, such as temperature and humidity, can impact the application and curing process. Avoid applying LAW in extreme temperatures or during precipitation to ensure proper bond and moisture protection.

System Thickness

Achieving the recommended system thickness is vital for the waterproofing system’s performance. Inspect the entire surface after application to ensure consistent thickness and correct any thin spots or irregularities.

Maintenance and Inspection of Liquid Applied Waterproofing

Regular Inspections

To maintain the performance and longevity of a liquid applied waterproofing system, regular inspections should be conducted to identify any potential issues, such as damage to the membrane, deterioration of the bond, or the presence of moisture.

Repair and Maintenance

If any issues are detected during an inspection, prompt repairs should be made to maintain the integrity of the waterproofing system. This may involve applying additional liquid membrane, reinforcing damaged areas, or addressing any underlying issues that may be contributing to the problem.

Liquid applied waterproofing is a versatile, durable, and effective solution for commercial roofing projects. Its seamless fluid membrane, strong adhesive properties, and compatibility with both vertical and horizontal applications make it an ideal choice for protecting commercial buildings from water damage and ensuring long-lasting performance. By understanding the benefits, application process, and maintenance requirements of liquid applied waterproofing, you can make informed decisions about the best waterproofing solution for your commercial roofing needs.
