Similarities in Waterproofing Solutions
The similarities in waterproofing solutions offered are specific product brands and application techniques, the core principles and types of solutions overlap significantly. Both companies leverage a combination of tried-and-true methods and modern technologies to address various waterproofing challenges.
1. Polyurethane (PU) Injection Grouting
This is a cornerstone of their waterproofing approaches. Both companies utilize PU injection grouting, or PU grouting, as a highly effective method for sealing cracks and voids within concrete structures. This technique is particularly valuable for addressing leaks originating from hairline cracks, which are often difficult to detect visually. The process involves injecting a low-viscosity polyurethane resin into the cracks under pressure. The resin expands to fill the voids, creating a durable and waterproof seal. While the specific types of polyurethane resin used might vary (depending on factors like the size of the crack and the surrounding environment), the fundamental principle remains the same: to create a long-lasting, flexible seal that prevents water penetration.
2. Waterproofing Membranes
Both companies employ various types of waterproofing membranes as part of the solution. These membranes act as barriers, preventing water from penetrating the structure. The specific type of membrane chosen depends heavily on the application area and the level of protection. For example, a flexible membrane might be suitable for areas subject to movement or expansion, while a rigid membrane could be better for flat surfaces.
The selection of the appropriate membrane is crucial and depends on several factors, including the substrate material, the expected environmental conditions (exposure to sunlight, temperature fluctuations), and the specific requirements of the project. Both possess the expertise to assess these factors and select the most suitable membrane for optimal performance.
3. Crack Repair and Sealing
Before applying membranes or performing PU grouting, both companies meticulously address visible cracks and fissures. This involves cleaning the cracks, removing any loose debris, and then applying appropriate sealants. These sealants can range from epoxy-based materials to specialized crack fillers designed to withstand water pressure and movement. The goal is to create a stable foundation for the subsequent waterproofing layers, preventing water from entering through any existing cracks.
4. Surface Preparation:
Before applying any waterproofing solution, thorough surface preparation is essential for ensuring proper adhesion and long-term performance. Both companies likely follow similar procedures, which include cleaning the surface to remove dirt, dust, oil, and other contaminants. This might involve high-pressure washing, wire brushing, or other appropriate methods depending on the substrate. Proper surface preparation is crucial to maximize the effectiveness of the waterproofing treatment and prevent premature failure.
The primary waterproofing solutions provided by both significantly overlap. Both emphasize PU injection grouting, various waterproofing membranes, and comprehensive crack repair with surface preparation to ensure durable and effective waterproofing. The difference between both are typically depends on project requirements, customer feedback, and cost considerations.
Warranties coverage on waterproofing
Both companies offer warranties on their waterproofing services, although the specific details of these warranties may vary.
1. The Importance of Warranty Information:

Leakage
The most crucial aspect of a waterproofing warranty is its coverage of leaks that occur within the warranty period. However, exclusions often apply, such as leaks caused by external factors beyond the contractor’s control (e.g., natural disasters, damage from third parties).
4. Factors Affecting Warranty Terms:
Several factors can influence the terms of a waterproofing warranty:
Type of Waterproofing
Different waterproofing methods and materials may carry different warranty periods.
Project Complexity
Larger or more complex projects may have different warranty terms than smaller, simpler ones.
Material Specifications
The specific materials used can influence the warranty duration, as manufacturers often provide their own warranties on their products.
