Waterproofing plays an important role in protecting buildings and concrete structures from water seepage, moisture, and weather-related deterioration. However, different waterproofing systems offer different performance characteristics. Selecting the right system depends on factors such as surface condition, movement, water exposure, environmental conditions, and application requirements.
KANPROOF PU is a polyurethane-based waterproofing system designed to provide flexible and durable protection for suitable applications. Compared with some traditional rigid waterproofing approaches, polyurethane systems can offer performance characteristics such as flexibility, elongation, adhesion, and crack-bridging capability.
What Is KANPROOF PU?
KANPROOF PU is a polyurethane-based liquid-applied waterproofing system from Kangaru Polymers. It is designed to form a continuous waterproofing layer after application and curing.
Polyurethane technology is commonly used where flexibility and resistance to environmental exposure are important considerations. Depending on the product specification and application, KANPROOF PU can be used on suitable concrete and building surfaces requiring waterproof protection.
What Is Traditional Waterproofing?
Traditional waterproofing can refer to several established methods and materials used to protect structures from water ingress. Depending on the project, these may include rigid cementitious systems, conventional coatings, or other waterproofing methods.
The performance of any waterproofing system depends on the material, substrate, application method, detailing, and site conditions. Therefore, traditional waterproofing should not be considered a single technology.
The key difference is that polyurethane-based systems such as KANPROOF PU are designed to provide specific performance characteristics, particularly flexibility and elongation, which can be useful for surfaces exposed to movement.
KANPROOF PU vs Traditional Waterproofing
1. Flexibility
Building surfaces can experience movement due to temperature changes, settlement, and other factors.
KANPROOF PU is designed with flexibility that allows the waterproofing layer to accommodate certain levels of movement. This can be useful where a rigid waterproofing layer may have limitations.
2. Crack-Bridging Capability
Minor cracks can become potential paths for water ingress if they are not properly treated.
Polyurethane waterproofing systems with suitable crack-bridging properties can help maintain the continuity of the waterproofing layer across certain minor cracks and surface movements.
However, cracks should always be assessed and treated according to their type and severity before waterproofing.
3. Adhesion
Good adhesion between the waterproofing layer and substrate is important for long-term performance.
KANPROOF PU is designed to provide adhesion to suitable prepared substrates. Proper surface preparation remains essential because dust, contamination, loose material, or unsuitable substrate conditions can negatively affect adhesion.
4. Weather Resistance
Exterior surfaces such as terraces and roofs are exposed to sunlight, rain, and temperature variations.
Polyurethane waterproofing systems can provide useful weather-resistant characteristics when the selected product is suitable for the intended exposure conditions. KANPROOF PU is designed for applications where properties such as weather resistance and durability are important considerations.
5. Continuous Waterproofing Layer
As a liquid-applied system, KANPROOF PU forms a continuous coating after curing. This can help cover the surface and detailed areas such as corners and edges when correctly applied.
The continuity of the coating can be particularly useful for applications where careful detailing is required.
Where Can KANPROOF PU Be Used?
Depending on the specific product and project requirements, KANPROOF PU can be considered for applications such as:
- Terraces
- Roofs
- Podiums
- Concrete structures
- Wet areas
- Exposed surfaces
- Other suitable areas requiring flexible waterproof protection
The final product selection should always be based on the substrate, exposure conditions, and manufacturer’s technical recommendations.
Why Application Matters
The performance benefits of KANPROOF PU depend on correct application. Surface preparation, primer requirements, application thickness, curing conditions, detailing, and moisture conditions should be considered before and during installation.
A waterproofing system should not be selected only because of its material type. The complete application system and project conditions need to be evaluated.
Kangaru provides technical consultancy, specification support, and application guidance to help project teams identify and apply suitable waterproofing systems.
Frequently Asked Questions
1. What is KANPROOF PU?

Conclusion
KANPROOF PU offers a polyurethane-based approach to waterproofing where flexibility, adhesion, elongation, crack-bridging capability, and weather resistance are important considerations. Its liquid-applied nature also allows a continuous waterproofing layer to be created over suitable prepared surfaces.
Compared with some traditional rigid waterproofing approaches, polyurethane technology can provide useful flexibility and movement accommodation. However, the right waterproofing system should always be selected according to the specific structure, exposure conditions, and application requirements. With correct product selection, surface preparation, application, and technical guidance, KANPROOF PU can be a suitable option for a range of waterproofing projects.
