URBAN SEAL WATERPROOFING
PU Coating (Polyurethane)
Polyurethane (PU) chemical systems are the gold standard in high-performance waterproofing. They cure to form a highly elastic, seamless rubber-like membrane that bridges cracks, resists chemical attack, and stands up to UV exposure.
Advantages of Polyurethane (PU)
- Elasticity: Up to 400% elongation, protecting concrete surfaces against thermal shifts.
- Root Ingress Resistance: Ideal for planter boxes, podium gardens, and rooftop landscaping.
- UV Stability: Aliphatic PU coatings resist yellowing, cracking, or chalking under direct sunlight.
- Seamless Membrane: Continuous, joint-free application that removes weak points.
