What material is used in a 60 Mil flexible polymer cement waterproofing system?

In a 60 Mil flexible polymer cement waterproofing system, polyurethane is the right material due to its excellent waterproofing properties, flexibility, and durability. Polyurethane offers a high degree of elasticity, which allows it to expand and contract with underlying structures without cracking or losing integrity. This characteristic is crucial for waterproofing applications, especially in environments that experience temperature fluctuations or structural movement.

Furthermore, polyurethane provides a robust barrier against moisture and can adhere well to various substrates, further enhancing its effectiveness in preventing water infiltration. It is also known for its resistance to chemicals, UV rays, and physical wear, making it suitable for long-term waterproofing solutions.

While other materials like rubber, cement, and bitumen serve their purposes in different contexts of construction and waterproofing, they lack the comprehensive advantages that polyurethane brings to a flexible polymer cement waterproofing system.
