Description

Vulkem MCW Waterproofing Membrane is a high-performance, fluid-applied waterproofing solution designed to protect concrete and plywood substrates from water intrusion. This single-component, moisture-curing membrane creates a seamless, durable barrier that helps prevent structural damage caused by moisture, making it ideal for roofing systems, foundations, and high-build waterproofing applications.

Unlike traditional hot-applied systems, Vulkem MCW is cold-applied for safer, faster installation without specialized heating equipment. Its high-solids formulation ensures consistent coverage and long-term protection, even in demanding environments. It can be applied to damp or “green” concrete, helping keep projects on schedule when conditions aren’t perfect.

Perfect for contractors and professionals looking for a reliable waterproofing system, Vulkem MCW delivers flexibility, durability, and strong adhesion for long-lasting results.

Features & Benefits

  • Seamless Waterproof Protection: Creates a continuous, monolithic membrane that blocks water intrusion and protects structural integrity.
  • Easy, Cold Fluid Application: No hot kettles or melting equipment required, improving jobsite safety and efficiency.
  • Works on Damp & Green Concrete: Keeps projects moving forward in less-than-ideal conditions.
  • High Solids = Reliable Coverage: Maintains thickness during curing for dependable waterproofing performance.
  • Flexible & Crack Bridging: Expands and contracts with the substrate to prevent cracking and failure.
  • Multi-Layer Build Capability: Can be applied in multiple lifts for enhanced protection.
  • Cold Weather Adaptability: Can be water catalyzed to speed curing in lower temperatures.
  • Durable Long-Term Protection: Helps extend the life of concrete and roofing systems.
