Sika Drainage Mat 420 is a high-performance drainage composite designed to provide exceptional protection and efficient water management for various roofing and waterproofing applications, including plaza decks, green roofs, and foundation walls. This drainage mat is part of Sika’s advanced solutions that combine durability with practical design to enhance the integrity and longevity of your construction projects.
Product Description:
Sika Drainage Mat 420 features a high-flow, dimpled polypropylene core that is heat-bonded to a non-woven polypropylene filter fabric on the top side and a protective polyethylene membrane on the bottom. This unique construction allows the mat to retain soil, sand, or other fine particles, while the filter fabric permits water to pass into the drainage core efficiently. The impermeable bottom layer serves to protect waterproofing membranes like RoofPro and Sikalastic-320 NS/SL from mechanical damage and water ingress.
Uses:
– Plaza Decks: Provides reliable water management to prevent water pooling and structural damage.
– Split Slabs and Planters: Ensures proper drainage to maintain structural integrity and prevent water-related issues.
– Ballasted and Green Roofs: Enhances roof longevity by managing excess water efficiently.
– Foundation Walls: Protects against water damage and enhances waterproofing performance.
Characteristics & Advantages:
– Multi-functional: Serves as both a protective layer for waterproofing membranes and a drainage system.
– High Compressive Strength: Suitable for areas with vehicular traffic due to its crush-resistant properties.
– Adaptability: Easily conforms to irregular surfaces, ensuring complete coverage and protection.
– Durability: Resistant to mildew, rot, and mechanical wear, making it ideal for challenging environmental conditions.
Application Instructions:
Installation of Sika Drainage Mat 420 is straightforward. Begin by cleaning the application surface from loose debris. Lay the mat directly on the Sikalastic RoofPro or Sikalastic-320 NS/SL membrane with the filter fabric side facing up. Use Sikaflex 11FC or another approved adhesive to secure the mat in place, especially at overlaps and roll ends where adjacent panels should abut closely. Ensure all joints and terminations are covered by fabric overlay to maintain the integrity of the drainage system.
Sika Drainage Mat 420 is an essential component for any construction project requiring effective moisture management solutions, delivering both protection and performance where it matters most.
