Novatak Sheet Membrane per Roll

Novatak Sheet Membrane per Roll

20% Recycled Butyl – Ionic Bond to Concrete – Cold, Heat, UV, and Weather Resistant.

Novatak Sheet is an adhesive-free, highly durable, non-vulcanized, 20+% reclaimed butyl rubber membrane comprised of a chemistry that creates a tenacious ionic chemical bond to poured-in-place concrete, instead of a mechanical fleece- or adhesive-concrete bond. Novatak is developed to withstand prolonged environmental exposure and follow on trades prior to the application of concrete. Novatak, unlike membranes that utilize a pressure-sensitive adhesive or non-woven fleece, creates an ionic chemical bond to concrete that is 40-75% stronger than conventional pre-applied sheet membranes. Positively charged metal oxide ions within cement react with a negatively charged active carboxyl groupings within the Novatak membrane to create an exceptionally strong ionic bond as the concrete cures.

Using Kingfield’s ionically bonding positive-side lap seam tape or double sided butyl sandwich seam tape, lateral water migration and water ingress around the building envelope is virtually eliminated by the continuously adhered membrane.

Applications

• Foundation Blindside (Single-Sided Forms)
• Pre-Applied Foundation Walls
• Pre-Applied Base Slab
• Shotcrete Structural Walls
• Horizontal Split-Slab
• Elevator Pits

Key Features

• Pre-Applied Blindside Waterproofing – Reduced excavation costs
• Fast and Easy Installation – No priming, heat welding, or challenging detailing
• Fully Adhered Seams – Laps are watertight, preventing water ingress at the seams
• Fully Adhered System – Eliminates lateral water migration behind the waterproofing membrane
• Chemically Resistant – High resistance to acids, alkalis, gases, and vapors and to most soil contaminates
• Jobsite Durability – Immediately trafficable butyl membrane is cold, heat, ponding water, puncture, and UV-resistant
• Ionic Bond to Concrete – True chemical bonding does not rely on a pressure sensitive adhesive or geo-textile mechanical bond
• Environmentally Resistant – Membrane does not require compaction or hydration, works in fresh & salt water, and will not wash out
• Foundation Wall Shotcrete Waterproofing Membrane – Utilizing Kingfield's Reinforced Seam System for blowoutprotection, Novatak completely bonds to structural shotcrete without requiring injection ports

Applications for Shortcrete Foundation Walls

Utilizing a Novatak underslab system and continuing that up the foundation walls, Novatak creates a joint-free waterproofing membrane around the entire Slab-Shotcrete Wall system. Due to Novatak’s tenacious ionic bond, strength, and the utilization of Kingfield’s Novatak Reinforced Seam System to prevent blowouts, Novatak is perfect for foundation Shotcrete applications where speed, visual performance, and waterproofing confidence are concerned. Without the need for post-application injection ports, Novatak allows for the negative surface of the Shotcrete walls to be fully exposed.
