Pre-applied, ionic bonding waterproofing sheet system
Novatak Sheet is a highly durable non-vulcanized reclaimed butyl rubber membrane comprised of a chemistry that creates a tenacious ionic chemical bond to cast in place concrete. Novatak is specially developed to withstand prolonged environmental exposure prior to concreting.
Unlike conventional membranes that utilize a pressure sensitive adhesive, Novatak creates an ionic chemical bond that is many times stronger than many traditional pre-applied sheet membranes. Positively charged metal oxide ions in cement react with a negatively charged active carboxyl group (-COOH) in Novatak to create an exceptionally strong ionic bond. Lateral water migration and water ingress is prevented through a continuously adhered membrane around the building envelope.

NOVATAK WATERPROOFING SYSTEM
Fully adhered ionic bond to concrete eliminates lateral water migration behind the membrane. Does not rely on a pressure sensitive adhesive.
Non-vulcanized butyl rubber has excellent durability characteristics, chemical resistance, puncture and tear resistance.
Jobsite durability reduces potential damage to the membrane prior to the concrete pour, UV, heat and cold resistant. Rain? No problem.
Novatak Sheet is comprised of reclaimed rubber, over 20% recycled content.
Fast and easy installation, no priming, heat welding or challenging detailing.
Fully adhered seams. Laps are watertight preventing water ingress at the membrane sheet seams.
No bentonite or environmentally reactive materials prevents preactivation.
