Teranap Plaza Deck Waterproofing

The High Performance Solution

Madison, Wisconsin Plaza decks and green roofs add a great deal of aesthetic appeal, utility, and environmental friendliness to a building project, but they also create significant waterproofing challenges. For over 30 years, Siplast Teranap has met the needs of these demanding applications. The torch-applied, two-ply Siplast Teranap System is based on our proven roof membrane design. The elastomeric base ply, Terabase, is engineered to retain its elasticity through the rigors of deck movement. The top ply, Teranap, consists of a nonwoven polyester mat impregnated and coated with SBS-modified bitumen. The surface of the sheet is protected by a root-and puncture-resistant polyester film.

Rolls of Teranap are 2 meters wide and 20 meters long. This coverage means a significant reduction in the number of seams as compared to projects using conventional modified bitumen waterproofing products. With fewer seams, and enhanced flexibility, elasticity, and puncture resistance, the high performance Teranap Waterproofing System will stand up to the intense demands of plaza deck applications for years.

The Teranap Waterproofing System can be specified with a wide variety of surfacings for plaza deck applications, including pedestals and pavers, poured concrete, mortar and pavers, and road asphalt.
