TECHNICAL DATA
Nitra-Seal® Technical Data Sheet
Nitra-Seal is a significant improvement over older, traditional asphalt-latex membranes (ALM), providing a more chemically resistant spray-applied Nitrile-based core material. Nitra-Seal is a triple-layer system. The Nitra-Base layer (bottom) and the Land Science Bond layer (top) are composed of an HDPE material bonded to a geo-textile on the out-facing side. HDPE is known for chemical resistance, high tensile strength, excellent stress crack resistance, and highly reliable subsurface containment. The geo-textile, which is physically bonded to the chemical resistant layer, accomplishes two goals; it allows the Land Science Bond layer to adhere to the slab and provides a friction course between the Nitra-Base layer and the soil.
The Nitra-Core layer is a unique, nitrile-modified asphaltic membrane that also provides additional protection against vapor transmission1. Nitrile has been proven to offer exceptional chemical resistance in a wide range of applications. This layer creates a seal around slab penetrations and eliminates the need for mechanical fastening at termination points.
