Introducing A New Advanced Nitrile Composite Barrier System
Nitra-Seal incorporates a nitrile-modified spray applied core and dual polyethylene sheets.
Key Benefits of Nitrile:
The dual chemical resistant layers combined with the spray-applied Nitra-Core form a barrier resistant to a wide range of chemical pollutant vapors.
Nitra-Seal is “construction friendly” as the curing time of the Nitra-Core layer and the ability to apply it in cool
er temperatures ensures quick installation and minimizes the impact on construction schedules.
Nitra-Seal forms a highly puncture resistant barrier that greatly reduces the chance of damage occurring after installation and prior to the placement of concrete.
TerraVent can be used in conjunction with Nitra-Seal to alleviate the buildup of vapors beneath structures as a result of vapor barrier implementation. Terra-Vent can be utilized as an active or passive ventilation system depending on the requirements of the design engineer.
Nitra-Seal Triple-Layer System
Dual Chemical Resistant Layers
The Nitra-Base layer (bottom) and the Land Science Bond layer (top) are composed of a 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 for 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.
Spray-Applied Nitra-Core Layer
The Nitra-Core layer is composed of a unique, nitrile-modified asphaltic membrane which 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 highly-effective seal around slab penetrations and eliminates the need for mechanical fastening at termination points.
