Mapethene LT

Low-Temperature, Self-Adhered Sheet Waterproofing

Mapethene LT is a 60-mil, self-adhering sheet membrane consisting of 56 mils  of rubberized asphalt laminated to a 4-mil, cross-laminated polyethylene film.  The combination of these two excellent waterproofing materials provides a durable, high-performance waterproofing membrane. Mapethene LT membrane is suitable for installations where the ambient temperature is between 25°F and 60°F (-4°C and 16°C). When the ambient or substrate temperature is above 60°F (16°C), Mapethene HT should be used.
