Description of material

Tunnel unreinforced two-layer waterproofing membrane based on high-quality plasticized polyvinylchloride (PVC) with a bright-yellow signal layer. It is used for waterproofing bridgeworks, tunnels, basements of buildings and structures. The length of a membrane roll can be chosen by request. LOGICROOF T-SL is not stabilized against permanent exposure to UV-radiation.

Appearance: The surface is smooth, with TechnoNICOL logo; the top layer is an alarm, bright yellow; the bottom layer is black.

Method of application

LOGICROOF T-SL PVC-membrane should be welded using hot air produced by automatic welding equipment Contact with all materials containing bitumen or solvents should be avoided. Direct contact with polymeric materials made of polystyrene (EPS, XPS) is not allowed.

Temperature limitations for installation:
– Base temperature: min -25°C/max +50°C
– Air temperature: min -15°C/max +50°C


Rolls should be stored horizontally on pallets in their original packing, in a place protected from direct sunlight, rain and snow. Storage in two stages with use of rigid spacers is allowed. When observing storage condition limitations the service life is unlimited.
