The white surface is UV-stable, and is ideal for waterproofing tunnels and spaces with poor visibility and high temperatures.<\/p>\n

The white surface accumulates less heat than a black surface, with a difference between the two of between 20 and 23\u00ba C. As a result, it is possible to work for longer periods, and the number of geomembrane waves or wrinkles is reduced.[\/vc_column_text][vc_column_text]<\/p>\n

Characteristics and advantages <\/i><\/h2>\n

[\/vc_column_text][vc_column_text]<\/p>\n

<\/i> Greater visibility in closed spaces (tunnels and water tanks)<\/p>\n
