Bitumen membrane Technoelast K-MS 170/3000

Bitumen membrane Technoelast K-MS 170/3000 is a premium class polyester based Underlay, saturated and coated with high quality SBS modified bitumen. The membrane is finished with fine-grained sand on both sides. Material can be used as underlays in built up waterproofing systems or as vapour barriers on new built or refurbished flat roofs as well as part of overlay systems to existing asphalt waterproofing. Not recommended for use as single ply waterproofing.

Bitumen membrane Technoelast K-MS 170/3000 is applied by traditional Pour and Roll  method onto previously prepared surface, clear of any debris or sharp projections. Primers shall be used to prepare substrate for achieving most effective waterproofing longevity.

Side laps must be minimum 75mm with end laps at minimum of 100 mm. The subsequent cap sheet layer should be offset 300 mm from the underlay to avoid build up of overlaps.
