TECHNOELAST MOST B GREY SLATE

SBS-MODIFIED BITUMEN WATERPROOFING MEMBRANE FOR BRIDGE AND FLYOVER CONSTRUCTION

SBS-modified bitumen membrane TECHNOELAST MOST B grey slate is designed for waterproofing of reinforced concrete slab of carriageway on bridge constructions and other traffic areas. It can be also used as a single-layer waterproofing of the foundation.

TECHNOELAST MOST B grey slate is the waterproofing material produced by two-sided placing of a high-quality polymer-bitumen binder on a polyester base. The material has additional durability and resistibility features thanks to special formula of polymer-bitumen binder and increased thickness.

On the bottom side the material is covered by a polymer film with special graphic elements, melting of which indicates the proper material heating. On the top side the material is covered by a coarse-grained slate that protects the material from direct sunlight during installation. The membrane can be laid loosely in underground structures.

Waterproofing material TECHNOELAST MOST B grey slate has the following advantages:

  • High puncture resistance and resistance to foot marking
  • High quality polyester reinforcement
  • An additional durability and resistibility features thanks to the special formula of polymer-bitumen binder and increased thickness
