TECHNOELAST MOST B
SBS-modified bitumen membrane TECHNOELAST MOST B 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 is a 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 polymer film.
Waterproofing material TECHNOELAST MOST B 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
