Important Features
In addition to fire protection, static-dynamic and physical aspects already listed, installed PROMATECT®-T form a protective shield which guarantees the durability of a reinforced steel construction against the penetration of chlorides, as well as salts dissolved in water.
Premature carbonation and the associated reinforcement corrosion are prevented in the long term in this manner.
Installation of Curved Boards
Lining (1) made of flexible boards or boards bent at the factory is attached directly to the structural concrete. Surface tolerances in the concrete can be compensated for, e.g. with strips of mineral wool.
Polygonal Lining
As an alternative to the design with bent boards it is possible to install a polygonal lining. This can be attached directly or – as shown in the drawing – on a substructure. Sheet steel sections can be used instead of PROMATECT®-T (2), in which case corrosion protection should be applied.
Installation on Board Strips, Watertight and Airtight Design
In constructions used as air and smoke extraction ducts in the roof section (see application example „Smoke Extraction and Ventilation Systems, Intermediate Ceiling for Smoke Extraction“) the board joints of the PROMATECT®-T board lining (1) are sealed airtight with PROMASEAL®-S (5).
This lining is therefore also impervious to water and the water from leakages is led away according to the “umbrella principle”, so that no leakage water drips into the space reserved for traffic.
