Tecbor® Boards - Tunnel Protection

In the last years, due to fire events occurred in tunnels, efficient solutions have been sought to safeguard their structural integrity.

The purpose of mercor tecresa® is to guarantee people’s safety by ensuring tunnel stability and integrity, ultimately increasing the time needed for evacuation.

Currently the EU has established within its territory the European Directive 2004/54/EC; including Spain by Royal Decree 635/2006 for tunnels, although they technically lack of established regulations. Technicians must base on the
procedures acquired in other countries, such as the NFP 502, the Dutch RWS or German ZTV among others. This last one internationally recognized.

mercor tecresa® offers solutions for tunnel protection based on the Dutch RWS, in which heating curve is described a higher temperature peak. This makes our solutions to cover the most unfavorable conditions during a fire.

Furthermore mercor tecresa®, has conducted tests in a real tunnel, adding fire power (combustible diesel) with an approximate power output of 15 Mw. These tests were conducted on the Siero tunnel (TST).

Description of Assembly

The ceiling is protected with 2 Tecbor® B 20 mm boards. First, attach 15x45x0.5 mm omega metal profiles every 610 mm, directly to concrete slab using an 8×46 mm metal anchor. Then fix the fi rst Tecbor® B 20 mm board with the 3.5×45 mm self-tapping screws. The second Tecbor® B 20 mm board is fixed with 4.2×55 mm self-tapping screws.

Walls are protected using Tecbor® B 20 mm boards anchored directly to the concrete. To fix the first board, use 8×46 mm metal anchors. For the second
board, use 8×76 mm metal anchors M6.

Apply Tecbor® joint paste to joints between boards, both in the ceiling and the walls.
