RWS-STANDARD

{ 7 September, 2015 }

Our major test program for our passive fire protection products at Efectis Nederland BV has just been completed and
from now on our SLV-External (Sprayed Limpet Vermiculite), 
in combination with our revolutionary HTA-120
BONDED fixingsystem for the armouring compound (mesh), 
has been fully certified according to the extremely
heavy RWS-Standard (Rijks Water Staat), 
which at present is the world leading standard for the internal fire protection of tunnels.

This firetests climbs up to a maximum temperature of not less than 1350°C and our SLV-External

is protecting your concrete and it’s rebars safely against the effects of fire and avoids in this way

the very dangerous spalling, which threatens the structural integrity of a tunnel in case of

a serious fire inside the tunnel.

This certification equally has offered the green light to the start of the deliveries to

the Central-to-Wanchai-Bypass Tunnel in Hong Kong, which makes us one of the absolute leaders
in the field of passive fireprotection in tunnels.
