How relevant are the temperature curves for a given tunnel?
	Does the length of tunnel influence the protection period required?
	Does the PROMATECT® H protection inhibit the regular inspection and maintenance procedures of the tunnel, especially for water seepage and concrete spalling?
	How about reinforcment bar carbonisation? How would a PROMATECT® H lining affect the treatment of this problem in tunnels
	How are cracks in the concrete during fixing of protection material treated?
	How do we build in maintenance and service procedure for PROMATECT® after the protected tunnel is operational?
	How do we ensure the screws or bolts remain in situ ?
	How does the fixing of services and lighting to a protected concrete soffit affect the fire performance of the concrete ?
	How is the tunnel structure fire protection material installed?
	How will the protection material behave when thorough saturated from water seepage will it fall off?
	How will the protection material react to alternating pressure from vehicular traffic?
	How will the protection material react to the chemicals in the water seepage?
	Should the vertical tunnel walls be protected as well?
	What happens if after installation there are any gaps between the PROMATECT® H boards ?
	What is the experience of such repairs in other protected tunnels?
	Which is the best protection method that will minimise servicing requirements after the tunnel is completed - post cladding is easier to remove, while lost shuttering is more difficult?
