Dynamic development of road infrastructure, ecological and urban aspects make it necessary to build more and more tunnels. However, this involves the risk of accidents, often tragic in consequences. It comes to them mainly due to the specificity of these buildings. The events that occurred in tunnels for many years and in various locations show how important the fire protection function of the structure and the fact that one should not underestimate the threats that may arise during even the smallest fire.
Fireproof linings – where are they used?
One of the fire protection measures is the use of appropriate lining of fire-resistant tunnel constructions. They are aimed at preventing the formation of thermal spalling of concrete, as well as protecting concrete against the penetration of gases from the combustion of materials. In turn during normal operation they protect against dirt and moisture. These protections extend the lifetime of the structure of the object.
Why is fire resistant cladding used in the infrastructure?
GRC glass fiber reinforced concrete can be used in the majority of various construction projects. Its indisputable advantages such as: high resistance to temperature changes and high fire resistance, as well as excellent material strength for all types of corrosion, as well as all forms of aggressive environment, make it used in various fields. It is used, among others, in such difficult conditions as façade claddings of bridges, as well as claddings of road tunnels, railway tracks and tunnels.
The special lightness and high plasticity of this raw material makes it often used for the assembly of façade cladding, road, spatial and railway claddings as well as diaphragm wall linings. Thanks to the unique characteristics of GRC concrete, refractory linings of this type are also extremely light, which greatly facilitates their transport and assembly. An additional advantage is their versatility, repeatability of motifs and invoices, which means that their installation does not require a long planning process. Even with quick folding, we get a smooth surface with a uniform pattern.
