Industrial, military and hydraulic infrastructure

TechSpan® is an ideal system for all types of industrial applications. Structures can withstand impact, explosion, flood and fire. It has applications in military shelters and ammunition bunkers.

• Covered arch tunnels for underground shelters and explosive ordinance storage
• Blast protection bunkers.
• Culverts
• River crossings

TechSpan® also has applications in culvert and other water crossings. The adaptability of the arch shape allows optimisation of the section while respecting the anticipated water flow. TechSpan® is the solution of choice for these applications as the prefabricated durable concrete units used are cost-effective and construction can take place without diverting the stream.
