GEOSYNTHETICS IN TUNNELS AND UNDERGROUND WORKS

Tunnel construction, maintenance and longevity depends on optimal drainage, waterproofing, sealing, portals, erosion control and load support.

One of the most cost-effective ways to increase the useful life of a tunnel is through sealing and waterproofing. Tunnel sealing or waterproofing protects against corrosion and safeguards the structure, as well as reducing maintenance costs and repairs.

Tunnels require a drainage system to intercept and evacuate water quickly. In this way hydrostatic pressures are reduced, and water is prevented from entering the tunnel if there are weak points in the structure.

Geofabrics can provide engineering solutions and testing to reduce costs and ensure safety, while maintaining design life.

How Geofabrics can help with tunnels and underground works

• Ensure safer operations and prevent rockfalls impacting people and operations
• Efficient drainage systems to control the water pore pressure on tunnel roofs
• Provide sealing and waterproofing to protect against corrosion, deterioration and damage
• Cushioning protection and pavement stabilisation solutions
