- Polyurethane
- Cementitious coating
- Bituminous coating or membrane
Waterproofing of tunnel is the challenging task of the tunnelling industry. Following are the methods of waterproofing used in the tunnelling,
- Waterproofing by applied spray
- Waterproofing by conventional sheets (sheets jointed by welding)
- Use of hybrid materials like waterproof concrete, admixtures mixed Portland cement and aggregate. In this case, admixtures make the concrete water-resistant.
- Use of PVC, rubber materials, Vimal PVC materials is globally accepted.
Waterproofing in the tunnel is aim to give basic support and it makes the inner structure of waterproof for the age of fast and reliable transportation without any type of hazardous situations.

Cable stayed bridges may look similar to suspension bridges. They both have roadways that hang from cables and both have towers. But the two bridges support the load of the roadways in very different ways. The difference lies in how the cables are connected to the towers . In suspension bridges, the cable ride freely across the towers, transmitting the load to the anchorages at either end. In cable stayed bridges, the cables are attached to the towers, which alone bear the load.
The cable can be attached to the roadway in a variety of ways. In a radial pattern cables extend from several points on the road to a single point at the top of the tower. In a parallel pattern, cables are attached at different heights along tower running parallel to one another.
