Fv. 360 Kvistitunnelen - Osterøy PE foam
I august 2020 var WGT på Osterøy og gjorde hel innkledning av Kvistitunnelen med Pe-skum
I øvre ende av tunnel var det ikke portal etablert, så her laget WGT en løsning med oppbrett på Pe-skum slik at vann ble ledet inn i v/f sikringen.
Videre ble nedre portal dekket med Pe-skumplater på utside for å sikre mot uønsket nedfall fra fjellet.

The Bybanen at Mindemyren
NCC used Concrete Canvas (CC8) to seal a temporary dam in connection with the construction of the light rail in Bergen.
Although Concrete Canvas has a certified lifespan of over 100 years, it was chosen here because it is easy to work with, lays out quickly, and provides a strong and tight surface. You just roll it out, screw it together, and add water, and it hardens and seals within 24 hours.

Service contracts in Bergen
In the fall of 2019, Løvaas Maskin AS won a functional contract with Bergen municipality where they were to improve and maintain ditches and establish sediment traps in front of various pipes and streams. They chose to establish sediment traps using CC8, thereby making the installation simple and cost-effective.

The underground garage, Stockholm – Sweden
Rock Room Garage, Liljeholmskajen, Stockholm 47,000 sqm distributed over five rock rooms.
The project won the ROT award in 2016 and is nominated for Building of the Year 2017. A project with great complexity and volume, and with many installations, the management of leaking water was a challenge, a problem that was carefully evaluated. “The choice eventually fell on a technical solution in the form of a tunnel membrane” (Johan Ax-Riise, JM AB)
A total of 11,000 sqm of tunnel membrane has been installed, distributed across the 5 different rock rooms. In the three parking halls, the membrane was installed as a “umbrella solution” to divert leaking water from the parking areas, and in the two rock rooms that will be used as commercial areas, the membrane was installed as “full wrapping”, this to also manage moisture and create a controlled environment tailored to the intended operation.

Suction terminal – Sweden
Sweden's largest waste suction terminal. W. Giertsen Tunnel, commissioned by Veidekke Entreprenad, has installed WG Tunnel fabric in an underground facility and access tunnel intended as a waste suction terminal, located in Hjorthagen in Norra Djurgårdsstaden, Stockholm. A vault was installed, where water is led away in gutters, down into downpipes, and to existing drainage. This is to protect the installations and machinery placed in the underground facility and access tunnel.

The Tunnel Top
The Top Tunnel has always had too little driving height, and the solution was therefore a combination of WGT-100, which has a height of less than 10 cm, along with lowering the roadway. Additionally, a mesh fence was installed to avoid unnecessary vandalism on the v/F solution.

Romerike Wastewater Company and Lower Romerike Waterworks
W. Giertsen Tunnel has delivered and installed water protection solutions for NRA and NRV.
Lower Romerike Wastewater Company (NRA) is an inter-municipal wastewater company for Rælingen, Skedsmo, and Lørenskog. The facility aims to collect and treat the wastewater from the member municipalities. NRA is a mountain facility where the operational activities take place in a closed environment inside the mountain. Like all other mountain facilities, NRA also needs to control water and moisture. Lower Romerike Waterworks (NRV) is an inter-municipal company similar to NRA, but owned by Fet, Sørum, Nittedal, Lørenskog, Rælingen, and Skedsmo. The company's responsibility is to supply water to the municipalities, including also reserve water facilities. NRV is a typical mountain facility just like NRA, where production takes place in blasted halls.
W. Giertsen Tunnel was brought in as a specialist in water and frost protection for mountain halls and entered into a framework agreement with NRA/NRV in 2010. Our product WG Tunnelduk is specially developed to secure all types of mountain facilities against threatening water and dripping. In parts of the facilities, we have installed WG Tunnelduk while maintaining full operational production. NRA and NRV are now fully operational with water protection from W. Giertsen Tunnel.

Sonå Power Station
Sønnå Hydropower Plant consists of two power plants in a shared mountain hall, located at the innermost part of Saudafjorden in Rogaland. The power facilities in Saudafjorden originally began operations in 1919 and have a long tradition of power generation. In 2009, Sønnå Hydropower Plant was opened by the main owner, Elkem. The new power plant is a typical mountain facility where a total of 34 km of new tunnels have been blasted out. As with most facilities blasted out of the mountain, moisture and dripping pose a significant threat, especially in a facility like Sønnå Hydropower Plant where the mountain halls contain costly and modern equipment.
W. Giertsen Tunnel was brought in as a specialist in water protection for mountain facilities with its patented solution, WG Tunnelduk. The solution is perfectly suited for use in mountain facilities such as hydropower plants since the system is tailored to each individual project.
At Sønnå Hydropower Plant, we have delivered and installed water protection with WG Tunnelduk in the station hall, access routes, transformers, track tunnels, ventilation chambers, and cable tunnels. Sønnå Hydropower Plant is just one example of a hydroelectric facility in the mountains where W. Giertsen Tunnel has delivered water protection solutions. This is an area in which we have extensive experience, both in terms of product and technical operations.

The Light Rail in Bergen
W. Giertsen Tunnel has delivered and installed water-tightness solutions in all tunnels on the Light Rail in Bergen. The Light Rail in Bergen was realized to address the ever-increasing traffic challenges in central areas. The first part of the line opened in 2010 and has become a preferred public transport option for many travelers. W. Giertsen Tunnel with the product WGT-100 Tunnel Arch was chosen as the supplier and product for the tunnels on the light rail. The system is a complete lightweight arch and water-tightness solution.
WGT-100 requires little maintenance and very effective repairs ensure minimal downtime in case of any damage to the arch. WGT-100 from W. Giertsen Tunnel was also chosen as the tunnel arch solution for Light Rail part 2, which opened in 2013. The client was concerned that the solution should comply with applicable regulations in addition to being operationally and cost-effective. Our solution meets the requirements for use in arch tunnels. The construction of the Light Rail's last and third part started in 2013. Here too, W. Giertsen Tunnel and the WGT-100 system were chosen as the arch solution. This part runs from Lagunen to Bergen Airport, Flesland. Such a public transport offer is hoped to make the journey to and from the airport and nearby business areas much more efficient than today.
W. Giertsen Tunnel will deliver a total of around 90,000 m2 of WGT-100 distributed across all three parts of the Light Rail in Bergen. In addition, we deliver and install membranes on selected portals in the project.

Eiksund Tunnel
The world's deepest underwater road tunnel has water protection from W. Giertsen Tunnel.
The Eiksund Tunnel was opened to traffic in 2008 and is a 7,765-meter-long underwater tunnel between Hareidlandet island and the mainland. At its deepest point, the tunnel is 287 meters below sea level and has a minimum cover of approximately 50 meters. The Eiksund Tunnel is a typical Norwegian fjord crossing project – where developed communities on the outskirts are connected to more central areas.
The tunnel was constructed using the traditional "drill and blast" method, where holes are drilled and filled with explosives. W. Giertsen Tunnel AS was brought in as a subcontractor for the water and frost protection of the tunnel. The builder chose our WGT-100 solution as the most cost-effective and operationally efficient solution.
In total, we have delivered and installed over 110,000 m2 of WGT-100. The project and delivery have been a great success. Today, over 2,000 cars pass through the tunnel every single day, and the water protection solution from W. Giertsen Tunnel allows drivers to travel through a water-protected and pleasant tunnel, 287 meters below the sea.
