Project Injection
| Singapore – Mass Rapid Transit System (MRT) | |||||
| Objective | To seal leaking joints and cracks in precast concrete tunnel segments |
| |||
| Product | MC Injekt 2300 NV, MC-Injekt 2033 | ||||
| Year | 1999 – 2001 | ||||
| Project Information | Cracks and joint leakages occurred during the construction of the Underground subway in Singapore. They were repaired to restore the durability of the tunnel. Running water was stopped by first injecting MC-Injekt 2033 and then MC-Injekt 2300 NV in order to ensure a permanent seal. MC Bauchemie / WAK Technologies was involved in seven different contracts on this project and established dual injection as the only method to ensure a long term repair | ||||
| Deep Tunnel Sewage System – T01 – T05 | ||
| Objective | TBM shield tail sealing and crack injection in concrete segment |
|
| Product | MC Injekt 2300 NV, MC-Injekt 2033, MC-Injekt GL 93 | |
| Year | 2001 - 2004 | |
| Project Information | Worn out shield tail sealing of the TBM (Tunnel Boring Machine) had to be replaced. MC-Injekt GL 93 stopped water leakages for repair of the shield tail. When the cutter head of the TBM had to be replaced, injection of MC-Injekt GL 93 created an air sealed that allowed access to the cutter head. Pre-cast concrete segments that showed cracks and water leakages after installation were injected with MC-Injekt 2033 to stop pressurised water and were then finished by sealing them with MC-Injekt 2300 NV. | |
| Changi Water Reclamation Plant – C 2 B | ||
| Objective | Crack sealing, hose injection |
|
| Product | MC Injekt 2300 NV, MC Injection Hose | |
| Year | 2003 – 2004 | |
| Project Information | The Changi Water Reclamation Plant is the largest covered sewage treatment plant in the world. Cracks in concrete structures were injected with the highly elastic MC Injekt 2300 NV – a low viscous elastomer resin that guarantees elastic and durable crack sealing | |
| Penta Ocean – Harbour Front / Vivo City | ||
| Objective | Injection of voids |
|
| Product | MC Injekt 2700 L | |
| Year | 2005 | |
| Project Information | Voids in the concrete were injected and filled with MC-Injekt 2700 L, a polyurethane with a long pot life that developed 40 N/mm2 of compressive strength, making it ideal for the strengthening of concrete structures. | |
| The Signature Pedestrian Underpass | ||
| Objective | Sealing of leaking joints |
|
| Product | MC Injekt GL 95 TR TX | |
| Year | 2005 | |
| Project Information | Leaking joints of a pedestrian underpass were successfully sealed with MC-Injekt GL 95TR TX, a polymer reinforced hydro-structure resin | |
| Singapore – Singapore Power | ||
| Objective | Sealing of leaking joints |
|
| Product | MC Injekt 2300 NV , MC Injekt 2033, MC Injekt GL 95 TX TR | |
| Year | 2006 - 2007 | |
| Project Information | Underground cable gallery at Ubi Road 3 / Ubi Ave 3 | |
| Circle Line – MRT C855 Holland Station Escape Shaft | ||
| Objective | Sealing of leaking joints |
|
| Product | MC Injekt 2300 NV , MC Injekt 2033, MC Injection Hose | |
| Year | 2007 - 2009 | |
| Project Information | Sealing of construction joints and cracks at base slab using MC Injekt 2033 to stop water pressure and MC Injekt 2300 NV to seal up the re-injectable grout tube | |
