ABG Cavidrain Invert
ABG Cavidrain Invert is an engineered geocomposite drainage solution designed to efficiently control water flow within culverts and drainage channels.
ABG Cavidrain Invert is a high-performance geocomposite drainage solution specifically developed for tunnel invert drainage and underground infrastructure applications. Combining a durable cuspated core, it forms a controlled drainage pathway that efficiently manages water flow while reducing sediment build-up within tunnel systems.
Engineered for demanding underground conditions, it assists in reducing standing water, protecting tunnel linings, and minimising ongoing maintenance requirements. Its robust construction is resistant to abrasion and hydraulic forces, making it well suited to both new tunnel builds and rehabilitation projects.
As a prefabricated alternative to traditional drainage methods, Cavidrain Invert enables faster installation, improved site safety, and more efficient delivery on complex underground projects.
Typical applications include:
- New tunnel construction
- Cut & cover tunnels
- Drill and blast tunnels
- TBM tunnels
- Metro underground stations
- Cable tunnels
- Highway tunnels
- Railway tunnels
Frequently Asked Questions
Where is Cavidrain Invert typically used?
Cavidrain Invert is used in culverts, stormwater channels, and drainage systems where maintaining flow and preventing sediment build-up is critical.
Can it be used for culvert rehabilitation?
Yes, it is well suited for upgrading or rehabilitating existing culverts by improving hydraulic performance and reducing maintenance needs.
How does it reduce sediment build-up?
The geocomposite structure promotes efficient flow while limiting areas where sediment can settle, helping keep channels clear.
Is it suitable for high-flow environments?
Yes, Cavidrain Invert is designed to perform in demanding hydraulic conditions, with materials selected for durability and resistance to wear.
