Custom cast-in-place (CIP) tunnel closure products from the leading manufacturer of fabric formworks for the casting of concrete.
Sometimes a tunnel closure is required inside a dam facility or around it. Rather than using traditional methods that are difficult to install, rely on a custom-made HYDROCAST armor unit to close the tunnel.
These bags are entirely custom-made to the tunnel’s specifications and can come in different shapes such as cubes, rectangles, or shapes with curves. Unlike normal grout bags, our HYDROCAST armor units have more than two sides, making them an effective tunnel closure tool.
How is HYDROTEX used for spillway protection?
Over the lifespan of older infrastructures at power plants, dams, and municipalities, tunnels and pipelines must be closed due to evolving regulatory laws or to prevent collapse that could damage the valuable properties above.
The Solution: HYDROTEX Fabric Forms for the In-Situ Casting of Concrete
Effectively prevent catastrophic collapse by casting a custom-sized concrete bag with HYDROTEX and HYDROCAST fabric formworks. Once filled with concrete, these formworks will create a permanent bulkhead at the ends of tunnels or pipelines. In between the concrete bag bulkheads, the void space can be filled with a flowable fill or grout.

Spillway Protection for Dams
A spillway ensures that the dam doesn’t overflow or fail by allowing a controlled amount of water to spill from the dam.
To ensure that the spillway doesn’t experience a loss of soil, dam owners and engineers should factor in a need for an effective erosion control system. A concrete lining such as HYDROTEX fabric-formed concrete will ensure that the spillway continues functioning as it should.
Another solution we offer at dams is embankment protection.
