Hydravent Venting System

A Venting Solution with Superior Compression Strength

The Hydravent Venting System acts as an absorption material beneath liners, protecting your investment and prolonging the life of your subsurface infrastructure.

When you have organic material such as dead plants or animals underground, they will produce methane gas as they decompose. Even small amounts of this gas can build up over time and create issues for your subsurface infrastructure. Methane gas buildup under a liner that is being weighed down by a body of water—or other liquids such as waste or contaminated materials—is exactly the situation where damage to your liner can occur. Hydravent prevents damage to liners by managing and venting these gases with the greatest open area of any venting system on the market.

Hydravent is strong and reliable enough that it is used not only for lagoon venting applications but also in situations such as the subway tunnels running under the city of Los Angeles. Civil engineers and site development contractors rely on the Hydravent System to provide a safe, effective solution for venting methane gas in a controlled, efficient, and safe manner.

Project Highlight

Project Name – Airport methane venting

Location – Newark, NJ

Industry / Sector – Transportation

Project Summary – Hydravent was used to vent methane gas buildup in walkway tunnel.

Product Type – Hydravent

Project Challenges – Design of venting system that would channel methane gases.

It was determined that methane gas was present in the new walkway tunnel. The specifying engineering firm out of New York City chose Hydravent to mitigate the methane from the tunnel after extensive testing on this high profile project.

As a material supplier, we worked closely with the specifying engineer to provide data and certifications. Intech Anchoring also assisted in the development of customized fittings for the specific use case on this project.

Hydravent Venting System, including the customized fittings, was chosen due to the extremely high in-flow rate of methane gases. With Hydravent’s compressive strength, the system was tested to failure and proved an excellent option for this project.

Hydravent performed as expected and continues to perform exceptionally well. The customized fittings worked as designed. Hydravent was installed with 25-foot spacing on the outside of the tunnel walls that went up and over the wall. The project was completed on time with the expected results.

Methane & Radon Gas Management

The Hydravent Venting System is made up of a fabric that allows gases to pass through and escape without the risk of clogging.

Hydravent product is designed to expel gases in order to protect your subsurface infrastructure, including pond, lagoon and landfill liner applications. 

If you’re considering the construction of a pond or lagoon, now is the time to install a venting solution to avoid a maintenance disaster.

Hydravent product lines are designed to protect the vital parts of your infrastructure, such as foundations, below-grade structures, slope and earth retention systems, brownfields, pond, lagoon, and landfill liner applications, just to name a few.

Preventing Future Damage and Costly Maintenance to Pond Liners

The Hydravent Venting System lies beneath liners and other membrane systems to help protect and preserve your investment. Liners work in tandem with systems like Hydravent to allow for the passage of gases. The passage of gas like this prevents prolonged buildup of pressure and helps to secure and extend the life of your liner. Flexible designs like this contribute to the overall longevity of your systems and your infrastructure. Making investments like this now will only save you time and money in the future.

No Hydravent product has ever failed due to a manufacturing defect, so you can have confidence and trust that Hydravent will perform for your project application. With our industry-leading quality controls in place, we stand behind our line of Hydavent products, giving it our stamp of approval. If you’re looking for one of the best ways possible to maintain the significant investment of a pond or lagoon project, reach out to Intech Anchoring today. You can take advantage of our first-rate technical support and a substantial product inventory that’s ready to meet your needs.
