Floating – Go Further When Conditions Get Tough

Installing fiber isn’t always straightforward
Ducts can be installed under challenging conditions, with multiple bends, elevation changes, or even sections that have shifted or been compressed underground. These factors create resistance and make long-distance installations more difficult. In many projects, there is also a need to install longer sections in a single run. This is where floating technology makes a real difference.
What Is Floating?
Floating is a method where water is used instead of compressed air to transport the fiber cable through the duct. With a floating setup, the cable is carried forward by a combination of water flow and controlled pushing force from the machine. This reduces friction and allows the cable to pass through difficult sections more smoothly – even in ducts with bends, vertical movement, or tight passages.
Why Choose Jetting for Floating?
One of the key advantages of Jetting machines such as the V2, V3, and V4 Grizzon is their ability to support floating installations. By adding a Floating Kit, your machine is quickly prepared for water-assisted installation. The system is designed so that:
- The pneumatic motors are still powered by compressed air
- Water is introduced into the duct to transport the cable
- The combination ensures full control with significantly reduced resistance
This flexibility allows installers to adapt to real-world conditions without changing equipment.
Equipment Setup
To perform a floating installation, a reliable water supply is required. Jetting offers a dedicated solution with the Floating Pump, designed to deliver a stable and controlled water flow during installation. This makes the setup more flexible and easier to manage on site.
Alternatively, a water tank truck can be used to supply the necessary volume of water, depending on the project requirements and site conditions.
Teamwork in Every Floating Session
A floating installation requires coordination between two operators. One person operates the machine and controls the installation process, while the other is positioned at the far end of the duct, where the water exits. This ensures proper monitoring of the cable arrival and safe handling of the water flow. Working as a team helps maintain control throughout the entire installation and ensures a smooth and efficient process.
Reach Longer Distances
Floating is especially effective when long installation distances are required. With the right setup and conditions, fiber cables can be installed over distances exceeding 10 km (6.2 miles) between manholes in a single run. This reduces the need for additional access points and saves both time and cost on site.
After Installation
Once the cable installation is complete, the system can easily be switched back to compressed air. By reconnecting air to the duct, the remaining water can be blown out efficiently, leaving the duct ready for operation. This ensures a clean and controlled finish to the installation process.
When Conditions Demand More
Floating is not just an alternative method – it’s a powerful solution for overcoming difficult installations and maximizing efficiency. Whether you’re dealing with complex duct routes or aiming for longer installation distances, floating technology gives you the advantage needed to get the job done.
