 Duct Sealing Systems
Gas or water penetrating through underground cable or piping ducts can cause various problems varying from serious danger to substantial damage.
Filoform/ISP duct sealing systems have been developed to provide an effective and easy to install solution for gas- and watertight sealing of cable and piping in protection tubes or sleeves.
Installation
Filoform/ISP duct sealing systems are based on the application of a specially formulated expanding polyurethane sealant. Other than usual PU foams which are meant for isolation purposes only, this special sealant has a relatively limited expansion, which results in an extremely high density after full expansion, thus providing excellent mechanical strength. As a result, the sealant can resist forces applied to the cable or pipe as a result of movement of the ground.
Furthermore, the sealant shows no shrinkage after curing, and has an extremely high hydrolysis resistance.
The special polyurethane sealant is packed in a self contained two part bag, with an enclosed screw type nipple. When the sealant is dispence
Advantages
• Gas and watertight
• Can be used in any shaped or sized duct up to 200mm
• Easy and quick installation
• One complete kit for one duct seal
• Seals all known materials: PVC&PE sheeted cables, PILC cables, (HD)PE pipes, drinking water conduits
• High mechanical strength, resists ground movements, shocks and vibrations
• Also suitable for renovation works
• No architectural measures necessary
• Used by various utility companies as well as contractors
• Over 25 years of operational experience
