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 dispenced, there is no possibility of exposure to operatives.
