Active Drains

Active Drains


More recent adaptions of our polyurethane closed cell foam have been used to successfully decommission chemical and active drains.

Expanding foam can be injected into drains and their connecting manholes remotely (up to 75m away) using a number of established methods. The foams are designed to give various expansion ratios from 2:1 to 20:1 to suit project requirements.

Successful projects include the decommission of a chemical drain system at Chapelcross nuclear power station and part of the active drain system at Hunterson A nuclear power station.

The National Nuclear Laboratory has carried out tests on the cured foam used in Steve Vick International’s FOAMBAG™ and associated systems and have rated it as having an 8-10 year lifespan in an area with a background radiation level of 7–9Sv.
