Our unique Filoform MD-duct sealing systems are used in both residential and commercial construction for gas and watertight sealing of underground utility cavities. We have been protecting homes and buildings for over 30 years against the ingress of gas and water through utility ducts and infrastructure. The sealing system also prevents damage or personal injury caused by flooding or a gas explosion.
MD-duct sealing systems can be made up to 2 hours fire resistant by applying our MD+ sealant.
For sealing the standard base plate in a Dutch metering room, Filoform have developed a range of sealing plugs that comply with the NEN2768.
