Ecoseal

Ecoseal is approved to Gas Industry Standard ( GIS ) Leakage Control ( LC ) 25 . It is the only product on the market to have achieved the specification set out in GIS LC25 . The specification sets out the requirements for flexible joint penetrating sealant repair systems for external application to ferrous distribution pipes with either lead / yarn or mechanical type joints . The maximum operating pressure must be equal to or less than 2 bar , in areas where pipe movement might be experienced . There are three viscosities of Ecoseal , thick , thin and ultra-thin . Each variety is designed to repair a different leaking , corroded or damaged joint . This includes mechanical , lead yarn and tightly packed joints .
Ecoseal is a two-part Polyurethane resin . This means a chemical reaction takes place when the two parts meet and combine . The process is user and environmentally friendly as no toxic fumes or chemicals are released .
Ecoseal provides an alternative to encapsulation repair systems . It is time-saving and costsaving because it eliminates the need for site assessments and measuring for encapsulation muffs . It provides an option to inject through the socket or directly through the lead joint face . Ecoseal can be used on spigots , mechanical joints , socket joints , and valves . It can be used on a range of pipes up to 2 bar pressure .
