Endseals & Foamcaps
ENDSEALS™ are used to stop gas tracking back along the annular space of inserted gas mains. This method avoids spending unnecessary time and money excavating.
ENDSEALS™ are also used to avoid reinstatement ‘slump’. By sealing off the annular space, the risk of backfill gradually finding its way into the gap and causing slumping at the surface is removed.
The use of ENDSEALS™ appears in UK gas industry ‘Main Laying Procedures’ and is widely considered to be best practice.
FOAMCAP™ is a lightweight and low cost alternative to metal caps; used by the Steve Vick International Contract Services to seal off abandoned dead gas mains. They are simple to fit and may be used on uneven or badly corroded mains.
Once cured a permanent seal against the ingress of gas, water and vermin is provided.
