Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter
Lot 2 - Leakage SealantsMaterials used to make a full permanent repair on either metallic or PE pipe by means of either internal or external application.
Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter
Lot 3 - Bar Hole SealingA bar hole is a hole made in the soil or pavement with a hand-operated bar for the specific purpose of testing the subsurface atmosphere with a combustible gas indicator. The Materials used to plug a hole following bar hole work to provide a full permanent seal of the surface.
