Keyhole Working Products enable operations to be conducted on underground gas pipes from surface level through a small ‘keyhole’ excavation. Keyhole excavation offers significant financial savings, reduced disruption to traffic and lower risk of damage to other buried plant.

The results are lower labour costs, smaller quantities of spoil and backfill material and lower reinstatement costs. Additionally, the operative is kept out of the excavation and away from the hazards associated with confined spaces
