A4061 Pontfrithwaun Bridges

Diamond Drilling taking place off a bridge with the sea in the background

When Bridgend Borough Council were planning to replace 2 worn out bridge decks, Skyline Rope Access was called in to take core samples through the abutments of both bridges, these had to be taken at 1000mm down from the deck and 1000mm from the bridge portal whilst working over a river.

The coring bit used was 450mm X 77mm with extension bars as the depth range could be anything up to 4000mm
