Scottish Pier

Pier pressure for PowerPile.

An unusual use for PowerPile came up last year when the system was used to fill voiding in the eighteenth-century Aberdour Pier in Fife, Scotland.

The pier was built as a free-flowing structure which would allow a certain amount of movement, but the voiding had increased and some of the spaces needed to be filled as proactive maintenance to avert future deterioration.

“We’ve dealt with this problem in the past by using sandbags filled with weak-mix concrete, but that’s a difficult and labour-intensive solution,” explains Roy Marrian, Convener of the Aberdour Pier & Harbour Committee. “The expanding polymer is a better solution because it gets further into the holes, can be easily applied from outside, and will hopefully give a longer-lasting repair.”

Uretek completed the work in one day.

Elsewhere in Fife, Uretek resins were injected 2 metres below ground level to prevent further settlement of paving blocks at the East Pier of Anstruther Harbour, where washout of material had weakened the sub-base. Sixty square metres were treated in two days.
