A listed pier in Anstruther harbour in Scotland underwent refurbishment to repair its aging under-structure. Over 2,000 cubic meters of Sika Underwater Concrete System was used to fill the void beneath the pier without affecting its external appearance. The specially formulated concrete could be placed underwater without compaction to ensure the pier's future integrity while minimizing disruption. The project was completed on time and on budget, preserving the pier for continued public use.

SIKA UNDERWATER CONCRETE SYSTEM ENSURES FUTURE OF LISTED
SCOTTISH PIER
A listed pier in Anstruther harbour has recently undergone a major refurbishment using
the Sika Underwater Concrete System (UCS). Once the centre of the Scottish fishing in-
dustry, picturesque Anstruther harbour is now a popular tourist attraction and is mainly
occupied by private pleasure crafts. The Folly Pier in the centre of the harbour provides
primary access to the floating pontoons and is also used for parking and as a working
area for harbour users.
A structural survey by Fife Council in 1995 identified problems with the aging skeletal un-
der-structure of the pier. After further monitoring, a point was reached where repairs had
to be undertaken in order to retain the future integrity of the pier. As the pier is a listed
structure, it was essential that any repair works did not affect the external appearance of
the pier. It was also important that the repair work be long lasting and completed to a set
budget and within a short time window to minimize any disruption to users of the pier.
After a cost/benefit analysis it was decided to in-fill the void beneath the pier with mass
concrete rather than undertake repairs to the existing support framework. As the majority
of the concrete was to be placed underwater, a specially formulated mix was required that
would give very high resistance to washout and also be capable of being placed without
compaction.
The tried and tested Sika Underwater Concrete System was the solution of choice, and
Ennstone Thistle supplied 2,000 cubic metres of a special mix design formulated for this
project. The Sika Underwater System uses Sika UCS powdered underwater stabilizer to
produce a very cohesive, non-segregating mix with excellent wash-out resistance, even in
flowing conditions. This is combined with a powerful superplastisiser,Sika Viscocrete 10,
to produce a free flowing concrete mix that can be placed underwater without compaction.

PressRelease The concrete was placed within black stainless steel sheeting by three divers from under-
water engineers Atlas Marine.
Throughout the works period, the pier remained open for access to the pontoons, but car
parking on top of the pier had to be stopped. The project is now complete with no outward
appearance of the work having been carried out.
