 | | SIKA SUPPLY DURABLE CONCRETE SOLUTION FOR COASTAL WALKWAY | | | Sika Limited | | 03/07/2008 | | | A durable, high quality concrete, able to withstand the hostile marine environment was an essential requirement for the recent refurbishment and upgrading of the scenic coastal path and sea wall that links the harbour at Dundee with Broughty Ferry. A specialist mix containing Sika admixtures was supplied to the project contractors, Torith Ltd’s Civil Engineering Division, by Hanson Premix from their local Dundee plant.
Sika engineers, working closely with Hanson, designed a mix containing Sikacrete L microsilica slurry to produce a dense, extremely strong and impermeable concrete that has good resistance to chloride penetration and resistance to abrasion - all important qualities in the marine environment. Sika Ferrogard was also part of the mix to further protect the reinforcing steel from carbonation attack and Control 40 was added to reduce shrinkage of the concrete and further increase the durability.
Expansion joints along the walkway were sealed with Sikaflex-AT Construction multi-function joint sealant, part of the revolutionary new range of hybrid adhesives and sealants recently launched by Sika.
The walkway was originally built in 1923, and is often described as one of Dundee’s hidden treasures, with views across the River Tay to Fife. Apart from the work to the sea walls, the two-year, £800,000 refurbishment to the walkway has included resurfacing and replacement of rails and barriers. | |
