Global building product manufacturer, Sika, is providing a long-term concrete repair and Total Corrosion Management (TCM) solution to strengthen the roof of the world’s oldest operating aquarium and help return it to its full, Victorian glory for generations to come.

Sikacem®-133 Gunite was selected as the high-performance, cement-based repair mortar to replenish the ageing, deteriorating concrete soffits which form part of the roof at Brighton’s historic SeaLife Centre.

Structural surveys showed a 1,200m2 area of the 174-year-old, Grade II-listed SeaLife Centre’s soffits had been subjected to prolonged chloride contamination, increasing the risk of concrete delaminating from the roof.

With the problem intensifying due to cracks forming to the limestone banding of the roof’s connecting columns, main contractors, Barwin, required a quality, large volume concrete repair solution to bolster the failing soffits and prevent further damage. Sikacem®-133 Gunite was more than up to the challenge.

Wayne Sampson, Director at main contractors, Barwin, said: “It was an honour to be selected for the refurbishment of such an esteemed Brighton landmark. The Sika concrete repair and protection system will guarantee the reinstated soffits will stand the test of time. It’s an extremely simple system to apply, as well as being incredibly effective. For such a prestigious project, a quality product was required. Sika provided it.”
