Sika supplied a highly crack-bridging, highly-durable car park deck system and concrete repair solution to ensure the watertight restoration of a city centre, multi-storey car park, which was carried out with minimum disruption to shoppers and nearby businesses. St Andrews MSCP, a vital facility for visitors to Norwich City Centre, required urgent repair and refurbishment. The surface of the six-storey site’s exposed top-deck had become cracked and worn since the building’s construction in 2005. To eliminate the long-term risk of water ingress and provide a safe environment for drivers and pedestrians, Norwich City Council – in conjunction with Sika recommended specialist contractors – required a replacement waterproof deck system of proven strength and long-term quality. Sikafloor®-RB58 proved ideal.
Renowned for its superb crack-bridging properties, Sikafloor®-RB58 provided the car park with a slip and abrasion-proof top deck. Fast-curing and easy to apply, the system comes with a 10-year warranty. It comprises several layers to guarantee a robust, watertight, performance. Sikafloor®-RB58 has been tested in accordance with BS EN 1062-7 for dynamic crack bridging class B 4.2; a test carried out at a temperature of -20°C, a harsher environment than even the UK winter normally provides. For the car park’s intermediate decks and ramps, Sikafloor®-RB28 was applied. The system is also known for its superb crack-bridging properties, as well as its slip and abrasion-resistance. Its fast-curing time is essential for public facility repairs where rapid refurbishment and traffic management is required to return a site to full operation as quickly as possible.
