Sika gives shoppers a safe place to park in Grimsby

Sika gives shoppers a safe place to park in Grimsby

Sika provided a fully-fleeced, waterproof flooring system to upgrade a five-storey car park in Abbey Walk, Grimsby.

The existing bituminous waterproofing membrane covering the upper deck of the failing town-centre car park had begun to de-bond from the surface, leading to surface rainwater ponding in areas.

It was decided a rapid-setting, waterproof membrane system with wearing system was required for the roof decks’ surface to preserve the building’s long-term functionality.

Clients, North East Lincolnshire County Council, in conjunction with Engie, selected Sikafloor® RB-58 Pronto, a multi-layered, robust, watertight, crack bridging system.

Work had to be carried out under challenging time constraints, contractors having to work quickly to install the system during dry weather as well as causing minimal disruption to local shoppers. Sikafloor® RB-58 Pronto’s rapid-cure properties helped them meet these time constraints.

Prior to installation, the roof deck was stripped of its existing surface. Sikafloor-RB-58 Pronto system was then applied. Firstly, Sikafloor®-11 Pronto-fast-curing primer was applied to the decks’ 2,200m2 substrate. To fully-strengthen the base coat, which also included hard wearing Sikafloor®-32 Pronto, Sika® Reemat Premium, was applied. A further layer of Sikafloor®-32 Pronto was used to encapsulate the Reemat, and once cured, Sikafloor®-32 Pronto filled with 1:2 Sikafloor® - Pronto Filler, was installed. This was followed by a proprietary Sika aggregate which added an extra layer for durability and slip resistance, as well as Sikafloor®-18 Pronto, a coloured sealing coat.

Sikafloor® RB-58 Pronto system, which also comes with a 10-year warranty, has been tested in accordance with DIN EN 1062-7 for dynamic crack bridging class B 4.2. This test is carried out at a temperature of -20°C, a harsher environment than even the UK winter normally provides.

The Sikafloor-RB-58 Pronto system ensured the Abbey Walk refurbishment was carried out with minimal disruption to the general public and nearby businesses. The building is now fully-protected against the long-term perils of water ingress to offer motorists a safe and convenient town centre parking space for many years to come.
