When Cemplas Waterproofing and Concrete Repairs was asked by Laing O’Rourke to fix the 3,200m2 open top deck of a hospital car park in Staffordshire, the concrete maintenance services company fulfilled the task with products from Ronacrete.

To create a surface hard-wearing enough to withstand heavy vehicular traffic, while also keeping structural load to a minimum, Cemplas grit blasted the worn car park slab then reinstated it using a mix design based on a Polymer SBR modified sand and cement screed.

Based on its history of being a preferred contractor of Ronacrete, Cemplas chose to use Ronafix SBR within the mix design.

The company worked together with Laing O’Rourke and its client’s appointed engineer to decide upon a method.

Method of product application

  • 45m2 bays were created by drilling and fixing 20mm battens.
  • The cement and SBR priming coat was applied, then when tacky, laid over with the screed to create a monolithic bond.
  • A ‘tamped’ finish was created to provide grip for pedestrians, while a steel float finish was applied around the bay edges.
  • Drainage channels around the slab were laid to falls in the same way, except without incorporating the granite chips required by vehicular traffic.
