Uniqlo Cardiff: Ultimate K Screed Mixed on Site

1,671m² at St David's Shopping Centre. Access restrictions meant mixing Isocrete Ultimate K Screed on site in a 3-phase forced-action mixer with bulk-bag sand, delivered alongside two other Uniqlo stores at the same time.

Summary: CSC Screeding supplied and laid 1,671m² of Isocrete Ultimate K Screed for Uniqlo at St David's Shopping Centre, Cardiff. The concrete was mechanically prepared and bonded with Isocrete Polymer 70. Because of access restrictions, the screed was mixed on site in a 3-phase forced-action mixer using bulk-bag sand. Three Uniqlo stores were delivered simultaneously.

Project overview

CSC Screeding supplied and laid 1,671m² of screed for the Uniqlo store at St David's Shopping Centre, Cardiff. It was one of three Uniqlo stores we screeded simultaneously, alongside Churchill Square, Brighton and Canary Wharf, London, with each store getting the screed system that suited its site.

The challenge

A retail unit inside St David's Shopping Centre, where access restrictions shaped how the screed could be mixed and delivered. This store was also running at the same time as two other Uniqlo stores in Brighton and London.

Our solution

  • Mechanically prepared the concrete base.
  • Bonded with Isocrete Polymer 70.
  • Mixed Isocrete Ultimate K Screed on site in a 3-phase forced-action mixer, using bulk-bag sand.
  • Ran the store as one of three Uniqlo sites delivered simultaneously.
