Condition of Floors: the factory was once a lens manufacturing facility and for cleanliness, the concrete in the 4,000 sq m building had been over laid with sheet vinyl and safety flooring. The concrete underneath was in a satisfactory condition.

However, trenches left from where a previous wall had stood provided us with a difficult finishing detail. The trench that ran the length of the building was filled by the main contractor. To help avoid the occurrence of cracking through movement i.e. shrinkage causing damage to the new floor either side of the trench, the in fill required bridging using a flexible membrane. Saw cuts were made either side of the trench prior to laying the membrane. The photographs show examples of this work being carried out.

From the removal of the existing sheet vinyl floor, the preparation of the concrete, and the installation of the new floor the contract had a duration of 14 days.

Facts & Figures

  • Completion date: August 2002
  • Size of floor: 4,000 sqm
  • Product: Britdura 750

Needs

The property agent King Sturge required a floor for their client that was suitable for various types of industrial working environments and would help lift the overall presentation of the building. A primary concern of King Sturge was that our Workmanship and Materials Guarantee was transferable to the incoming tenant.

Preparation

The sheet vinyl was lifted using Turbo strippers. The preparation of the concrete was carried out using shotblasting and where the concrete had a textured surface, a combination of diamond grinding and shotblasting were used.

Floor

The Britdura 750 High Build Epoxy Floor Coating. Flexible Epoxy bridging across joints, the colour of which was matched with the floor. Reinstatement of plinths to leave a tidy finish at the foot of columns.
