Princes Street Edinburgh

Perfect Execution

Princes Street in Edinburgh was redeveloped into a mixed-use offering consisting of a hotel, offices and retail spaces. When constructed in 1960, the building was constructed of a concrete frame which over time has settled considerably leaving uneven flooring in some areas of the building.


Alongside the issue of uneven flooring, there were additional weight requirements as part of the renovation an additional floor was added at roof level using a steel and composite metal deck solution with Rainspan cladding, copper walls and glazing to the newly created light well and south elevation. This consequently increased the loads on the column and subsequently the foundations which have a finite capacity. 

Due to the additional weight being added to the structure, it was apparent that a conventional screed would overload the structure thus meaning a super lightweight alternative solution was required. This came in the way of Thermal Lightweight Aggregate (TLA) due to its excellent lightweight properties. With Thermal Lightweight Aggregate's self-levelling capabilities, this also ensured a solution to uneven floor issues which were being faced. 

Once laid, the Thermal Lightweight Aggregate was topped with a wearing screed to provide a suitable wearing course.

"Total Floor Solutions were great to deal with prior to installation when we were trying to identify the correct screed proposal, and professional throughout the installation, advising on suitable substrate preparation and treatment to ensure the screeding was installed timeously and efficiently, with the minimum of disruption." - Craig Dunn ISG plc
