Case Study – Kier installation at Longbenton
Decisions by Kier North Tyneside enabled the construction of the Longbenton Campus in
Newcastle to get ahead of programme and introduce improvements in sustainable
practice. The design and build team managing the construction changed the design
specification of the entire floor screed installation at the campus.
Contracts Manager for Kier North Tyneside Peter Dixon was instrumental in changing the
specification from a free flowing anhydrite screed and replacing it with the well
established and leading FlexiDry F1 floor screed system.
Peter commented “Having considered the drying timelines and other performance data of
the original Anhydrite Screed System, we soon realised the floors would take 90 days to
dry which would seriously adversely impact the overall construction programme. An
alternative approach was needed.
An early decision was therefore taken by our design and build team to change the
original specification from the traditional anhydrite screed to the well established high
performance FlexiDry F1 screed system.
We took this executive decision having consulted the under floor heating and floor
screed contractors by asking them to consider the best alternative approach before
making the decision to adopt a fast 7 day dry option which would address the actual
installation timelines required on the Longbenton Campus site.
Both Warmafloor GB Ltd and CSC Screeding Ltd recommended FlexiDry F1 which we
learned also provided the added benefit of allowing light foot traffic after 12 hours
enabled better compaction properties which in turn significantly improves thermal
conductivity over and above the original anhydrite system. This subsequently enabled
our project teams and sub - contractors to better plan the installation of the Under floor
Heating System, improve the performance by the screed install teams as well as the
interior partitioning and eventually finished floor installation contractors to get ahead of
