The document discusses how FlexiDry floor screed has been used extensively in the Building Schools for the Future (BSF) program to renovate over 4,000 UK schools by 2029. Using FlexiDry allows for thinner screed layers and less cement usage compared to traditional screeds, saving an estimated 105,060 tonnes of cement and reducing carbon emissions by 131,325 tonnes over the course of the BSF program. FlexiDry estimates completing the screeding of 200 schools per year for the BSF project. Adopting FlexiDry specifications for the entire program could realize significant carbon emission reductions.

2. FlexiDry & BSF
FlexiDry has been used on a considerable number of
projects under the Build Schools for the Future (BSF)
programme.
Using FlexiDry allows reduced screed thickness on top
of insulation and Underfloor Heating systems and
therefore less cement is used on each project reducing
carbon emissions.

3. FlexiDry & BSF
It is estimated that over the next 20 years in
excess of 4,000 secondary schools will be built.
The project started in 2009 and currently
involves 2,367 schools.

4. FlexiDry & BSF
On average we estimate completing the screeding of
200 schools a year with the average job size per
school of 5,000 square meters.
By changing the specification of the whole BSF
project over to FlexiDry it would save 105,060 tonnes
of cement & 131,325 tonnes of CO .

8. FlexiDry & BSF
Kier converted from Anhydrite to FlexiDry Fast Drying
Screeds at Long Benton Campus, Newcastle.
Main Contractor Kier decided to change the specification after the first pour of Free
Flowing Anhydrite screed to the FlexiDry Fast Drying Screed System and used FlexiDry
F2 (14 day dry) and F3 (21 day dry) screed additives to suit the project timelines.
The reasons were their concerns as to how long the screed would take to dry before
final floor finishes could be installed, particularly heading into the winter months. The
FlexiDry Floor Screed is being installed over underfloor heating to approximately a
5,000sm area. FlexiDry provided the perfect solution and gave control back to the
Contractor.
