Independently Tested by the University of Hull
In research commissioned by Flood Re and conducted at the University of Hull's PFRlab, the flexible synthetic rubber flood putty tape tested delivered the best and most consistent performance of all four adhesive tapes evaluated.
The research found that the tape:
Reduced water leakage by approximately 99% on average across six different household door types.
Outperformed conventional sandbags, which typically reduced leakage by 60–70% at higher water depths.
Performed consistently across different door designs and water depths up to 600mm.
Adapted to irregular surfaces, helping to seal difficult areas such as door frames, thresholds and corners.
The independent research, published on 15 October 2026, highlights the effectiveness of specialist flood protection tape as an accessible, temporary flood resilience solution.
