In urgent flood situations, affordable synthetic and duct tape provide an efficient and easy-to-use alternative to sandbags for keeping water out of homes, according to tests by the University of Hull.
- Synthetic rubber tape blocks 99% of floodwater.
- Tape is cheaper, lighter, and disposable compared to sandbags.
- Outward-opening doors reduce water leakage more than inward-opening ones.
What happened
A team at the University of Hull conducted flood resistance tests using their Property Flood Resilience lab, comparing various inexpensive materials applied to doors to prevent floodwater from entering homes. Sponsored by Flood Re, a partnership between the UK government and insurers, the study focused on solutions for low-level surface water flooding, which is a rapidly growing threat affecting millions across the UK.
Their findings revealed that flexible synthetic rubber tape reduced water leakage by 99% compared to unprotected doors, while duct tape achieved a 97-98% reduction. Other types of tape also outperformed traditional sandbags, which tend to be heavy, awkward to deploy, and degrade over time. The research also highlighted that taping the outside of doors provides superior protection, and that outward-opening doors naturally lessen leakage more than inward-opening doors.
Why it feels good
This practical breakthrough offers a promising, affordable alternative for millions at risk of flooding, easing the burden of preparing homes with bulky, expensive sandbags. Tape’s ease of use and disposal makes it a much more accessible option, especially when families have little time to act during sudden weather emergencies.
The study challenges long-held beliefs about sandbags being the best quick fix for floods. Instead, it empowers people with knowledge and tools that can be stored conveniently and applied swiftly, potentially preventing significant damage and costly repairs. It also encourages homeowners to think about small, manageable steps they can take to boost their resilience ahead of flooding threats.
