New testing device may help to seal the deal for building owners
A building is only as secure against the environment as its most degraded joint sealants, about 50% of which fail in less than 10 years after installation. Moisture damage due to failed sealants is responsible for much of the $65 billion to $80 billion spent on annual repairs.
However, researchers at the National Institute of Standards and Technology are assembling a toolkit of measurement devices and scientific data that will help manufacturers of sealants systematically improve the protective performance of their products.
