13. ABSTRACT (Maximum 200 words)
Sheet membrane waterproofing has been used to protect bridge decks against water and deicing salts by transpor-
tation agencies in New England for more than two decades. Though such membranes have proven useful at
extending the useful life of bridge decks, there are no convenient methods to evaluate one membrane against
another. This report details the genesis of blisters, a major problem for membranes, and defines test procedures to
evaluate sheet membranes based on their ability to adhere to concrete, accommodate strain, resist puncturing, and
pass water vapor. The results of these tests allow an engineer to compare sheet membranes based on material
properties but they, alone, cannot be used to predict how well a membrane will perform in practice. Because a
laboratory environment does not reflect the complex combination of forces and deterioration mechanisms a mem-
brane is exposed to in the field, a follow-on study of the installation/design process and long-term performance of
membranes in actual bridges needs to be conducted. This report provides a needed step toward the ability to
predict sheet membrane service life.
