Fish-mouth-resistant waterproofing membrane

The present invention provides methods and articles for achieving puncture-resistant waterproofing membranes and for waterproofing building and civil engineering surfaces without requiring the use of separate protection boards. Exemplary membranes and methods of the invention rely on relatively thin, flexible composite layers to provide impact resistance while yet facilitating seaming between adjacent installed membranes and minimizing formation of wrinkles, leakage channels, and fish mouth openings, particularly at substrate details or other surface irregularities.
