Primerless waterproofing laminates.

摘要

Disclosed are methods for waterproofing civil engineering structures using flexible, sheet-like waterproofing laminates which can be applied without primer to structures at temperatures of 40 DEG F and above. Also disclosed are primerless waterproofing laminates having a bituminous layer comprising 29 to 54 weight percent asphalt, 25 to 50 weight percent process oil, and 16 to 35 weight percent thermoplastic block polymer of styrene and butadiene monomers.
