Abstract
Disclosed is waterproofing sheeting that uses a polyester layer that provides high lateral stability and puncture resistance. The waterproof sheeting can be used in many applications including waterproof roof underlayments, waterproof sheeting for foundations, underlayment for tile and flooring and various other applications. The waterproof sheeting can be manufactured without many of the problems associated with the granular coatings of existing waterproof sheeting that create excessive wear and environmental hazards.
