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.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.
