Composite Waterproofing Sheet with Enhanced Delamination Resistance

Composite Waterproofing Sheet with Honeycomb Movement-Compensating Adhesive Layer for Delamination Prevention

This technology relates to a composite waterproofing sheet with improved delamination resistance. It comprises a waterproofing sheet made of a first material, a protective waterproofing sheet made of a second material coupled to the top of the waterproofing sheet, and an elastic resin adhesive layer interposed between them to bond the two sheets together. The resin adhesive layer features multiple honeycomb-structured movement-compensating sections applied at regular intervals, connected by movement-transferring sections. By improving the application structure of the resin adhesive layer, this invention prevents delamination between the waterproofing sheet and the protective sheet, significantly enhancing durability.

Existing solutions in this field have faced structural and functional limitations that required improvement.

This technology is a composite waterproofing sheet with enhanced delamination resistance, designed to improve performance and efficiency when applied in relevant industries.
