Double Side Adhesive HDPE waterproof membrane sealing tape

HDPE tape features a robust HDPE carrier film coated on both sides with a powerful, pressure-sensitive adhesive. It is designed to form a permanent bond that withstands the harsh conditions of underground environments, including ground moisture, chemical exposure, and long-term static loads. The simple peel-and-stick application eliminates the need for heat welding or liquid adhesives, significantly reducing installation time and labor costs while ensuring a consistent and reliable seal.

Product features

      *Excellent Waterproof Sealing: Provides a fully waterproof secondary seal, effectively preventing water infiltration and protecting underground structures.*

     *Perfect Compatibility with HDPE: Specifically designed for HDPE materials, ensuring superior bond strength and long-term durability, preventing debonding due to material incompatibility.

    * Chemical and Aging Resistance: Resists degradation from common chemicals, microorganisms, and salts found in soil, offering stable performance and an extended service life.

    * Easy and Efficient Installation: The self-adhesive design requires only surface cleaning, release paper removal, alignment, and firm pressing. No need for specialized welding equipment or highly skilled labor.

    *High Bond Strength: Offers high peel and shear strength, creating a robust seam comparable to heat welding, ensuring the integrity of the lap joint.

PACKING & Logistics

Quality Control

We implement a rigorous quality control system throughout the entire manufacturing process of our waterproofing membranes， from raw material intake to finished product dispatch.

 Every batch of raw materials undergoes stringent chemical and physical property checks to ensure consistency and premium quality. During production, advanced online monitoring systems 

continuously track key parameters like thickness and uniformity. Finally, each lot of rolls is subjected to comprehensive performance tests, including tests for tensile strength, tear resistance, 

and weather resistance, to verify it meets or exceeds industry standards. This end-to-end quality assurance guarantees that every product leaving our facility is reliable and high-performing, 

providing you with complete peace of mind.
