In waterproofing projects, expansion joints, construction joints, and wall-to-floor transitions are the most vulnerable areas. Poor joint detailing leads to leaks, corrosion, and long-term structural damage. In Pakistan’s challenging weather conditions—heavy monsoon rains, intense heat, and ground movement—effective joint waterproofing is essential.

This is where Flexseal™ TPE Joint Tape from Aquafin Pakistan offers a reliable, long-term solution for critical joint sealing applications.

Flexseal™ TPE Tape


What is Flexseal™?

Flexseal is a thermoplastic elastomer (TPE)-based joint sealing tape, reinforced with polyester non-woven fabric to enhance adhesion. Designed to be embedded into waterproofing membranes like Aquafin 2K/M, it ensures a seamless, watertight seal across movement joints, construction joints, and structural connections.

Flexseal is suitable for:

  • Expansion joint waterproofing
  • Pipe penetration sealing
  • Wall-to-floor connection sealing
  • Hydraulic structure joint protection

Available in 120 mm wide rolls, with preformed corners and sleeves for complex detailing.

Why Use Flexseal for Joint Waterproofing in Pakistan?



✅ Handles Structural Movement: Over 500% elongation ensures Flexseal accommodates joint expansion and contraction without failure.

✅ Durable in Harsh Conditions: Resistant to UV, thermal changes, and mechanical stress.

✅ Watertight Protection: Bonds seamlessly into cementitious membranes, forming an integral part of your waterproofing system.

  • Water channel, drain, and reservoir joint protection

Whether you're sealing joints in a commercial project in Karachi or protecting a water infrastructure project in Lahore, Flexseal offers a versatile, high-performance solution.

How to Install Flexseal for Long-Term Waterproofing

  • Surface Preparation: Ensure joints are clean and free from dust, grease, or rust.
  • Base Membrane Application: Apply Aquafin 2K/M waterproofing membrane.
  • Embed Flexseal Tape: Press into wet membrane using a roller or trowel, ensuring continuous adhesion.
  • Overlap Joints: Overlap ends by 5–10 cm and seal with membrane.
  • Finish Coat: Apply a final membrane layer over the tape for full system integration.

For pipes and corners, use preformed accessories to simplify detailing.

Best Practices for Joint Sealing with Flexseal

  • Do not apply solvent-based products over Flexseal.
  • Protect installed tape from physical damage during construction.
  • Ensure proper overlap and sealing to prevent potential leaks.

Conclusion: Protect Your Structures with Flexseal TPE Joint Tape
