Understanding Expansion Joints in Columns & Floors

Expansion joints are crucial in columns and floors to allow for natural movement due to temperature changes, seismic activities, or settling. They help prevent structural damage by accommodating these movements.

What is Expansion Joint Sealing Tape?

Expansion joint sealing tape is a specialized adhesive tape used to manage movement in expansion joints. It prevents water, air, dust, and contaminants from infiltrating the structure. Made from materials like rubber or silicone, it acts as a protective barrier, maintaining the building’s integrity and durability.

Choosing the Right Expansion Joint Tape

When selecting an expansion joint tape, it’s important to ensure compatibility with the surfaces and environment. One high-performance option is Pronil Proseal, a Thermoplastic Elastomer tape known for its flexibility, strength, and durability. It’s also safe for users and resists bacteria over the long term.

Features of Proseal Expansion Joint Tape

  • Flexible and Elastic: Adapts to movements without losing integrity.
  • Versatile: Suitable for various applications.
  • Strong Tensile Properties: Withstands stress and strain.
  • UV Resistant: Durable under sunlight exposure.
  • Heat Weldable: Easy to join with heat.
  • User-Friendly: Simple installation process.
  • Bacteria Resistant: Long-lasting cleanliness.

Benefits of Proseal Tape for Columns and Floors

For Floors (Horizontal Areas)

  • Prevents Cracks: Adapts to floor movements, reducing damage from temperature changes or settling.
  • Waterproofing: Protects floors from water damage.
  • Easy Installation: Saves time and labor costs.
  • Durable: Withstands UV rays and extreme temperatures.
  • Noise Reduction: Isolates movements and vibrations, improving living or working conditions.

For Columns (Vertical Areas)

  • Structural Integrity: Prevents cracks by accommodating natural movements.
  • Water Protection: Acts as a barrier against water infiltration.
  • Aesthetic Blending: Matches column appearance for a polished look.
  • Cost-Effective: Easy installation and minimal maintenance make it a budget-friendly choice.

Application Methods for Proseal Expansion Joint Tape

For Floors (Horizontal Areas)

  1. Surface Preparation:
    • Clean and dry the surfaces. Repair any broken edges and remove dust, oil, and contaminants.
  2. Mixing Epoxy Adhesive:
    • Mix components “A” and “B” until uniform.
  3. Application:
    • Apply adhesive to both sides of the joint.
    • Embed the tape in the adhesive, ensuring good contact.
    • Apply a second adhesive layer over the tape edges.
    • Protect the tape with a geotextile membrane or board during screeding.
    • Use a GI or Aluminum plate for protection in areas with traffic.

For Columns (Vertical Areas)

  1. Surface Preparation:
    • Follow the same cleaning steps as for floors.
  2. Mixing Epoxy Adhesive:
    • Mix components “A” and “B” until uniform.
  3. Application:
    • Apply adhesive to both sides of the joint.
    • Embed the tape in the adhesive, ensuring good contact.
    • Apply a second adhesive layer over the tape edges.
    • From ground level to 7 feet, protect with a GI or Aluminum plate.
    • Paint the tape with UV-resistant coating if needed.
