Technobit 5 mm: Maximum Flexibility and Waterproofing Performance for Critical Details

The Technobit Ivar 5 mm Carrier-Free Membrane is a professional waterproofing solution designed for complex construction details where flexibility, adaptability, and watertight performance are essential. It provides exceptional conformity to difficult surfaces, making it ideal for corners, joints, and three-dimensional transitions that often present challenges in waterproofing applications.

With its carrier-free structure and single-layer installation capability, Technobit 5 mm delivers efficient application, reliable protection, and long-term durability in demanding construction environments.

What Is Technobit 5 mm?

Technobit Ivar 5 mm is an SBS-modified bituminous membrane manufactured without a reinforcement carrier layer and protected with polyethylene (PE) film on both sides.

Unlike conventional reinforced membranes, its carrier-free design allows it to adapt perfectly to irregular surfaces and complex geometries, reducing the need for excessive cutting and shaping during installation.

Key Characteristics

  • SBS-modified bitumen formulation
  • Carrier-free construction
  • PE film on both top and bottom surfaces
  • Excellent flexibility and elongation
  • Designed for torch-applied installation
  • Ideal for detailed waterproofing applications

Typical Applications

Technobit 5 mm is particularly effective in areas where conventional membranes may struggle to conform properly.

Recommended Uses

  • Foundation waterproofing details
  • Retaining wall waterproofing systems
  • Column-to-beam connection zones
  • Pile head waterproofing
  • Roof parapets
  • Narrow recesses and confined spaces
  • Inverted roof transition details
  • Three-dimensional waterproofing junctions

Its flexibility makes it especially valuable in locations with multiple directional changes and complex structural elements.

Installation Process

1. Surface Preparation

The concrete substrate must be:

  • Clean
  • Dry
  • Smooth
  • Structurally sound

Dust, oil, laitance, and loose particles should be completely removed before installation.

2. Primer Application

A bitumen-based primer is applied to improve adhesion between the membrane and the substrate.

3. Membrane Installation

The membrane is rolled out across the prepared surface.

The PE film on the underside is heated using a torch until the bitumen becomes activated and bonds securely to the substrate.

4. Overlap Sealing

Adjacent membrane sheets should overlap by a minimum of 10 cm (4 inches).

The overlap areas must be fully torch-welded to create a continuous waterproof barrier.

5. Protection Layer

After installation, the waterproofing system should be protected with:

  • Geotextile protection fleece, or
  • Protective concrete screed

This safeguards the membrane from mechanical damage during subsequent construction phases.

Advantages of Technobit 5 mm

Perfect Adaptation to Complex Details

The carrier-free structure allows the membrane to conform easily to difficult shapes, corners, and structural transitions.

Exceptional Flexibility

With elongation capabilities of up to 1600%, the membrane can accommodate structural movement while minimizing the risk of cracking or tearing.

Self-Sealing Properties

The SBS-modified bitumen helps maintain waterproof integrity by naturally accommodating minor deformations and surface irregularities.

Faster Installation

Reduced cutting and shaping requirements simplify installation and help save labor time on site.

Single-Layer Efficiency

Its 5 mm thickness often eliminates the need for multiple membrane layers, reducing material usage while maintaining high waterproofing performance.

Why Choose Technobit 5 mm?

Construction details such as pile heads, structural joints, and complex transitions are among the most vulnerable points in any waterproofing system. Technobit 5 mm is specifically engineered to address these challenges by combining extreme flexibility, strong adhesion, and long-term durability in a single membrane solution.

For contractors and waterproofing professionals seeking reliable performance in demanding applications, Technobit 5 mm provides a practical and effective solution.

Frequently Asked Questions (FAQ)

1. Where is Technobit Ivar 5 mm typically used?

It is commonly used in foundation waterproofing, retaining walls, pile heads, structural joints, roof parapets, and other detail-intensive waterproofing applications.

2. What does "carrier-free membrane" mean?

A carrier-free membrane contains no reinforcement layer such as polyester felt or fiberglass. This allows the membrane to remain highly flexible and adapt easily to complex surfaces.

3. How does it perform in cold weather?

Technobit 5 mm maintains flexibility down to -25°C, helping prevent cracking and brittleness in low-temperature environments.

4. Is a single layer sufficient?

Yes. In many applications, the membrane's 5 mm thickness provides excellent waterproofing performance with a single-layer installation.

5. What makes Technobit 5 mm different from conventional membranes?

Its carrier-free structure delivers significantly greater flexibility and adaptability, making it particularly effective for complex waterproofing details where traditional reinforced membranes may be difficult to install.
