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.

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.

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.
