Technobit 5 mm Unreinforced Membrane
Achieve fast, practical, and high-performance waterproofing in complex corner and joint details with Technobit 5 mm unreinforced membrane.
In construction projects, waterproofing can be technically challenging, especially in areas with three-dimensional transitions and complex details. Developed to meet these requirements, Technobit Ivar 5 mm provides maximum flexibility and adaptability thanks to its special structure without a reinforcement layer.
This single-layer application product stands out with its superior watertightness, easy installation, and high durability performance.
What is Technobit 5 mm?
Technobit Ivar 5 mm is an SBS-modified, unreinforced bituminous waterproofing membrane with PE film coating on both surfaces.
Since it does not contain a reinforcement layer, it provides excellent adaptability in difficult details such as corners, column-beam joints, and pile heads. Because it does not require additional cutting or shaping, it reduces installation time and labor costs.
Technical Specifications
Thickness: 5 mm
Reinforcement Layer: None (unreinforced structure)
Elongation Capacity: Up to 1600%
Cold Flexibility: Resistant down to -25°C
Surface Coating: PE film on top and bottom surfaces
Application Method: Torch-applied flame welding
Application Areas
- Under-foundation waterproofing applications
- Retaining wall details
- Column and beam junctions
- Pile head waterproofing
- Roof parapets and recessed areas
- Three-dimensional transition points in inverted roof systems
Application Steps
1. Surface Preparation
The concrete surface must be dry, clean, and smooth before application. Dust, loose particles, and oil residues must be completely removed.
2. Primer Application
A bitumen-based primer is applied to improve the adhesion performance of the membrane.
3. Membrane Installation
The roll membrane is positioned, and the PE film layer on the underside is heated with a torch flame to activate the bonding surface and attach it securely to the substrate.
4. Joint Areas
A minimum 10 cm overlap should be provided, and joint areas should be heat-welded to ensure complete waterproofing.
5. Protective Layer
After installation, the system can be completed by applying geotextile fabric or a protective concrete layer.
Key Advantages
Complete Adaptation to Details
Its unreinforced structure allows easy application even in the most challenging areas and complex geometries.
High Elasticity
With an elongation capacity of up to 1600%, it reduces the risk of cracking and tearing caused by structural movements.
Self-Healing Capability
In case of minor punctures, the bituminous structure can recover and help maintain waterproofing performance.
Time Saving
It reduces the need for cutting and shaping during installation.
Single-Layer Application
Thanks to its 5 mm thickness, a single-layer application is sufficient for most projects while providing high waterproofing performance.
Frequently Asked Questions
Where is Technobit Ivar 5 mm preferred?
It is safely used in critical waterproofing areas such as foundations, retaining walls, pile heads, and corner details.
What does an unreinforced membrane mean?
It means the product does not contain a reinforcement layer such as glass fiber or polyester felt. This provides a more flexible structure and allows easier application on complex details.
How does it perform in cold weather?
It maintains its flexibility down to -25°C and does not become brittle or crack.
Is a single-layer application sufficient?
Yes. Thanks to its 5 mm thickness, it provides high waterproofing performance with a single layer in most applications.
