Technobit 5 mm SBS Membrane
Technobit Technowall 5 mm SBS membrane is a high-performance waterproofing solution developed with elastomeric bitumen technology to provide superior performance, especially under low-temperature conditions. It maintains its flexibility in cold climate regions, providing reliable and long-lasting protection.
Product Description and Technical Specifications
Thickness: 5 mm
Bitumen Type: SBS (Styrene-Butadiene-Styrene) modified elastomeric bitumen
Carrier: Glass fiber
Cold Flexibility: Resistant to cracking down to -25°C
Top Surface: PE film coated
Bottom Surface: PE film coated
Roll Dimensions: Generally 10 m x 1 m
Thanks to its SBS-modified structure, Technowall 5 mm membrane maintains its elasticity even at low temperatures and does not become brittle. The glass fiber carrier provides high tensile strength and improves resistance against mechanical stresses.
Technical Advantages
Cold Weather Performance
Maintains flexibility down to -25°C and provides resistance against freeze-thaw cycles.
Elastomeric Structure
The SBS modification provides excellent crack-bridging capability and allows the membrane to adapt to surface movements.
Easy Application
It can be easily applied using a torch flame. The PE film coating on both surfaces speeds up the installation process.
Durable Reinforcement System
The glass fiber carrier increases mechanical strength and provides resistance against tearing and tension forces.
Economical Solution
Thanks to its 5 mm thickness, a single-layer application is sufficient for many projects while providing high waterproofing performance.
Application Areas
- Under-foundation and retaining wall waterproofing applications
- Waterproofing systems above parking areas
- Inverted roof systems and applications beneath protection concrete
- Pile head and detail areas
- Water tanks and pond base waterproofing
It is especially preferred in regions where freezing risks are present.
Application Steps
1. Surface Preparation
The concrete surface must be clean, dry, and smooth. Dust, loose particles, and contaminants should be completely removed.
2. Primer Application
A bitumen-based primer should be applied, and sufficient drying time should be allowed before membrane installation.
3. Membrane Installation
The roll membrane is positioned, and the bottom surface is heated with a torch flame to bond it firmly to the substrate.
4. Joint Areas
Overlap areas should be at least 10 cm, and all joints must be carefully welded to ensure waterproofing continuity.
5. Protection Layer
After installation, the membrane surface should be protected with geotextile fabric, drainage boards, or a protective concrete layer.
Advantages
Cold Resistant and Flexible: Maintains performance down to -25°C.
High Mechanical Strength: Provides a strong structure thanks to the glass fiber carrier.
Practical Installation: PE film coating enables fast and reliable application.
Long Service Life: Provides a service life of 25 years or more when correctly installed.
Frequently Asked Questions
Under which conditions is Technowall membrane preferred?
It is preferred in cold climate regions, areas exposed to freeze-thaw cycles, and applications requiring high elasticity performance.
Why is PE film coating important?
It provides fast and strong adhesion during torch application and makes the installation process easier.
Is a single-layer application sufficient?
Yes, a single 5 mm layer is sufficient for most projects. However, double-layer applications may be preferred in areas exposed to saltwater or high water pressure.
