Technobit Proof Membrane
Technobit Proof Membrane, available in 3.5 mm and 4.5 mm thickness options, provides durable, reliable, and long-lasting waterproofing solutions, especially for foundation and retaining wall applications.
Achieving permanent waterproofing performance in buildings requires both high-quality materials and correct installation. Technobit Carisma Proof Membrane offers professional solutions for critical areas such as foundations and retaining walls thanks to its SBS-modified elastomeric bitumen structure and double reinforcement system. With its superior resistance against challenging conditions and advanced technical features, it is safely preferred in demanding construction projects.
Product Description and Technical Structure
Technobit Carisma Proof is a double-reinforced waterproofing membrane manufactured from SBS-modified elastomeric bitumen. Available in 3.5 mm and 4.5 mm thickness options, it provides solutions suitable for different project requirements.
Thanks to its combination of polyester felt and glass fiber reinforcement layers, the membrane offers high mechanical strength together with excellent flexibility.
The top surface can optionally be produced with a mineral stone coating or PE film coating depending on the application requirements.

Application Areas
Technobit Carisma Proof Membrane provides high performance in the following applications:
- Foundation and retaining wall waterproofing
- Parking structures and retaining walls
- Terrace roof waterproofing systems
- Expansion joint details
- Pile head applications
- Underground structure waterproofing systems
Especially in underground areas exposed to high water pressure, its double reinforcement structure provides superior resistance against both water and mechanical stresses.
Application Steps
1. Surface Preparation
The substrate must be clean, dry, and smooth. Dust, loose concrete particles, and surface contaminants must be completely removed.
2. Primer Application
A bitumen-based primer is applied to ensure strong adhesion between the membrane and the concrete surface. Installation should begin after the primer has fully dried.
3. Membrane Installation
The roll membrane is positioned, and the PE film layer on the underside is heated with a torch flame to bond it securely to the substrate. Care should be taken to prevent air pockets during installation.
4. Joint Areas
A minimum 10 cm overlap should be provided, and all joint areas must be properly heat-welded to create complete waterproofing continuity.
5. Protective Layer
After installation, the membrane surface can be protected with geotextile fabric, protective concrete, or suitable mechanical protection systems.
Key Advantages
Strong Double Reinforcement Structure
The combination of polyester and glass fiber reinforcement provides high tensile strength and superior resistance against tearing.
High Elasticity
The SBS-modified structure provides excellent crack-bridging capability and maintains performance even at low temperatures.
Mineral Stone Coating Option
For applications requiring UV resistance, the mineral stone surface provides additional protection against sunlight exposure.
Fast and Strong Adhesion
The PE film underside allows strong bonding to the surface through torch application.
Long Service Life
With proper installation, it can provide effective protection for 25–30 years without requiring significant maintenance.
Frequently Asked Questions
Where is Technobit Carisma Proof used?
It is safely preferred in foundations, retaining walls, terraces, and underground structures requiring waterproofing protection.
What does mineral stone coating provide?
It protects the membrane surface against UV exposure and improves resistance to sunlight.
What is the advantage of double reinforcement?
It provides high mechanical strength and increases resistance against tearing and stretching forces.
Is a single-layer application sufficient?
A single-layer application is sufficient for most projects. However, double-layer installation may be recommended in areas exposed to high water pressure.
