Key Technical Advantages
Excellent Low-Temperature Performance
Technowall 5 mm remains flexible and resistant to cracking at temperatures as low as -25°C, making it ideal for regions exposed to harsh winter conditions and repeated freeze-thaw cycles.
Superior Elasticity
The SBS-modified bitumen composition provides excellent crack-bridging capabilities, allowing the membrane to accommodate structural movement without compromising waterproofing performance.
Easy Installation
The PE film coating on both sides facilitates fast and efficient torch-applied installation, ensuring strong adhesion and consistent results.
Strong Reinforcement Structure
Glass fiber reinforcement enhances tensile strength, dimensional stability, and resistance to mechanical stress, helping the membrane maintain long-term performance.
Efficient Waterproofing Thickness
With a thickness of 5 mm, the membrane often provides effective waterproofing protection in a single-layer application, reducing material and labor requirements.
Applications
Technobit Technowall 5 mm is suitable for a wide range of waterproofing applications, including:
Foundation Waterproofing
Provides reliable protection for foundations and below-grade structures.
Retaining Walls
Creates a durable barrier against groundwater infiltration and moisture penetration.
Parking Deck Waterproofing
Suitable for waterproofing systems beneath parking areas and heavy-use surfaces.
Inverted Roof Systems
Performs effectively beneath insulation and protective concrete layers in inverted roof constructions.
Pile Heads and Structural Details
Offers flexibility and adaptability for complex waterproofing details and transitions.
Water Reservoirs and Artificial Ponds
Can be used in waterproofing applications where long-term water resistance is essential.
Installation Guide
1. Surface Preparation
Before installation, the concrete substrate should be:
-
Clean
-
Dry
-
Smooth
-
Free from dust, dirt, oil, and loose particles
Proper surface preparation is essential for achieving optimal adhesion.
2. Primer Application
A bitumen-based primer should be applied to the substrate and allowed to dry completely before membrane installation begins.
3. Membrane Installation
The membrane is rolled out across the prepared surface.
Using a propane torch, the PE film on the underside is heated until the bitumen becomes activated and securely bonds to the substrate.
4. Overlap Sealing
Adjacent membrane sheets should overlap by at least 10 cm (4 inches).
All overlap joints must be carefully torch-welded to ensure a continuous waterproof barrier.
5. Protection Layer
Following installation, the waterproofing system should be protected with:
-
Geotextile protection fabrics
-
Drainage boards
-
Protective concrete screeds
This helps prevent mechanical damage during construction and throughout the service life of the system.
Main Benefits
Outstanding Flexibility in Cold Weather
Maintains flexibility without cracking or becoming brittle, even in extremely low temperatures.
High Mechanical Strength
The glass fiber reinforcement provides excellent resistance to tensile forces and mechanical impacts.
Fast and Reliable Installation
PE film surfaces allow for efficient torch application and strong bonding performance.

Frequently Asked Questions (FAQ)
1. When should Technowall 5 mm be preferred?
It is particularly recommended for cold-climate regions, areas exposed to frequent freeze-thaw cycles, and projects requiring enhanced flexibility and crack resistance.
2. What is the advantage of the PE film coating?
The PE film enables efficient torch application, promotes strong adhesion, and simplifies the installation process.
3. Is a single-layer installation sufficient?
In many standard waterproofing applications, a single 5 mm layer provides excellent protection. However, projects exposed to high hydrostatic pressure or aggressive environmental conditions may benefit from a double-layer system.
4. How does SBS-modified bitumen improve performance?
SBS modification increases elasticity, flexibility, and crack-bridging ability, helping the membrane perform effectively under structural movement and temperature changes.
5. How long does Technowall 5 mm last?
With proper installation and protection, the membrane can provide reliable waterproofing performance for 25 years or longer, depending on environmental conditions and project specifications.
