Applications
Technobit Proof Membrane is suitable for a wide range of waterproofing projects, including:
Foundation Waterproofing
Provides reliable protection against groundwater penetration and moisture infiltration.
Retaining Walls
Creates a durable waterproof barrier for below-grade wall systems.
Parking Structures
Offers resistance to water exposure and mechanical loads in underground parking facilities.
Terrace Roofs
Suitable for exposed and protected roof waterproofing systems.
Expansion Joint Details
Provides flexibility and crack-bridging performance in movement-prone areas.
Pile Heads and Stepped Surfaces
Adapts effectively to complex construction details and structural transitions.
Underground Structures
Ideal for basements, tunnels, utility structures, and other below-grade applications.
Its dual-reinforced construction makes it particularly effective in areas exposed to high hydrostatic pressure and significant structural loads.
Installation Guide
1. Surface Preparation
The substrate should be:
-
Clean
-
Dry
-
Smooth
-
Structurally stable
All dust, debris, oil, and loose materials must be removed before installation.
2. Primer Application
A bitumen-based primer should be applied to improve adhesion between the membrane and the substrate.
Installation should begin only after the primer has completely dried.
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.
Care should be taken to avoid trapped air bubbles during installation.
4. Overlap Sealing
Adjacent sheets should overlap by a minimum of 10 cm (4 inches).
All seams must be fully torch-welded to create a continuous and watertight membrane system.
5. Protection Layer
Following installation, the waterproofing system should be protected using:
-
Geotextile protection fabrics
-
Protective concrete screeds
-
Appropriate protection boards or drainage systems
This helps prevent damage during subsequent construction activities.
Key Advantages
Dual Reinforcement Strength
The combination of polyester felt and fiberglass reinforcement provides excellent:
-
Tensile strength
-
Tear resistance
-
Dimensional stability
Outstanding Flexibility
The SBS-modified elastomeric bitumen offers superior flexibility and crack-bridging capabilities, even under varying temperature conditions.
UV Protection Option
The mineral granule finish protects the membrane against ultraviolet exposure, making it suitable for exposed roofing applications.
Easy Installation
Torch-applied installation ensures a fast, reliable, and secure waterproofing process.
Long Service Life
When properly installed and protected, Technobit Proof Membrane can provide 25–30 years of waterproofing performance.

Frequently Asked Questions (FAQ)
1. Where is Technobit Carisma Proof Membrane commonly used?
It is widely used for foundation waterproofing, retaining walls, terrace roofs, underground structures, parking garages, and below-grade construction projects.
2. What is the advantage of the mineral granule finish?
The mineral-coated surface protects the membrane from UV radiation and enhances durability in exposed outdoor applications.
3. What benefits does the dual-reinforcement system provide?
The combination of polyester felt and fiberglass reinforcement improves tensile strength, tear resistance, dimensional stability, and overall durability.
4. Is a single-layer installation sufficient?
For many standard applications, a single layer is adequate. However, in areas exposed to high hydrostatic pressure or severe waterproofing requirements, a double-layer system may be recommended.
5. How long does Technobit Proof Membrane last?
When installed according to specifications and properly protected, the membrane can provide reliable waterproofing performance for 25 to 30 years or more.
