Cetco Cetbit 300 Membrane – 1 x 20m
Self-adhesive rubberised bitumen and HDPE waterproofing membrane for below-grade and above-grade applications. Peel-and-stick, cold-applied, and durable.
CETCO CETBIT® 300 Membrane (1m x 20m roll) is a high-performance self-adhesive waterproofing system combining 1.4mm of rubberised bitumen with a 0.1mm cross-laminated HDPE protective film. This dual-layer construction delivers exceptional adhesion, flexibility, and mechanical strength, providing a robust barrier against water ingress and structural movement.
The membrane’s factory-controlled thickness ensures consistent performance, while the cross-laminated HDPE layer offers superior tensile strength and dimensional stability. Designed for cold application, CETBIT 300 installs quickly—simply peel away the siliconised release liner and press into place without the need for torches or liquid adhesives.
Typical Applications:
- Foundation and retaining walls
- Below-grade tunnels and earth-covered structures
- Split-slab construction (above and below ground)
- Balconies, podium decks, and plaza areas
- Internal wet areas such as kitchens, bathrooms, laboratories, and mechanical rooms
Key Features & Benefits:
- Self-Adhering & Cold-Applied – No heat or additional adhesives required
- Uniform Thickness – Factory-controlled for reliable waterproofing performance
- Cross-Laminated HDPE – Resists elongation and provides exceptional durability
- High Adhesion – Rubberised bitumen bonds securely to concrete, masonry, and timber
- Fast Installation – Backed with a siliconised release liner for easy handling
- Versatile – Suitable for both structural and architectural waterproofing
Limitations:
- Not designed for permanent UV exposure—must be covered after installation
- Not a wearing surface—avoid direct foot or vehicle traffic
- Maximum in-service temperature: 40°C
