Cable Duct & Transit Sealing Systems (Filoform, CSD Nofirno & RISE)
Cable Duct Sealing Systems and Transit Kits provide high-performance, certified solutions for sealing underground cable ducts, boreholes, building entries, and wall penetrations against gas, water, fire, and pest ingress. Featuring industry-leading products from Filoform (including Filoseal+) and CSD Sealing Systems (NOFIRNO & RISE), these systems are engineered for both new infrastructure installations and retrospective maintenance.
Designed for long-term reliability and easy re-entry, these elastomeric and rubber sleeve/plug systems allow for straightforward network expansion and cable upgrades without compromising the seal's structural integrity or safety ratings.
Key Features & Capabilities:
Certified Gas & Water Tightness: Delivers heavy-duty protection against water pressure and hazardous gases (including Methane and Hydrogen Sulphide, $H_2S$), making them ideal for substations, manholes, and utility ducts.
Re-Enterable & Flexible: Engineered to allow easy modification and future cable pulls or replacements without requiring destructive removal or special transit frames.
Fire, Pest & Chemical Resistance: Features certified fire-rated options (EN standards / A60 class) alongside resistance to hydrocarbons, alkalis, rodents, termites, and EX-zone transitions.
Corrosion-Free & Vibration Dampening: Non-metallic components prevent internal duct corrosion, absorb mechanical vibration, and dampen acoustic transfer over service lives tested beyond 50 years.
Universal Application: Seals single, trefoil, or complex multi-cable configurations within any duct profile—bonding reliably to PVC, PE, PILC, steel, and masonry structures. Works effectively even in wet ducts when paired with running-water solutions (such as AQUASTOP).
