For the penetrations with limited installation space, a mounting flange extension was used to enlarge the opening, allowing an IBMO Pressure Seal to be installed. For the corrugated conduit pipes, IBMO Hybrid Seals were selected. These seals are specifically designed for corrugated pipes and, thanks to their flexible sealing core, conform precisely to the pipe profile, creating a durable watertight and gastight seal.

Both solutions enabled the different penetration scenarios to be completed efficiently and reliably. The pipe penetrations with limited installation space, as well as the corrugated conduit pipes, now meet the required standards for watertightness, durability, and long-term operational reliability.
