Sealing between pipes and walls

In water, sewer, and process systems managed by public bodies and industrial operators, the point where pipes meet the building structure is one of the most frequently underestimated critical points during the design phase. EURONOVA offers a range of systems designed to meet different operational needs.

Features and benefits

An improperly sealed penetration exposes the infrastructure to water infiltration, gas ingress, vibration transmission and, in seismic zones, the risk of failure due to differential settlement.

The consequences, in terms of service restoration and interruption costs, are often disproportionate to the cost of the preventive solution.

Each product is selected and qualified to ensure compliance with reference standards and compatibility with the main piping materials in use: steel, cast iron, copper, PVC, polyethylene and PEX.

The advantages shared by the range of solutions for sealing pipes and walls include ease of installation, durability, and dimensional versatility, with diameter ranges covering everything from small users to the large-diameter pipes typical of primary distribution networks.

Wall Passage Joint – GP

The GP Series is EURONOVA's system for sealing annular spaces in wall penetrations for smooth pipes made of PVC, HDPE, steel, and other materials. The flexible chain structure of modular elements adapts to any diameter, from DN 50 mm to DN 3000 mm, precisely covering both large distribution pipes and service passages.

The system is available in three material variants to meet different system needs: Standard, Hydrocarbons and Potable.

Wall Collars - Closed or Open

The CLC and CLA Series collars guarantee mechanical sealing of wall penetrations for gas, water, and cable ducts, on holes from 50 mm to 400 mm. The high-quality EPDM rubber sealing body ensures long-lasting resistance to aging, atmospheric agents, and temperature variations from -30°C to +120°C. Circular flanges and AISI 304 stainless steel bolts complete the system, with certified operating pressures of up to 3 bar.

They are available in two variants intended for different contexts of use:

  • CLC Series — closed: for new installations. It is inserted into the duct before being permanently positioned in the wall;
  • CLA Series — Open: for work on existing networks. The openable structure allows the pipe to be gripped directly inside the hole, without disconnecting or interrupting the pipeline.

Simple Wall Collars – PIPPO

The PIPPO collar is the sealing element for the hydraulic waterproofing of penetrations in concrete structures (such as walls, manholes, swimming pools and slabs) where the risk of infiltration along the external surface of the pipe is higher.

They can be installed on any smooth pipe (PVC, PE, steel and other materials), in vertical or horizontal orientation, before pouring.

High-quality rubber guarantees mechanical resistance and durability over time; certified hydraulic seal up to 5 bar for diameters from DN 32 to DN 315 mm, and up to 4 bar for diameters from DN 355 mm up to DN 1400 mm. Each model is supplied complete with stainless steel clamps.
