Sealing collars for wall penetrations

Wall penetration sealing collars are used to obtain a watertight penetration through a concrete wall when it is crossed by a pipe of any material: steel, cast iron, copper, plastic, fiber-reinforced concrete or ceramic pipes. They can be used in floors, ceilings, pumping station walls, pools, galleries or underground drainage channels.

Advantages:

• An economical and safe method of hydrostatic sealing
• The ideal solution when a permanent installation is required, obtained during casting, without allowing later modifications
• Watertight against groundwater and internal hydrostatic basin pressure
  • Tested at 5 bar pressure – sizes OD 32 – OD 315 mm
  • Tested at 4 bar pressure – sizes OD 355 – OD 1400 mm
