Pipe tundish with integrated step protection insert for setting within the base slab in concrete for optimum sealing to the underground sewer pipe. The product also compensates for any offset (after concreting) between the downpipe and base drain in any direction.

Features and benefits:

  • Axial tolerance compensation.
  • Adhesive ribbon for simple integration of vapour barrier foil.
  • Non-trip installation according to DGUV 38 section 12a due to the step safe insert.
  • Integrated level for position alignment of the tundish.
  • Saves rectangular recesses and therefore complex follow-up work.
  • Simple on-site installation.
  • Gas-tight and watertight connection to the base slab due to the integrated three-ribbed seal.
  • Thermoplastic elastomers (TPE) sealing lips to seal the underground sewage pipe.
  • Step safe insert with perforation and dirt trap grooves can be used during construction to drain the base slab.
  • Undercut for optimum fixing in concrete.
  • Built-in stop for exact pipe positioning.

Tests/ standards:

  • KG pipes to DIN EN 1401.
  • KG 2000 pipes to DIN EN 14758.cations.
