Houseliner is CR072 Certified!

SP’s certification unit RISE has, in collaboration with BRiF, the Relining in Real Estate industry association in Sweden, developed a new certification rule, CR072, for relining methods. The certification rule enables P-marking of installations as well as products via SP.

The methods apply to pipes and pipe parts for waste and storm water in property

Lining with flexible liners and fittings impregnated with resin.

This certification rule covers technical information for self-supporting relining systems for use in internal renovation of stormwater and waste water systems in normal residential environments within buildings.

  • However, we would like to point out that the certification rule does not apply to the relining of pipe systems for tap water, says Ronald Green, product certifier at SP.

A P-marked building product gives the developer and the property owner security in their product choice.

With the P-mark, SP certifies that the product meets the Swedish Housing Agency’s building regulations for the intended use described in the certificate.


  • Age tested for 50 years
  • Safe relining method
  • Guarantees quality installations
