Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks - Part 9: Lining with a rigidly anchored plastics inner layer (ISO 11296-9:2022)
This document, in conjunction with ISO 11296‑1, specifies the requirements and test methods for pipes and fittings for the renovation of underground non-pressure drainage and sewerage networks by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout.
This document is applicable to plastics inner layers and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system.
NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.

Dieses Dokument legt in Verbindung mit ISO 11296 1 die Anforderungen und Prüfverfahren für Rohre und Formstücke fest, die für die Renovierung erdverlegter druckloser Entwässerungsnetze (Freispiegelleitungen) durch Lining mit einem einzelnen biegesteifen Ringraum aus einem tragenden zementhaltigen Mörtel hinter einer Kunststoffauskleidung verwendet werden. Diese Kunststoffauskleidung dient als Dauerform, die mit dem Mörtel verankert ist.
Dieses Dokument ist anwendbar für Kunststoffauskleidungen und Mörtelsysteme mit oder ohne Stahlbewehrung. Es behandelt nicht die statische Auslegung des Lining-Systems.
ANMERKUNG Es gibt Systeme mit mehreren Ringräumen, die jedoch durch Patentrechte geschützt sind und in diesem Dokument nicht behandelt werden.

Introduction
This document is a part of a family of system standards for plastics piping systems of various materials
used for the renovation of existing pipelines in a specified application area. System standards for
renovation deal with the following applications:
— the ISO 11296 series, Plastics piping systems for renovation of underground non-pressure drainage and
sewerage networks (this series);
— the ISO 11297 series, Plastics piping systems for renovation of underground drainage and sewerage
networks under pressure;
— the ISO 11298 series, Plastics piping systems for renovation of underground water supply networks;
— the ISO 11299 series, Plastics piping systems for renovation of underground gas supply networks.
These system standards are distinguished from those for conventionally-installed plastics piping
systems by the requirement to verify certain characteristics in the “as-installed condition”, after site
processing. This is in addition to specifying requirements for plastics piping system components “as
manufactured”.
Each of the system standards series comprises a:
— Part 1: General
and all applicable renovation technique family-related parts, which for non-pressure drainage and
sewerage networks includes or potentially includes the following:
— Part 2: Lining with continuous pipes;
— Part 3: Lining with close-fit pipes;
— Part 4: Lining with cured-in-place pipes;
— Part 5: Lining with discrete pipes;
— Part 7: Lining with spirally-wound pipes;
— Part 8: Lining with pipe segments;
— Part 9: Lining with rigidly anchored plastics inner layer (this document);
— Part 10: Lining with sprayed polymeric materials.
The requirements for any given renovation technique family are specified in Part 1, applied
in conjunction with the relevant other part. For example, both ISO 11296-1 and this document
together specify the requirements relating to lining with a rigidly anchored plastics inner layer. For
complementary information, see ISO 11296-1. Not all technique families are pertinent to every area of
application and this is reflected in the part numbers included in each system standard series.
A consistent structure of clause headings has been adopted for all parts of the ISO 11296 series in order
to facilitate direct comparisons across renovation technique families.
Figure 1 shows the common part and clause structure and the relationship between ISO 11296-1 and
the system standards for other application areas.

INTERNATIONAL STANDARD ISO 11296-9:2022(E)
Plastics piping systems for renovation of underground
non-pressure drainage and sewerage networks —
Part 9:
Lining with a rigidly anchored plastics inner layer
1 Scope
This document, in conjunction with ISO 11296-1, specifies the requirements and test methods for pipes
and fittings for the renovation of underground non-pressure drainage and sewerage networks by lining
with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This
plastics layer serves as permanent formwork anchored to the grout.
This document is applicable to plastics inner layers and grout systems with or without steel
reinforcement. It does not apply to the structural design of the lining system.
NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered
by this document.

Further characteristics of the fresh grout system which have an influence for a specific RAPL product on:
— complete filling of the annular space; and/or
— achievement of the required characteristics of the cured grout system
shall be declared with corresponding test methods in the installation manual for that product.
b
The modified diameter is needed because the grain size of mortar mixes used for this application is typically larger than
that used for other common applications of cementitious injection products.
c
The preparation and the conditioning of the prismatic test specimens shall be as specified in EN 196-1. Mixing ratio and
mixing technology shall be that actually used in the installation as declared by the manufacturer.
d
Where self-levelling grout of high fluidity is used, such that the flow diameter exceeds the 300 mm diameter of the table
plate of the standard EN 1015-3 test apparatus, the test shall be modified as follows:
— truncated conical mould replaced by simple cylindrical mould of internal diameter 50 mm and height 100 mm;
— time of first flow diameter measurement reduced to 3 min from completion of mixing;
— if necessary, use of a larger table plate (width or diameter of 500 mm recommended).

The dimensions and section properties including tolerances of the plastics inner layer shall in all cases
be declared.
5.4.2 Studded PE sheet
An example cross-section of a studded PE sheet including a double hot wedge welded seam is
illustrated in Figure 3. The geometrical design of the integral stud anchors shall be such as to meet
the requirements for the bond between anchored inner layer and grout depending on the RAPL lining
system. The waterway wall thickness, e , of the PE sheet shall be declared and shall not less than

2,5 mm. The shape and spacing in two dimensions of the integral stud anchors shall also be declared
and shall have an overall height, e , of not less than 10 mm. The maximum spacing, s , of studs either

side of a welded seam shall not exceed 1,25s, where s is the standard spacing within the sheet in the
same direction.
