rehabilitation of pipeline systems
In 4.2 to 4.7, the different renovation technique families are defined and specified by reference to system
standards and the materials and fields of application these cover. In addition, certain general characteristics of
each renovation technique family are described.
4.2 Lining with continuous pipes
Definition: Lining with pipe made continuous for the length of the section to be renovated prior to insertion; the
cross section of the lining pipe remains unchanged (see Figure 2).
NOTE Often referred to as sliplining.

EN 13689:2002 (E)
Figure 2 — Schematic representation of lining with continuous pipes
Relevant system standards: See Bibliography
Materials: PE, PP
Application: Non-pressure and pressure pipelines
Characteristics: - pipes manufactured or prior assembled into the continuous length required;
- in the case of non-pressure pipelines, the annular space is usually grouted;
- some techniques capable of accommodating bends;
- live insertion is possible;
- insertion possible by pushing and/or pulling;
- typical diameter range: up to 1 600 mm;
- reduction in capacity significant.
4.3 Lining with close-fit pipes
Definition: Lining with a continuous pipe for which the cross section is reduced to facilitate installation and
reverted after installation to provide a close fit to the existing pipe (see Figure 3).
NOTE For the reduction in cross-section there are two options:
a) reduction in the pipe manufacturing plant; the pipe is usually supplied coiled on a reel from which it is directly
inserted;
b) reduction on site; the pipe is usually fed through the reduction equipment and simultaneously inserted in one
continuous string.

a) Installation of a pipe reduced in cross-section in the pipe manufacturing plant
b) Installation of a pipe reduced in cross-section on site
Figure 3 — Schematic representations of lining with close-fit pipes
Relevant system standards: See Bibliography
Materials: PE, PVC-U
Application: Non-pressure and pressure pipelines
Characteristics: - lining pipe first reduced in size by mechanical or thermo-mechanical means
(in the manufacturing plant or on site), inserted and then reverted by relief of
installation forces or application of heat and/or pressure;
- lining can be accomplished either via an insertion pit or via a manhole (in the
case of sewers), the latter requires a pipe with sufficient axial flexibility;
- no grouting required;
- some techniques capable of accommodating bends;
- individual techniques differ substantially in the degree of skill required;
- can be installed in long lengths;
- typical diameter ranges:
a) factory-reduced pipe: up to 500 mm;
b) site-reduced pipe: up to 1 500 mm;
- minimal reduction in capacity; increase in flow possible.

4.4 Lining with cured-in-place pipes
Definition: Lining with a flexible tube impregnated with a thermosetting resin which produces a pipe after resin
cure (see Figure 4).
Figure 4 — Schematic representation of lining with cured-in-place pipes
Relevant system standards: See Bibliography
Materials: A composite consisting of a reinforced or unreinforced fabric carrier material
impregnated with thermosetting resin, which may include optional internal
and/or external membranes. For details, see the relevant standard.
Application: Non-pressure and pressure pipelines
Characteristics: - insertion of the impregnated tube, prior to curing, may be achieved by either:
a) winching into place and then inflating; or
b) everting into position with fluid pressure only (water or air); or
c) winching one tube in place and then inflating with a second, everted,
tube;
- the curing process may be initiated or accelerated by either:
a) heat (hot water, steam or electrical heating elements); or
b) UV radiation;
- entry via existing manhole or small excavation possible;
- grouting not required;
- techniques capable of accommodating bends and non-circular cross-
sectional shapes;
- individual techniques require relatively high degree of skill;
- curing period depends on job size and initiation system used;
- typical diameter range: up to 2 800 mm;
- minimal reduction in capacity; increase in flow possible.
4.5 Lining with discrete pipes
Definition: Lining with pipes shorter than the section to be renovated which are jointed to form a continuous
pipe only during insertion; the cross section of the lining pipe remains unchanged (see Figure 5).

Relevant system standards: See Bibliography
Materials: PE, PP, PVC-U, GRP
Application: Non-pressure pipelines
Characteristics: - the type of joint is a significant feature of each technique;
- pipe joints may be locked (end load bearing) or unlocked;
- short pipe lengths may allow insertion from existing manholes;
- the annular space is usually grouted;
- typical diameter range: up to 4 000 mm;
- reduction in capacity generally significant.
4.6 Lining with inserted hoses
Definition: Lining with a reinforced hose which is either permanently reverted to provide a pipe after installation
or inflates when fluid is transported under pressure (see Figure 6).

Characteristics: - hose pulled with folded cross-section into existing pipeline and then either:
a) reverted by inflation with steam to a self-supporting circular shape; or
b) remains collapsed until pressurised;
- may be loose-fitting or close-fitting;
- requires special fittings at ends and service connections;

5 Design
NOTE It is the responsibility of the designer/system owner to choose and design the renovation system. This standard
provides information only to guide the processes of choice and design.
5.1 Liner functions and selection criteria
Before a renovation technique is chosen, the required function of the liner in service shall be determined in
accordance with EN 752-5, EN 805 or EN 12007-4, for drain and sewer applications, water supply applications
and gas supply applications respectively. Liner functions generally include one or more of the following:
a) separation of the inner surface of the existing pipeline from the transported fluid to prevent mutual adverse
reactions (e.g. corrosion of the existing pipeline by aggressive water);
b) sealing of the existing pipeline against infiltration of ground water or exfiltration of the transported fluid
through leaking joints, cracks or holes;
c) stabilising or strengthening of the existing pipeline structure (e.g. where corrosion has resulte
