This clause establishes a classification of renovation techniques into families, where renovation is applied to continuous lengths of drain or sewer usually between two or more access points. Individual techniques shall be classified into families according to 5.2 to 5.9 where the different renovation technique families are defined and their respective features, including materials, applications, as well as geometric, performance and installation characteristics, are described.
a Outside the scope of this European Standard. b Other renovation techniques, which do not fit into the above families, are outside the scope of this European Standard which covers only technique families commonly available at the time of drafting.

100 mm for Method A, 150 mm for Method B; − typical maximum size:
1 200 mm for Method A, 600 mm for Method B; − typical maximum length:
300 m for Method A, 100 m for Method B; − some Method A techniques capable of accommodating bends Performance: − significant reduction in hydraulic (volumetric and flow) capacity for Method A; minimal reduction of volumetric capacity with increase in flow due to reduced friction possible for Method B; − uniform gradient cannot be restored; − structural rehabilitation is possible; − abrasion resistance depends on material; − chemical resistance depends on material Installation characteristics: a) pipes manufactured or prior assembled into the continuous length required; for Method B pipes of non standard outside diameter required (max. 10 mm less than host pipe inside diameter); b) insertion possible by pushing and/or pulling for Method A; for Method B only by pulling with use of re-rounding head; c) surface working space: storage of the whole insertion length required on surface: 1) small diameters (typically ≤ 180 mm) can be supplied on coils, small space; 2) larger diameters: supplied in straight lengths requiring greater storage and working space; d) access to the existing pipeline: generally requires local excavation; e) technique does not rely on adhesion to host pipe; f) flow diversion is typically required for installation; g) the annular space is typically grouted for Method A but not applicable to Method B; h) reconnection of laterals: generally requires excavation for Method A except in man entry sizes; for Method B reconnection from inside possible
5.3 Lining with close-fit pipes 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. Two possible methods of lining with close fit pipes are shown in Figure 3 and Table 2: − Method A: reduction in the pipe manufacturing plant; the pipe is usually supplied coiled on a reel from which it is directly inserted; − Method B: reduction on site (typically applied to pressure pipelines only); the pipe is fed through diameter reduction or folding equipment and simultaneously inserted.

100 mm; − typical maximum size: 2 800 mm; − typical maximum length: Method A: 600 m, Method B: 250 m; − bends can be accommodated Performance: − minimal reduction in volumetric capacity; increase in flow due to reduced friction possible; − restoring of invert is not possible; − structural rehabilitation is possible; − abrasion resistance depends on wall structure; − chemical resistance mainly depends on resin type Installation characteristics: a) insertion of the impregnated tube, prior to curing, can be achieved by:
1) inverting into position with fluid pressure only (water or air) or 2) winching into place and then inflating; 3) combinations of Methods a) and b) are also possible;
b) the curing process can be initiated or accelerated by either:
1) heat (hot water, steam or electrical heating elements); UV radiation or 2) ambient temperature; c) surface working space: generally minimal, varies with technique; d) access: entry via existing manhole or small excavation possible; e) structural effect does not rely on adhesion to host pipe; f) flow diversion required; g) grouting of annular space not necessary; h) re-opening of laterals from inside is possible; i) reconnection of laterals: 1) gravity pipelines: possible from inside (re-opening and tight connection); 2) in pressure applications: generally requires excavation, except in man entry sizes
5.5 Lining with discrete pipes Lining with short lengths of pipe which are jointed to form a continuous pipe one by one during insertion (see Figure 5 and Table 4). Discrete pipes can be installed by pushing (Method A), by pulling (Method B) or by individual pipe placement (Method C). NOTE Use of a re-rounding head with as described in 5.2 is also possible for discrete pipes Method B. SIST EN 15885:2011

600 mm; Method C:
4 000 mm; − typical maximum length:
150 m; − Bends: bends can generally not be accommodated for Method A and B; bends with large radii can be accommodated for Method C Performance: − significant reduction in hydraulic (volumetric and flow) capacity for Method A; minimal reduction of volumetric capacity for Method B where re-rounding head is used, with increase in flow due to reduced friction possible; for Method C, reduction in capacity dependent on annular space and diameter/thickness ratio; − uniform gradient can be restored using Method C in man-entry pipes; − structural rehabilitation is possible; − abrasion resistance depends on material; − chemical resistance depends on material Installation characteristics: − the type of joint is a significant feature of each technique; − pipe joints can be locked (end load bearing) or unlocked; − surface working space: no particular constraint; − short pipe lengths may allow insertion from existing manholes (Methods A and B); − access to the existing pipeline:
generally through manholes but requires local excavation for man entry sizes; − technique does not rely on adhesion on host pipe; − flow diversion is typically required for installation and grouting; − the annular space is typically grouted, except for Method B when re-rounding and non standard lining pipe outside diameter is used (see 5.2); − reconnection of laterals: generally requires excavation; except in man entry sizes; for Method B, when a re-rounding head is used, reconnection from inside possible
5.6 Lining with spirally-wound pipes Lining with a profiled strip, spirally wound to form a continuous pipe after installation (see Figure 6 and Table 5). This technique family does not rely on any contribution from grout for its structural performance. NOTE For this technique the continuous pipe after installation is the structural element, with minimum ring stiffness conforming to EN 13566-1. SIST EN 15885:2011
