Installation of the Saertex-Liner system
Approval code - PT/299/0610
The Saertex-Liner® system comprises a glass fibre reinforced sleeve which is impregnated with a UV-cure
unsaturated polyester resin. The Saertex-Liner® is available in nominal diameters between 100mm and 1200mm
(S liner) and 100mm to 400mm (M liner).
The liner is delivered to site and winched into place through the existing sewer and inflated The liner was winched into place through the existing sewer, inflated with air to allow a UV light train to pass through the inflated liner. The light train is controlled by computer and allows UV light to penetrate the polyester resin impregnated liner – the resin having a light sensitive catalyst added.
Once the UV light comes in contact with the lining, curing commences - the technique is fast and once the light train has passed a point, the lining at that point is cured consequently the engineer does not have to wait until a number of hours for curing of the full pipeline.
