Corrosion Resistance Thedeteriorationofasewerorculvertisoftenacceleratedby corrosive gasses and the oxidization of HydrogenSulfideintoSulfuricAcid.
Soft mortar is not always easily identified by CCTVsurveys. For Man Entry sewers manual inspection isrecommended. Most structural failures in sewers arecaused by insufficient tensile capacity. Corrosion willcontributetothisreductioninstrength.
The resins used by Channeline are highly resistant tosewergasesandmosttradeeffluent.Adetailedcorrosionresistance guide is available from your ChannelineRepresentativeorcanbedownloadedfromourwebsite.
Barcol Hardness and Abrasion ResistanceThe high quality gel coat resins and surface veils usedin the manufacture of Channeline panels provide an exceptionaldegreeofresistancetoimpactandabrasion.

Hydraulic CapacityThehydrauliccapacityofasewerorculvertisdependenton the cross sectional area of the unit and the surface roughness of the sewer or culvert wall. Collapsed andprotruding sections of the host pipe wall can greatlyreduce the cross sectional area and increase the friction coefficient of the unit, thus dramatically reducing itshydrauliccapacity.
Afeaturecommontonearlyallsewerandculvertrenovationprocesses is that the internal surface roughness of theexistingsewerorculvertisreduced,i.e.improvedfromahydraulicpointofview.Thus,althoughthereisfrequentlyalossofcrosssectionalareaassociatedwiththerenovationwork,thisisgenerallycounteractedbytheimprovedflow-carryingcharacteristicsoftheupgradedsewer.
