Drain Lining and Sewer Repair
<back
Following the Closed Circuit Television Survey and reports it may be necessary to perform some form of remedial works to restore the condition of the drain or sewer to a satisfactory state of hydraulic fluidity.
As well as excavations to replace pipe work, “No Dig Technologies” are available such as “Drain Lining” or “Localised Structural Repairs”.
Drain lining involves the insertion of a resin impregnated liner or “sleeve” to the existing pipe; the resins are then “cured” into place using air, water or heat or a combination of these. Upon completion the lining material then becomes the replacement pipe. Any incoming junctions or connections that have been covered by the insertion of the repair method can then be reopened using “Lateral Cutting” equipment.
As an alternative to a full length drain repair a “Localised Structural Repair” can be installed to a small section of the drain or sewer; again this involves a resin impregnated “mat” that is positioned at the point of defect and cured into place. This method of drain repair is recognised as a more cost effective way than lining the whole pipe for just one defect, or as an alternative to excavation. This is particularly useful when only a small section of the pipe is defective, and a more cost efficient alternative can be considered.
