A flexible, tube impregnated with epoxy resin is inserted via existing inspection shafts
by cable winch into the pipe section to be renovated. Then the tube is expanded using
compressed air and pressed against the pipe wall. The hardening of the resin takes
place under pressure by blowing in steam. A jointless cladding is created which fits
tightly without annulargap to the existing pipe.
