ABSTRACT:
A tubular structure, such as a sewer, is lined by the use of long length elements having edge formations which facilitate a number of the elements being arranged in a side-by-side interlocked configuration within the tunnel structure. At least some of the elements are formed with a cavity into which a settable compound may be injected thereby to strengthen the lining when set. Preferably the elements are relatively flexible prior to injection with the settable compound so as to facilitate storage of long lengths on a drum.
