This discloses a protective strip 4 adapted for placement above an elongate underground object. The strip comprises a non-planar elongate member having opposite end portions, and in cross section includes a relatively deeper and wider middle arcuate portion and a pair of relatively shallower and narrower side arcuate portions. The underside of one end portion is generally complementary to the topside of the other end portion such that when a plurality of such strips are laid longitudinally with their adjacent end portions overlapped, the end portion of one strip 4 nests with the end portion of an adjacent strip 4A to resist lateral movement there between .
