1. A structure-lining apparatus for lining one or more surfaces of a structure formed from curable material cast in a form, the apparatus comprising:
a plurality of panels each panel extending in substantially orthogonal transverse and longitudinal directions, the panels connectable at their respective transverse edges in edge-to-edge connections to provide a structure-lining surface;
a first panel of the plurality of panels comprising:
a first connector component at a first transverse edge of the first panel;
a second connector component, complementary to the first connector component, at a second transverse edge of the first panel;
a third connector component, complementary to the first connector component, between the first and second transverse edges of the first panel;
a fourth connector component, complementary to the first connector component, between and adjacent to the first and third connector components;
a first breakaway component between the second connector component and the third connector component for shortening a transverse length of the first panel;
a second breakaway component between the third connector component and the fourth connector component for shortening the transverse length of the first panel; and
a second panel of the plurality of panels, the second panel edge-adjacent to the first panel and lockingly connectable in an edge-to-edge connection to the first panel by a first complementary connector component complementary and lockingly connectable to the first connector component of the first panel or a second complementary connector component complementary and lockingly connectable to the second, third and fourth connector components of the first panel;
wherein a transverse spacing between the second connector component and the fourth connector component is different than a transverse spacing between the third connector component and the fourth connector component;
wherein the second connector component, the third connector component and the first complementary connector component each comprise a male connector component and the first connector component and the second complementary connector component each comprise a female connector component, each of the male connector components lockingly receivable in each of the female connector components;
wherein the male connector components each comprise a spine protruding from the first panel in the inward-outward direction and extending longitudinally, wherein the spine comprises a first protrusion, the first protrusion comprising a first transverse cross-section that is shaped substantially like an arrowhead.
