This study proposes an approach to produce a jammed architectural structure without human intervention to clog remote fractures with large widths. Granular particles, slender members, and two-dimensional elements are fabricated and programmed to build a self-assembled three-dimensional architecture. Shape and surface properties of individual components can be properly designed to form mechanical interlocks between components granting mechanical stability. We use the shape memory effect of polymers to fabricate components, the size of which are about an order of magnitude smaller than the width of target fractures. Size limitation imposed by equipment, injecting/circulating individual components, makes simple enlargement of particles ineffective. Graphical abstract: [Figure not available: see fulltext.].
