A concrete stamping system is provided, comprising: a base plate; a handle mounted to the base plate; a vibrator secured to a top of the base plate; and a roller attachment secured to a bottom of the base plate. The roller attachment comprises: a frame; and a plurality of parallel rollers mounted on axles extending across the frame and secured within the frame. When the vibrator is activated, vibrations generated by the vibrator are transmitted through the base plate, through the rollers, and into a stamping mat between the rollers and fresh concrete. The system is rollable across the stamping map by an operator.

A system and associated method constructs a building material from lunar soil. A magnetic sorter magnetically sorts the lunar soil and the system creates a layered surface comprising a microwave susceptible, thermal conductive top layer of lunar soil and a poorly microwave-susceptible and poorly thermally conductive sublayer of lunar soil. A microwave generator generates microwave energy into an antenna and directs the microwave energy onto the top layer of lunar soil to sinter the microwave susceptible, thermal conductive top layer of lunar soil.

A paver system for paving a surface is provided. The paver system includes a plurality of cells interconnected to form a grid. The cells generally include six walls to form a hexagonal shape. The cells share at least two walls with adjacent cells, wherein the grid is arranged having parallel rows and columns of cells defining a parallelogram shaped grid. The grid defines four sides, wherein adjacent sides are not at a right angle, wherein select cells may have one or more walls which include a flexible expansion node, and wherein the cells are adapted to receive a filler.
