Abstract
Dual-unit paving systems for covering a surface. The system includes pairs of first and second units. For each pair, the first and second unit have different respective shapes and sizes, and are matingly engageable for forming a hexagonal assembly having six, non-linear sides. The hexagonal assembly includes forming rotational tessellations. The first and second units are also shaped and matingly engageable so as to form horizontally aligned tessellations, as well as vertically aligned tessellations.

A dual-unit paving system for covering a surface, the system comprising:
- a plurality of pairs, each pair comprising a first unit and a second unit, wherein for each pair:
- the first unit has a lower face for facing the ground, an exposed upper face, and sidewalls extending from the lower face, the sidewalls of the first unit including a top side, a bottom side, a left side and a right side;
- the second unit has a lower face for facing the ground, an exposed upper face, and sidewalls extending from the lower face, the sidewalls of the second unit including a top side, a bottom side, a left side and a right side, the second unit having a shape different from a shape of the first unit;
- the bottom side of the first unit has a non-linear, irregular outline matingly engageable with an outline of the top side of the second unit for forming a hexagonal assembly having six non-linear sides, the hexagonal assembly allowing to form rotational tessellations;
- wherein when the first unit and the second unit of a pair are facing one another to form the hexagonal assembly, adjacent sides of the hexagonal assembly are spaced apart by an angle of approximately 120°.
A dual-unit paving system for covering a surface, the system comprising:
- a plurality of pairs, each pair comprising a first unit and a second unit, wherein for each pair:
- the first unit has a lower face for facing the ground, an exposed upper face, and sidewalls extending from the lower face, the sidewalls of the first unit including a top side, a bottom side, a left side and a right side;
- the second unit has a lower face for facing the ground, an exposed upper face, and sidewalls extending from the lower face, the sidewalls of the second unit including a top side, a bottom side, a left side and a right side, the second unit having a shape different from a shape of the first unit;
- the bottom side of the first unit has a non-linear, irregular outline matingly engageable with an outline of the top side of the second unit for forming a hexagonal assembly having six non-linear sides, the hexagonal assembly allowing to form rotational tessellations;
- wherein when the first unit and the second unit of a pair are facing one another to form the hexagonal assembly, the six non-linear sides of the hexagonal assembly are congruent.
