Covering unit

A covering unit for use in combination with other ones of said covering units for covering a surface, the covering unit having a generally hexagonal body comprising:

• a first, a second and a third pair of opposed and substantially parallel sides for defining said generally hexagonal body;
• wherein:
• each of said sides of each of said pairs has a central point of angular symmetry;
• the second and third pairs of sides are substantially similar to each other while the first pair of sides is substantially longer and different from the second and third pairs of sides;
• and
• the sides of the second and third pairs are provided with at least one split deviation along their length arranged so that each side of said second pair is a rotational image of the sides of said third pair, whereby in use in combination with said other covering units:
• each one of said sides is matingly engageable with the sides of an equivalent pair of sides of a neighbouring covering unit;
• and
• said covering unit has a central point of angular symmetry and is matingly engageable with a plurality of neighbouring covering unit in either a similar orientation or in an orientation of 180°;
• wherein the sides of the first pair are each provided with at least one split deviation along their length arranged so that each side of said first pair is a rotational image of the other one, and wherein said covering unit is engageable with the plurality of neighbouring covering units in staggered rows.
