Abstract
Retaining wall blocks and the walls made from such blocks are disclosed, wherein curved landscapes (i.e. curved profiles and sloping embankments) are easily accommodated without the use of mortar. As well, a modular system of blocks and their manufacture are disclosed wherein some blocks are used in vertical orientations and some in horizontal orientations.
Claims2
A block comprising:
- (a) an upper planar surface;
- (b) a lower planar sub-surface;
- wherein the block is scored to be split into
- (c) first longitudinal sub-block having an upper planar surface with a longitudinal through-channel and a lower planar surface having opposed outer lugs;
- (d) second longitudinal sub-block having an upper planar surface with two opposed blind channels opening outwardly, and a lower planar surface having opposed outer lugs;
- wherein said first sub-block is scored to be further split into:
- (e) first mini-block having an upper planar surface with a longitudinal through-channel and a lower planar surface having opposed outer lugs;
- (f) second mini-block having an upper planar surface with a longitudinal through-channel and a lower planar surface having opposed outer lugs.
