Abstract
A retaining wall and block are described herein for use in landscaping, gardening and the like. The block is formed from concrete and has an uneven face to replicate layers of flat stone. An elongated groove in the top of each block provides for reception of mating studs of upper contiguous blocks. The elongated groove is sized to allow the blocks to be turned and moved depending on the type and design of the particular wall being constructed. The ends of the blocks are biased to allow easy rotation and placement when building a curved or circular wall. A filler is provided for placement within the elongated groove of the blocks in the top tier of the retaining wall to provide for a smooth, flush surface.
Claims19
A retaining wall block comprising:
- a body, said body comprising a front, a back, a top, a bottom and a pair of ends, said front wider than said back, said top defining an elongated groove and a drainage opening, said drainage opening in fluid communication with said groove proximate said back for drainage of said top from said front to said back, a pair of mating studs, said mating studs attached to said bottom, whereby said retaining wall block can be used as a lower block in a multi-tiered wall with said groove sized to allow the mating studs of a contiguous upper block to mate therewith and to rotate and move in any horizontal direction for selectively offsetting the upper block.
A rigid retaining wall block comprising:
- a back, a top, said top defining an elongated groove and a drainage opening, said drainage opening in fluid communication with said groove proximate said back, a bottom, a pair of mating studs, said mating studs spaced along said bottom, a face, said face defining a plurality of multi-layers, said face wider than said back, said groove sized to allow one or more contiguous similar blocks to mate thereon and to selectively rotate and move in any horizontal direction while mated.
A retaining wall comprising a plurality of tiers of rigid wall blocks, said tiers comprising a top tier, said wall blocks matingly engaged, each of said blocks selectively rotatable and selectively moveable in any horizontal direction during engagement with contiguous blocks wherein each of the said wall blocks comprises a top, a front, a back, said top defining an elongated groove and a drainage opening, and said groove in fluid communication with said drainage opening proximate said back whereby drainage moves backwardly from said front to said back.
