Stair block for use in landscaping and method for use thereof

摘要

A block for an outdoor staircase stair includes an open four-sided block having a web interconnecting opposing sides and transversing the cavity within the block. The web includes vertical voids which extend from the top of the web into the body of the web. Two of the voids are located at the lateral ends of the web. The top parts of the web between the voids are broken out after the block is placed over the ground surface. Each block may be placed such that its front wall rests on the rear wall of the course of blocks below it. The blocks are filled with granular material to within about the thickness of a paving block or brick. Paving blocks are arranged on the granular material within the block such that the tops of the paving blocks are flush with the top of the block. Methods for building a staircase from the blocks and for molding the blocks are also described.
