Rust specifically designed the block with such versatility in mind:

“When used for retaining, the 4×4 Multi Step block has a unique design that allows you to simply stack up the units without mortar, and the corner interlock gently handles convex and concave curves. The wall angle can vary from vertical to shallow slopes, and steps can be created by turning the block on its side. It can also be rotated for four different elevation choices, and the design allows you to make plants part of your wall.”

Create seating and stairs with retaining blocks

Fifteen years ago Holger Rust, owner of Terraforce – a local and international pre-cast concrete block licensor – developed a new retaining block, the Multi 4×4 Step block: a light, dry-stack concrete unit, generally used for constructing low terrace walls, stairs and seating arrangements.

Aimed at providing efficient and economical steps in conjunction with the original retaining blocks of his design, they soon became very popular not only for stairway access, but also to provide comfortable, practical stair and seating arrangements at leisure amenities and school sports facilities.

Depending on local conditions and finish required, it may be advantageous to grout the joints with sand/cement slurry. Consult your local dealer about colour matching, further details, design information or a quotation.
