4×4 Multi Step Block - Terraforce

4×4 Multi Step Block™

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.
