Need a neat and easy to install staircase? The Terraforce 4×4 Step block, a light, dry-stack concrete unit, is ideally suited for efficient and economical steps, either in combination with the Terraforce L range blocks or for freestanding staircases.
The step can be as wide as you wish; four blocks in a row will result in a flight 800 mm wide. With an overlap of 50mm, a single block tread of 350mm and a riser of 150mm is obtained, although a double row will work well on a gentle slope and where the steps curve. After positioning the blocks, push mortar into the hollow of each block, but only if the blocks are supplied without the internal T-bar, dependant on the manufacturer.
Compact the soil behind each step and ensure that the ground is absolutely level before you start laying the next row of blocks. In some instances, it may be advisable to place a bedding layer of stabilised sand below the blocks (5% cement added).
