Setup, Compatibility & Care

When using these blocks, ensure that the substrate is level and clean before applying mortar. The blocks should be kept dry prior to use to maintain optimal structural integrity during the setting process. When cutting blocks to fit, use a handsaw with tungsten carbide-tipped teeth to achieve clean, accurate cuts without excessive waste. Store blocks on a flat, stable surface off the ground using pallets to prevent moisture absorption from the soil and potential impact damage to the edges.
