For patios, walkways and pool decks where a large size slab is preferred but budget is a concern, Metro Slab is an excellent choice. Available in grey, black and tan, this 15” x 30” unit creates a clean, modern look. A 6cm thickness makes the units easier to handle but means that it is not appropriate for vehicular loads.
