Twenty-four tiles is the size to buy for a small balcony or a landing outside a back door, and the three layout patterns supplied mean the same box can read as straight planks, a checkerboard or a herringbone run. Natural acacia hardwood forms the top of each 12 in square, 1 in thick and pre-finished so it can be rinsed clean with a hose. The polypropylene base clips tile to tile without glue or fasteners and can be cut with a handsaw where a wall gets in the way. Raised diamond ribs beneath hold the wood above the slab so water drains and air moves, which is what keeps the underside from staying damp. Each tile carries 500 lbs; the set weighs 41 lbs.
