Patterns are saw cut into the slab in rectangular and square designs of any size. The slab can have a smooth or sand blasted finish - allowing some aggregate to show through. See below.
When sandstone coloured concrete is laid and rectangle or square patterns are saw cut into the top, the finished effect is a very flat profile similar to an upmarket "Urban Stone" look. But this is achieved without the double cost of having to have a concrete base laid and then urban stone pavers placed on top!
