Crazy paving is a specific type of paving style that is said to have originated in ancient Rome. Although the design looks great, the concept is simple – irregularly sized paving stones laid down onto the ground in a haphazard manner. Due to the crazed appearance, the notion that it is an easy, cheap form of paving is widely held. However, this is not necessarily the case. In fact, often, the opposite is true. From the perspective of the contractor, regular paving is often easier to lay than crazy paving. This is because the irregular shapes of crazy paving make it very difficult to arrange without large gaps between the paving stones. These gaps can be filled with mortar. Doing so, however, makes the appearance less appealing. So, now that you have an idea about what crazy paving is, here are some facts about crazy paving that you might not know:


  • Different materials can be used in crazy paving: Slate, Quartzite and other materials can all be used in laying crazy paving – there is no dominant stone type. Stone is predominantly used, though, due to the fact that it is naturally irregular in shape. A close number two would be concrete. Concrete comes in irregular shapes when it is broken. Concrete is regularly found broken when it is disposed of. Crazy paving tends to be laid on cement, or something with similar qualities. This helps it to ensure that the slabs are firmly in place and do not budge.
  • It is not always cheaper than traditional paving: A lot of people have the impression that crazy paving is a cheap, simple alternative to regular paving. The idea that it is cheap comes from the fact that broken concrete flags can often be obtained free of charge or at least at a very minimal cost. Whatever the price may be, it will be cheaper than intact units. However, well-laid crazy paving is actually a very difficult task to achieve. Minimising the mortar visible between the gaps is difficult, and requires the contractor to be extremely talented when it comes to arranging the paving stones. However, mortar does not only look unpleasant but it is also the main cause of structural weakness in the paving. Thus, the less mortar, the better. Such skill will cost you.


  • Vehicles can drive on crazy paving, but only if it is laid in a certain way: If heavy loads are regularly going to be moving on top of the crazy paving (such as cars), then the way in which crazy paving is laid is different. In this case, the paving is usually laid on a 100mm-thick bed of C20 concrete, allowing it to handle heavy weights passing above it without breaking apart.
