Paving is more expensive compared to other options for a number of reasons. First of all, pavers are quite durable and will serve you longer than, for example, poured concrete. Secondly, it’s easier to maintain: for example, if something happens with a stone or a slab, you can replace just that element without the need to repair the whole backyard. Another thing is that a paved backyard usually drives the property value up, which is something you may consider for your future. Paving is also more labor intensive than other options, which plays its part in high costs. However, you can save money in this particular aspect by installing it yourself.
