Stamped concrete is essentially regular concrete that has been colored to look like stone. Stamped concrete is cheaper than paving stones and also looks almost as good. However there is a downside to this cheap solution. Compared to paving stones concrete is far less durable. Concrete cracking is inevitable over time through either expansion or shrinking from different temperature changes throughout the season also sometimes because of heavy loads going across it. Now these cracks will have to be constantly fixed time and time again and every time costing money. When you receive paving stones they are there to last and it is highly unlikely that when installed correctly by a company like Gappsi who does a professional job you will need very little no maintenance to them fir they are far more durable.
