If you are looking for the ULTIMATE in Swimming Pools, then look no further than a Concrete Pool.  There is no nicer or stronger pool than Concrete! It is amazing what can be done with these pools, such as a Perimeter Overflows- this is where the water is right up to the edge of the pool wall. The water will have a reflective mirror like finish.  The majority of all Infinity pools are built with Concrete.  Infinity pools do not have to be built next to the water, they can be built anywhere that you desire this feature. Raised wall pools are very easy to build with Concrete.
