I will be getting my driveway done in the spring but as a alterantive to block paving I have seen a driveway that has had concrete poured on and then impressed then sealed to give a look of block paving and it looked ok .......would anybody recommend it or stay clear of it? costs,it is cheaper or expensive than block paving? I know one good reason that there would be no joints that have to be replaced every couple of years but what are the drawbacks?
