As part of the town planning requirement, the council require a 'Porous' concrete driveway. I was wondering given this is not a normal concrete, how common it is to have 'Porous' Exposed aggregate concrete driveway? instead of just a normal exposed aggregate driveway?
Any idea in relation to the cost increased with 'Porous' comparing to the normal 'Exposed Aggregate' Concrete?
