In our free draining sandy soils near the coast it is very rare for water to be a problem. As we get into clay soils amongst the hills then its time for drain pipe and aggregate. The shear mass of the bigger blocks (550lb) we lay (it is after all a mass retaining wall) resists localised hydrostatics much better than segmental walls.
