WebLift thickness. As lift thickness increases, it becomes less likely that a series of interconnected voids can span the entire lift depth. Therefore, as lift thickness increases, permeability decreases. Therefore, lifts with higher density, thicker lifts, and mixes with smaller nominal maximum aggregate sizes are less likely to be permeable.
