WebAs seen in the video or during any rainfall, a raindrop hits the ground with significant force. This force could dislodge the particles, leading to runoff and erosion discussed in the … 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.
