Fill Permeable Gaps with Small Stone

What happens here

Once the permeable border pavers are laid and securely in place, fill the wider gaps between them with a very small, clean, and permeable stone. This is distinct from using polymeric sand, which solidifies and prevents drainage. The permeable stone allows water to easily pass through the joints and into the prepared permeable sub-base below, effectively draining the patio surface and preventing water from sitting. The video specifically refers to this as 'very, very small stone.'

Goal: Create open, draining joints in the border pavers for water infiltration.
