Permeable pavers are all the rage. #pavers #paverpatio #hardscape #techobloc #permeability

What happens here

As water is poured onto the paver surface, carefully observe its behavior. Notice how the water does not sheet or pool on the top of the pavers but instead rapidly disappears into the wide, aggregate-filled joints between each paver unit. This visual demonstration clearly shows the immediate drainage capability of the permeable surface. The open joints, filled with crushed stone, are the primary pathways for surface water to enter the system, effectively managing rainfall directly at the source.

Goal: Visually track how water, when applied, drains quickly and completely through the joints of the permeable pavers, preventing surface pooling.
