How They Resist Vertical, Horizontal,
and Rotational Forces

Porous Concrete Pavers

Basically, permeable or porous paving resists forces by creating an interlock between pavers.

Vertical loads are transferred to surrounding units by the sand in the joints.

Horizontal loads from braking and accelerating are handled via laying patterns and paver shapes that allow dispersion of forces on two axes. The Herringbone pattern provides a particularly effective interlock.

Rotational loads can be resisted by pavers that are: sufficiently thick, placed close enough together, and have a confining stationary edge.
