Generated explanation

Two cutaway views show exterior drainage treatments at cracks in concrete foundation walls beneath wood-framed walls and horizontal siding. Method A places a vertical wooden box against the foundation over the crack, holding soil away and allowing water to drain down toward drainage tile, as described in the annotation.

Both treatments extend below the illustrated grade plane, with their upper ends exposed above it.
