Madoc has the appearance of rustic slate walling which belies its unique easy-build interlocking Z-shaped block. It can be dry laid up to three blocks high, but for stability, bond with Bradstone Walling Adhesive.

Madoc walling blocks are faced on three sides for building attractive single-sided walls, step risers and raised planters.

Madoc can be left unpointed, although for a professional finish, point the full block joints.
