Dual Calderdale is an interlocking flat concrete tile with an engineered central
groove designed to give the appearance of smaller format slates.
Dual Calderdale should be laid quarter bond. The correct pattern is obtained
by starting / finishing at verges using half and three-quarter width tiles, cut-on-site.
