Expanded Clay Aggregate (ECA®) tile laying technique is between 4 – 5 mm groove between tiles, and this is the same as conventional ceramic tile laying.

Groove Fill

After laying the tile, fill the joint by mixture of very fine sand with normal cement mortar, or with any other cementitious material (resin, lime, etc.)
