- Install DPM/Radon barrier.

- Position boards across floor in broken bond.
- Position boards tightly against each other including at edges and around obstacles.
- Lay VCL, lap and then seal every joint.
- Pour and tamp slab.

Prior to pouring slab, test any embedded services. To prevent damage to Ballytherm boards use barrow boards whilst pouring the slab and screed. When levelling the slab, protect exposed edges of the boards. Finally, be certain when fitting boards together to obtain as close a fit as possible.
