However, the two options below have proven to be the best in practice:
• Foundation slab (base plate)
• Strip foundation

Once the concrete slab has been completed and dried out, we recommend torching it
with roofing felt or torch-on felt in order to seal it completely.

steel mesh mats must be laid in the concrete (reinforced) in order to achieve maximum
stability and protect the slab from cracking.
