# Do outdoor porcelain tiles need a concrete base?
## It depends on the thickness of the tile. Porcelain tiles under 2cm thick usually need to be laid on a concrete base.
It depends on the thickness of the tile.
Porcelain tiles under 2cm thick usually need to be laid on a concrete base. This gives them a strong, even surface, so they don't crack under pressure or movement in the ground beneath.
Porcelain tiles 2cm thick or over are strong and versatile enough to be laid without a concrete base.
This rule is for porcelain. Natural stone paving has its own base requirements, which vary by material, so check the product page or speak to your tiler or project consultant before laying.
