Patio with sleeper retaining wall

[Warwick_Hope]

Laying porcelain tiles onto a solid type 1 base

There is a small sleeper wall (new style sleepers) laid around the edge and want the tiles to overshoot this

Will be bedding the tiles on a full bed of mortar, but don't want to put mortar on top of the sleepers

Large tiles so 90% will be on hardcore

Do I just run a fat bead of silicone or similar on top of the sleepers?

Thanks

Personally I wouldn't overlap. I think there will be too great a risk of movement.

 

In addition I don't think much sticks to pressure treated wood. I can see water getting trapped under the tiles in contact with the wood.
