Exterior substrate For Victorian tiles.

[Spencer]

I’m pricing a job which is 26m2 of front garden path to be tiled with old English geometric tiles.

The old concrete path will be taken up, and a new base putting down. I will be getting a firm in to do this work, but I want the best solution for the base, that will take these tiles without future issue.

My thinking is a concrete slab onto hardcore, then a screed top?

I would be grateful for experienced advice on this.

Well compacted hardcore base, 150 reinforced concrete stab and plenty expansion joints.

Make sure the concrete/screed cures for at least three weeks. A decoupling layer is a good idea, but most of the popular ones are only really suitable for indoors. Orbry Permalayer will work outside;
