Correct Adhesive For Garage Floor Tiles

[peteablard]

I can't remember who it was made by(I will find out) but I used some insulation boards a few weeks ago that were far more sturdy than anything I've used before. It would be worth a phone call to the manufacturer to ask their opinion. I know cars are heavy but the weight is spread over four points of contact, each point approximately 25-30" square. I think it might work. You could always stick a couple of boards down,tile them and drive over them, park on them overnight etc.

Thanks Peteablard, fingers crossed that you can remember . I know that (some) car dealerships have underfloor heating with tiles on the top, so they must have a solution that can deal with the loads (as you say about 6-700 kg per corner for a heavy 4x4).

If it's a 4x4 then the tyres are bigger so the point of contact is greater, in terms of point loading per square inch it's probably not much different to a smaller car with small tyres..... I think! A layer the of fibre reinforced SLC over the boards would help too.

I measured my car; the tyre patch is about 250x100mm (10x4") with a total weight of 1500kg. This gives just under 10kg per square inch. That doesn't sound excessive to me. Marmox is rated at 40 tonnes per m2, which is 26 kg per square inch. 10x4" could hardly be described as a point load?
What thickness of FRSLC would you recommend?

I've had a bit of a think about this and I'm confident it's possible. There isn't essentially going to be any point loading as it'll be spread over a 600x600mm (0.36 m2) tile. Now, marmox say their boards can cope with 40 tonnes per m2 so with a tile + adhesive ontop you'd have to have an immense amount of weight to get any compression. Even a 3000kg van is only 750kg at each corner which is well within the capabilities of the products and each tyre has a contact patch of around 200x200mm so, not exactly a stiletto!
It is maybe worth doing a test beforehand but, a 20mm board, then an S1 adhesive (tilemaster setaflex) or if you really want the belt and braces approach an S2 (tilemaster ultimate), then a grade 4/5 porcelain tile, would be my choice.

You posted while I was writing my essay! Some similar figures!

We've put electric UFH down in a few domestic garages - usually to keep the Porche warm!

All totally pointless of course if the tiles are then dot n dabbed!

Thanks Bri - that really helps. Will start insulation and drywall in a month or so, so tiling is still a little way off, which gives me time to experiment.

Make sure you flat the back of each tile also to fill any frogs. Or undulations in tile this'll help strengthen the tile and relate a solid bed
