My biggest tiling job yet

Supercar Storage Project - http://www.tilersforums.com/threads/supercar-storage-project.81219/page-3

This was done on a 400mm concrete floor, approx 15x7.5m. No expansion joints so I split it into 3 bays with expansion joints, primed and fixed with tile master, as per TM's recommendations, 2nd floor just completed so will start a new thread later

the size of tiles on 50 mm screed on kingspan 120 mm is the problem. 900 or 300 the stresses from the cars are the same 2 ton car on 4 points of contact approx 90 cm2 for each tyre the floor is going to crack with out a doughy the screed is too thin

Interesting point - 50mm screed on kingspan - would that be strong enough for driving on? @Ajax123

Standard gypsol classic has compressive strength of minimum C25 and Kingspan has a compressive strength of 150kPa. If the Aston Martin weighs 2tonnes that's 2000kg so 500kg on each wheel. That will exert 0.5kN force. So it is perfectly strong enough. Done loads of garages and car showrooms. Never had an issue

But because they are pneumatic tyres equally space on a solid chassis it acts as a uniformly distributed load so the actual down force is much less than would be expected. Lost count of the number of garages I've done in flowing screed over the years. Never had an issue with weights. I think the heaviest I know of is a hummer. Unless a light aircraft weighs more... done quite a few light aircraft hangars as well.

Brilliant, thanks Alan.

Ajax. I was starting to get disheartened about this job until you came along. I can't really get away from doing this job as the guy is one of my bosses. I feel a bit more comfortable after your comments but what about expansion joints in the tiles. Could I get away with tiling it in four sections and would I need a solid bed of adhesive or maybe use a wall trowel notched to10mm deep. Cheers for your input. In fact thanks to everyone who's commented.

Aston's are front end heavy so it'd be more like .65 on the front and .35 on the rear maybe lol

A 10mm trowel Carl, is the last thing you want to be using.
