Well this sucks (heads up)

[jay]

Tiled a patio about a month back .Got a call Sunday morning tiles have cracked , patio is 2nd story timber and steel construction with 19mm compressed sheet as the lining for the tiles. sheets are staggered and epoxy jointed and screwed in place , tiling /primed with sbr Hydroban waterproofing all joints reinforced taped . laticrete anti fracture layed over the top (comes in a roll 900mm wide by whatever length self adhesive) tiles fixed wit lati gold natural grout and silicone to all internal corners ..patio is water proof with no sigh's of leaks .Have a bo peep at the pics and see what you make of it

the problem has been found but would be interested in what you believe to be the issue

Thanks

is this not over tightning of the rails around the perimiter. They all seem to be in the areas the fixings would be?

nope not over tightening railing was installed a week before cracking occurred

 

[radim]

cracks around fixings only.is it rail movement?

 

[suave]

strange! deffo looks like something to do with that railing,nice job may i say

 

[jwatson]

think this is a mull over, with a cup of tea joby. will have a good think about this one

 

[Sean Kelly]

Has someone been 'stress testing' the rail, and was a bit too heavy handed? Or has someone been jumping off the outside of the rail? I bet you felt sick when the call came in. Cheers Sean

it looks like its to do with the railings, possible expansion of the joists under the tiles. it don't look like your fault.

 

[Stewart]

When the hole was drilled through the tile for the railings, did they make it bigger than the bolt to allow for movement and expansion....

Something very heavy was "rested" on the rail ?

 

[doug boardley]

I'm guessing that the wind has moved the railings and cracked the tiles.

 

[user123]

I agree with Mike, the wood joists, open to the weather still, expanded, moved and distorted the fixing of the rails above.. also the bolts are pretty close to the edge of the wood, making possible movement worse, if they had been in the middle of the wood the movement may have been a little less. In picture 2 the wood looks damp and cracked around the bolt... and there seems to be little room for expansion of the wood joists built in anyhow.

Surely it has got to be something to do with the rails unless they did something really unusual like having a grand piano hoisted up over the rails?

 

[Dan]

That has to be something to do with the rails. And I'd go with the above reply of it being something to do with the holes not being drilled big enough to allow for expansion/retraction.

Doesn't look like deflection. It isn't happening anywhere else but near the rail fixings. So it sounds like the rail company will suffer the replacement and fixing of them?

 

[suave]

anutha shot for me,has the rails expanded from the heat from the sun?

 

[Alan.P]

The hand rail hasn't been tightened and it's been flapping in the wind, this has transfered movent to the bolts onto the tiles forcing them to crack ?

 

[Gazzer]

I agree with Doug. Or it could be people leaning on the railing.

 

[The Legend; Phil Hobson RIP]

I would go along with expansion, or movment on fixings

 

[doug boardley]

is the barrier glass Jay? I've heard that in extreme cases the glass can expand, (although it won't be that hot down under yet), so it could be putting stress on balustrade.

 

[Andy Allen]

they had a party, and a 25 stone fat git lent on the rail?...

 

[tommyzooom]

The railing has been tightened reasonably tight, then the joists expanded, putting excessive pressure on the tiles under the railing???

 

[Aston]

They appear to be stress cracks to me, so i go along with phils diagnosis that theres been no 'expansion measures' included to the fixings. ie some sort of flexible washer or plate?

The sub floor has expansion and lateral movement catered for but the actual bolt fixings are rigid, tight and no allowance for 'up and down movement', hence the structal stress.. those front stantions that are holding the platform up, tend to move ,up and down throughout the day. heat, wind, ground moisture all play a part.

thats the best i could come up with?

 

[Alan.P]

Come on then Jay, put us out of our misery lol

 

[Stewart]

I would also suggest the design of the railing fixing is wrong and shouldn't be able to put any pressure on the top of the tiles........

Daaaamn. I'm going to forget about this and I want to know what the crack is (no pun intended).

Somebody remind me when he tells us all? lol
