Balcony Decking

macronot

Hi All,
Just moved into a new apt. and it has a Balcony. The balcony has what looks like a tarmac seal on the floor. The surveryor suggested that i should put some decking down to stop this membrain from being punctured. I have been looking around for some decking but i am not sure exactly what i should be looking for - I did see some square wooden treated decking 600cm sq. Would this be suitable? The Balcony is approx 5' by 6'.

Any ideas?

Thanks.

Victor

It's likely to be pure asphalt, commonly used, however it tends to expand / contract depending on temperature and direct sunlight (its black).

What is needed is something to remove it from the direct sunlight and prevent mechanical damage. Sometimes a (special) reflective paint is used (not suitable for working surfaces), other times, gravel (round, not pointed) or paving slabs. Just make sure the roof can also drain.

I suggest first off you check against the show house / specification as to whether the builder should have provided something. Secondly, check your residents agreement as to what you are allowed alter (the deck may constitute and alteration). Is your balcony someone else's roof (this may put obligations on you to maintain his roof, which is pushing things).

You could use this, but make sure the weight is well spread (to avoid pressure points on the asphalt), that the gaps (between individual boards and between sections) are no more than about 5mm (to stop things falling through / stiletto shoes, etc.). Make sure the units are heavy enough that they won't lift in even the heaviest wind. Allow for drainage. What guarantee is there against warping (trip hazard). What do you do at the edges where you have a 100 / 200 / 300mm gap (gravel is a possibility)?

More decking comes in lengths which you cut to size, which are then screwed to cross bearers or a similar size at about 300mm centres.

Thanks Victor,
