Hardwearing Waterproofing for Concrete Balcony that is used

[safara]

On the ask for some advice.

The place we are renovating has a Balcony area. It is the roof for a section of rooms below it. It measures about 5 x 6 meters, but can check.

It is a concrete roof and solid. It has little parapet walls rising about 10 inches, so effectively a tub. With a single drain out in the middle of the end to the back. One side and part of the other butts up against the wall for the rest of the building. There has been leaks at this join in the past, but for the moment it is sealed with some roof sealer stuff.

It looks like it is currently covered in a fiberglass/bitumen combo - see photos.

What I would like to know is what would be a good thing to brush/paint/cover this with, rising up the sides to form a hard wearing waterproof cover for this. This area is used with tables and chairs etc etc.

SBR the whole thing? That tough enough? Acrypol, but will that handle the traffic? What's the answer

You do not say if its leaking,but I would either deck it or light weight slabs on roof support pads if it was not leaking.

Hi Dilly

It does leak on occasion at the edges - but these have been masticked up. There are little patches of it that seem to have holes or thin bits.

Was after what wonder substance I can coat it with to make sure and keep the thing watertight LOL

 

[dilly]

Any coating you buy will only be temporary,you best get a local flat roofer to have a look to see what the build up is,as it is a baloney what ever you use needs to be hard wearing eg fibreglass.

Cheers Dilly - Fiberglass has been mentioned - just was not sure on the durability of it with tables and chairs on it etc.

It needs Asphalt or felt with promenade tiles on, as will any membrane to protect it.

Alternatively, Triflex. Designed for exactly that purpose, but you need to be an approved installer.

Liquid plastics would be another option.

Liquid plastics would be another option.

Will need to be Balcons system, again, approved installer.
