To some, balcony deck waterproofing would be a no brainer. However, most building contractors consider it unnecessary and do not install it in order to keep the cost of the construction project down. However, balcony safety is a major concern especially when it comes to falling concrete. There are major consequences for balcony neglect.
Balcony waterproofing is important if you want to avoid severe structural damage to your balcony, the room below and the overall working condition of the balcony slab. We have seen situations whereby clients bought a house with a balcony which they did not know had not been waterproofed. As a result, the balcony structure deteriorated causing it to no longer be safe to walk on and became a huge safety hazard.
Tiled Balcony Waterproofing
Tile and grout are porous materials. Tile balcony leaks are the more common type of balcony structure to leak due to the water being able to seep through the tiles and grout and into the membranes below. A balcony waterproofing system needs to be chosen to best suit the current situation of the balcony or terrace. Paying careful attention to specific details on the balcony and the structure overall.
First Step During A Balcony Inspection
The first step during a balcony evaluation is to inspect the current condition of the existing flooring (the visible layer). Some easy to see causes of a balcony leak would include:
- Cracked Grout.
- Mould Growth Between Tiles.
- Mould Growth At Wall/Floor Junction.
- Tiles Pulling Away From Side Edge.
- Loose Tiles.
- Cracked Downpipes.
- Ponding Water (No Slope).
- No Balcony Threshold (The house floor level should always be higher than the balcony. You should step down slightly when walking onto your balcony).
Over-Tile Balcony Waterproofing Sealants
Although there are over-tile waterproofing systems, we avoid them as much as possible. Yes, they are sometimes cheaper than other waterproofing systems. However, tile sealants and coatings usually wear out a lot faster. Some areas faster than others depending on the amount of traffic the balcony receives. Even the best tile sealant products on the market will eventually wear down due to weather, aging, and general stress. Therefore, the waterproofing system presented to you by the waterproofing contractor needs to suit your balcony and its current state.
We do prefer under-tile waterproofing systems. This system does include hacking up the old tiles and comes with a 5 year guarantee. However, upon inspection of the balcony our waterproofing technician will advise which system will be best for you.
