2. Balcony Waterproof Membranes
Why Do They Fail?

3. Obviously membrane failure is
caused by a variety of reasons
However……
I have been in the construction game for over 30
years, either as a registered building practitioner
myself or the owner of F.E.W Waterproofing.
Having construction knowledge does give me an
advantage when trying to work out the structural
causes of water ingress.

4. Recent projects have highlighted an interesting
cause for waterproof membrane failure.

5. Balcony floors designed with
minimal falls
• Construction methods are always changing and
adapting.
• I have recently noticed, either for reasons of
design and/or cost considerations, subtle changes
which have a direct impact on the success or
otherwise of waterproofing membranes.

6. Many balcony floors are constructed with minimal
falls; particularly evidenced in multi-level
apartments.

7. Correct waterproof membrane is imperative with
structures designed with minimal falls.
The membrane must be capable of “ponding” water
and the application must proceed with meticulous
preparation to ensure detailing is installed correctly.

8. Over the years we have become advocates of
Liquid Rubber waterproof membranes - we have
experienced great results where other products
have failed.

9. F.E.W Waterproofing is an
independent company
We choose the product based on our knowledge,
experience and the requirements of the individual
waterproofing project.
Liquid Rubber is our waterproof membrane of
choice with minimal fall balconies, roof tops,
retaining walls, below ground structures.

10. Liquid Rubber provides a seamless environmentally
safe and highly flexible membrane that will “hold”
and contain water without breaking down - not all
products are capable of this.

11. The adhesive must be suitable to allow the field of
tiles to expand and contract during cyclic temperature
changes.

12. It is imperative to insert balcony floor expansion joints where
the balcony floor abuts the vertical wall.
This is particularly important for large balconies; expansion
joints break up the field and allow the tiles to expand and
contract.

13. Insufficient expansion joints can have a disastrous effect on the
success of a waterproof membrane.
If tiles are forced up, the membrane underneath will be
damaged – and guess what - WATER LEAKS!

14. Leaking structures are a builder’s
nightmare and major cause of
clients call back.
• NB: Don’t let the waterproof membrane be
damaged by subsequent trades – a constant
on-site problem.
• NB: Water test the membrane BEFORE tiling –
ensure the membrane is water tight.

15. Of course the best way
to avoid these nightmares is
to have your Waterproofing
installed correctly the First Time.
