St George Towers And Riverfront Blocks

Leaking Shower Repairs Georges River

The high rise core around Hurstville station has reached its first real maintenance cycle. It shows.

Buildings put up through the 2000s and 2010s around the station and Forest Road are now old enough that the original silicone has hardened and the floor grout has shrunk. Meanwhile the streets running down to the river at Blakehurst, Connells Point and Oatley are all sloping blocks with bathrooms over undercroft garages. One council area, two very different sets of problems.

Leak detection leads here, because in a tower the cost of guessing is somebody else’s ceiling. Each service links through to its own page.

River blocks and station towers

One council area, two building stories

The land here falls away toward the water, which is why so many homes at Blakehurst, Connells Point, Kyle Bay and Oatley have a garage tucked underneath and a bathroom sitting directly over it. When a shower in one of those leaks, the evidence turns up on the garage ceiling rather than anywhere useful.

Then there is the other Georges River, the high rise core around Hurstville station and Forest Road. Ensuites and main bathrooms on concrete slabs, large format tiling, and construction silicone that was applied at handover and is now well past its working life.

Between the two sit Penshurst, Mortdale and Beverly Hills, mostly interwar and post-war brick where the original shower bed frequently has no membrane at all. Three stocks, three approaches, one crew who knows which is which before they arrive.

What our inspection covers here

Timed flood test on the base with the waste plugged

Moisture readings taken from the dry side of every shared wall

Confirmation from the garage or apartment below where access allows

Waste flange seal checked, a frequent failure in slab construction

Grout tested for shrinkage and hollow sections

Screen track, weep holes and hob junction inspected

A written finding that names the failed element, not just the symptom

The sequence we follow

1

Tell us the constraints

Occupied hours, permitted noise windows, who controls access. We plan around them.

2

Building access sorted

Dock, lift and hours booked in advance where the building requires it.

3

On site testing

Flood test, moisture map, thermal. Confirmed from below where we can get in.

4

The finding in writing

One page, one fixed figure, forwardable to whoever signs off.

5

Repair, then confirm

Work completed, tested again, and a clear answer on when to use it.

One recess, ten days apart

What actually changes

A shower that has been leaking quietly for years looks unremarkable. That is precisely the problem with it.

What the phone calls sound like

Questions worth answering properly

Carefully and in the right order. There is no subfloor to get under, so everything is read from above and from the apartment below, which makes accurate testing more important than anywhere else. Once the source is confirmed, most tower leaks turn out to be at the silicone joints or in shrunken floor grout rather than the membrane, and both are repaired with the tiles left in place. Access is the other half of the job, and we book the dock and the lift before we come.

It depends what is below. Over a slab, water tracks along the topping and comes out in the ceiling of whatever is downhill, often not the room directly under the shower. Over an undercroft garage, which is common on the sloping blocks down toward the river, it stains and eventually sags the ceiling lining. Over timber, it reaches the joists and that becomes a structural conversation rather than a tiling one.

No, and assuming it does is how people end up paying for a strip out they never needed. Water gets in through failed silicone, cracked or shrunken grout, a poorly sealed waste flange or a corroded screen track long before the membrane is the culprit. A flood test tells you which. If the base holds water, the membrane is doing its job and the problem is above it.

Sooner than most people do, but there is no need to panic. Water damage compounds quietly, so a small stain that has been there six months has usually been wet for a lot longer. If a neighbour below is reporting water, stop using the shower and get it tested that week. If it is a bit of dark grout and no damp anywhere else, you have time to get it looked at properly rather than accepting the first quote.

Neighbour reporting water, or a stain on the garage ceiling? Get the cause confirmed first.
