At Sydney Restumping & Underpinning, we know how tricky it can be to deal with sinking concrete in your home. Our skilled team spots these hidden troubles, usually tucked away inside the house, that hint at more significant foundation problems caused by ground movements and too much pressure.

Using our straightforward concrete levelling method, often called slab jacking, we raise and secure those dropped slabs to stop them from sinking further. Ring us today for a free check-up to see how stable your home’s concrete is.

What Causes Concrete to Sink?

Concrete can sink due to the following reasons:

Poor Ground Preparation

Not preparing the soil well during building work can lead to concrete dropping. If the ground isn’t compacted properly, it has too much air in it, making it wobbly and not firm enough to hold up concrete.

Stormwater Issues

When it pours and your drains can’t cope, water might flow toward your home’s base instead of away. This water seeps into the ground below your concrete, washing the soil away. Over time, this makes the ground shaky, and your concrete starts to sink.

Ground Vibrations

If there’s a lot of movement nearby, like building work, big lorries going past, or planes overhead, the ground can shake a lot. This rattling can loosen and mix air into the soil, which makes it less solid.

Drainage Problems

Bad drainage can also cause your concrete to drop. Water from broken, split, or unlinked pipes in your home can gather under your concrete. As the ground soaks up this water, it becomes mushy and won’t support the concrete properly.

How to Tell If You Have Sinking Concrete

Here are the signs indicating your property has sinking concrete:

Tilted Floors

A clear giveaway of sinking concrete is when your floor leans to one side. If part of your concrete floor seems lower, it can be a tripping risk, making it feel like you’re on a wonky path.

Dipping Floors

If your concrete floor seems to curve inwards, dipping down in the middle, it’s a sign of sinking. When things like balls roll toward the room’s centre without a push, it’s probably due to a dipping floor. This curve can eventually lead to stuck internal doors because the shape of the room changes.

Gaps Near the Skirting

When concrete sinks, your skirting boards might no longer sit snugly against your walls. If you see spaces between them and the walls, it suggests your concrete floor might be sinking.

Why Address Sinking Concrete

Overlooking sinking concrete can quickly jeopardise the safety and stability of your home. If left unchecked, it can lead to serious issues, from trip hazards to doors that won’t close properly.

Furthermore, those noticeable gaps beneath skirting boards might just be a small sign of a much bigger structural issue.

It’s vital to tackle sinking concrete straight away to avoid potential harm and save yourself from a costly, major repair job later on.
