At Adelaide Underpinning Group, we understand the complexities of sinking concrete within and around the home. Our skilled team is proficient in spotting these hidden risks that typically indicate more severe structural concerns resulting from soil movement or undue pressure.

We use a specialised process called slab jacking. This approach elevates and stabilises these compromised slabs, thwarting any additional sinking.

What Causes Concrete to Sink?

These are the main causes of sinking concrete:

Insufficient Soil Compaction

When soil isn’t packed well during construction, it can cause concrete to sink. This is because improper soil packing leaves too much air in the ground, making it weak and incapable of supporting the weight of concrete.

Stormwater Damage

If stormwater isn’t effectively managed, it can direct water toward your home’s foundation instead of away from it. Water that seeps into the ground and under your concrete can erode the soil. As a result, the foundation becomes unstable, and the concrete can start sinking.

Ground Vibrations

When there’s lots of ground shaking caused by nearby construction, heavy traffic, or even airplanes, concrete can start to sink. These powerful vibrations shake up the soil and fill it with air, which makes it less stable.

Poor Drainage

Bad drainage can also lead to sinking concrete. Water from burst, cracked, or improperly connected pipes in your home can accumulate under your concrete slabs and floors. This can over-saturate the soil, making it weak and unstable.

How Can I Tell If I Have Sinking Concrete?

These are the primary signs of sinking concrete:

Slanted Floors

A noticeable indication of a sinking concrete floor is when it’s slanted. If one part of your concrete floor seems lower than the rest, it can become a potential tripping risk, as it feels like you’re walking on irregular stairs.

Bowing Floors

A concrete floor that curves inward, making the middle part look lower than the sides, suggests that the floor is sinking. If you see things rolling toward the middle of the room, it’s probably because of a sagging floor, a sign of sinking concrete.

Skirting Board Gaps

Sinking concrete can make your baseboards separate from the bottom of your indoor walls, creating visible spaces. If your baseboards are not perfectly aligned with your walls, your concrete floor will likely sink.

Why You Should Address Sinking Concrete

You need to address sinking concrete because it will seriously threaten your home’s stability and safety. Without attention, it can lead to significant issues, like creating spots where you could trip or causing your doors to not line up properly.

On top of that, if you’re seeing spaces under your baseboards, this might be a small sign of a much larger problem with your home’s structure.

It’s essential to fix sinking concrete as soon as possible. This can help avoid accidents and save you from a costly and extensive repair job.

Our Slab Lifting Solutions

At Adelaide Underpinning Group, we help repair sinking concrete floors. We use a method called “slab jacking” to raise and level your concrete. This makes your home more stable and helps prevent structural issues like cracks in your walls and ceilings or doors that won’t open and close properly.

We use various techniques to prevent further sinking, including mass concrete underpinning, steel pile underpinning, and cement grout underpinning. Our advanced tools and equipment ensure that your concrete floors are flat and secure, which is key to keeping your home safe and sound.
