Slab Jacking

Is your house or building starting to look a little worse for wear on the outside? Or perhaps you’ve noticed from afar that it’s beginning to look a little lower than it should be? Your foundation may be compromised, and the building may be settling into the ground.

While this is certainly cause for concern, it is not causing for alarm – more than likely, your building isn’t going to fall over tomorrow! Here at Raise + Relevel, we can help,  using our slab jacking technology to raise and re-level an uneven or subsided building. Using this technique of concrete levelling will save you money, and time and ensure that your home or building remains intact for years to come.

What is slab jacking?

No matter where you live, you’ll see concrete forms somewhere, whether in a city or in the country. If you live in a house, there’s definitely concrete in that foundation. Over time, concrete can move and begin to sink – this is where slab jacking comes into play. Slab jacking is the process of lifting sunken concrete and relevelling it to its as-built condition.

Unlike the more traditional method of foundation repairs, which jacks up the entire building and then fills beneath it, slab jacking is a more cost-effective and less time-consuming process. It is achieved by drilling holes in settled slabs or footings and injecting through the holes with polyurethane resin. Eventually, when enough polyurethane resin is injected beneath the footings, the force from this specialised resin will create enough pressure to raise and relevel the structure back into its original position.

What does slab jacking achieve?

One of the main things that concrete slab jacking achieves is that it restores subsided structures back to level. Slab jacking is the most convenient concrete levelling solution – because we use an expanding resin to improve the strength and bearing capacity of the foundations – the structural polyurethane resin that we use sets in seconds and gives us a high level of control over this structure with lift and areas that are being treated, rather than traditional concrete underpinning, which can take days. Slab jacking in this fashion can be compared with keyhole surgery, a quick and relatively easy method of re-levelling your concrete footing.

What causes the need for slab jacking?

Concrete moves over time for a wide variety of reasons – no matter how solid you might think your foundation is, chances are, it may need to be slab jacked at some point during its lifetime. This can be due to the structure being poorly constructed or the foundations being improperly compacted, resulting in settlement.

It can also be due to changes in the environment, climate and indeed soil. Say you’re in a part of the country that is built on reactive clay soil types which are notorious for seasonal volumetric changes. These shrink-swell cycles can often impact the structure and manifest as cracks or damage.

If you’re purchasing or have purchased an older home that shows symptoms of subsidence, you’re going to want to get your foundation inspected by Raise and Relevel. This will ensure that whatever was originally constructed is still good to go before you start doing any other renovation work.

What signs are there that you’ll need slab jacking?

There are several key signs to look for when inspecting your foundation. For instance, if you start seeing cracked walls – that’s a big sign that something is wrong with your foundation. Another thing to look out for is uneven flooring on the ground floor. You can also perform a visual inspection of your crawlspace to ensure that there’s no excessive moisture or separated piers. Other than that, check your doorways and windows to see if they’re jamming, that’s another tell-tale sign that something is wrong with your foundation – your doorways should not be crooked!

Other things you need to know about slab jacking

One of the many reasons homeowners turn to slab jacking is that it’s a more cost-effective way to re-level your home. With decades of professional experience, we’ll work with the existing footings, thereby greatly reducing your cost, by using expanding resin to return the existing slab back into its original position. Because we’re working with the original concrete slab – this means we don’t have to pour a new one, nor spend the labour getting the old one out of the way.

Also, because we use such precise technology, we don’t need to disturb any of the original landscaping around the property – no need to tear up your lawn with big, heavy equipment – our resin pumping rig can fit in a driveway just fine! We use a portable pump to inject the resin into the holes we drill, so the process is as minimally invasive as possible.
