Ground, Earth and Soil Stabilisation
Having strong foundations under your home or business should not be underestimated—foundations collapsing can cause catastrophic damage. Being proactive can prevent this from happening. If you’ve got problems with sinking foundations, you should act as quickly as possible to make sure that your building remains stable and safe.
This is where Geobear comes in. Our team of specialist ground engineering contractors are experts in ground, earth and soil stabilisation and can deal with whatever ground type or foundation you’ve got. Whatever the soil type – be it clay, sand or any other variety – Geobear can help.
What is Soil Stabilisation?
Ground stabilisation or soil stabilisation is the process of making changes to the soil to improve its ability to bear weight and to increase its tensile strength. This creates a more reliable basis for building and construction works and can remedy existing issues with earth and subsoils that are causing problems.
There are various different methods of soil or ground stabilisation available. The most modern and effective type, used by Geobear, is geopolymer resin injection.
Geo-Polymer vs Older Methods
We believe that our method of stabilisation is the future when it comes to underpinning. Here’s why:
Lime stabilisation is where a binder element such as quicklime is asses to the soil. Not only is this a lot more disruptive and time-consuming than the quick resin injection process, it is also a pre-construction measure and cannot be used to stabilise the ground under existing buildings.
Chemical stabilisation again involves mixing the existing soil with substances to change its properties. Again this is carried out prior to construction. There are many criticisms that chemical stabilisation is not very environmentally friendly.
Cement under-pinning is old news – it’s a much slower process than resin injection and often costs more money than our fast, non-intrusive resin injection method. Concrete requires a massive amount of excavation for it to work. You need to remove a load of the soil around and under the existing foundation in order to fill more space with concrete. This means that it takes a long time to finish. Resin, on the other hand, requires little or no excavation – it is injected via small holes bored into the soil all around the foundation.
Stabilisation Through Resin Injection
Here at Geobear, we use an innovative resin injection method for stabilising buildings. Stabilisation is the first port of call for making your foundations secure and preventing them from sinking any further.
Our injection solution for ground, earth and soil stabilisation is a controlled process whereby geo-polymer resin is injected into the ground to prevent movement, without raising any of the existing slabs or structures.
The stabilisation process uses resin injected at points beneath a slab, pad or foundation, where it expands to fill any voids in underlying soils and compact any existing made ground. This high-precision technique is used under properties, roads, railways, airports and ports.
How the Ground Stabilisation Process Works
Every single resin injection stabilisation project we do is given unique treatment. We choose a specific slow-expanding resin for each job, depending on the ground type and foundation.
To achieve precision control, we set up multiple monitoring systems to ensure no more than 250 microns of resistance on the slab or floor. Fundamentally, this precision control measures a lateral lift far too small for the eye to see that indicates that the ground beneath has been stabilised and your building is now safe.
The wet resin is absorbed by the surrounding soil and the two bind together. The resin then expands as it dries and then fills the void. This is a much faster process than the concrete underpinning.
If soil subsidence is the main cause of your foundation woes, then resin injection is the far superior option, because of the way it binds with the soil. Concrete only adds mass to the existing foundation.
