Soil Stabilisation

Stable soil is essential for the foundation of any build. With our industry expertise, machinery and skill we are able to help you attain the tensile strength your soil requires to allow for a successful build.

What Is Soil Stabilisation?

Soil stabilisation is where soils are altered to enhance their physical properties.

Ground stabilisation is a process of raising your property up to its original position by injecting fluid under your support to re-level your structure.

Stabilisation can increase the shear strength of a soil and/or control the shrink-swell properties of the soil, thus improving the load bearing capacity of sub-grade to support pavements and foundations.

Why Is Soil Stabilisation Needed?

It is not uncommon for a property’s soil or foundation to experience some softening overtime and require some soil stabilisation.

When soil softens it renders the foundation of a build less stable and structurally sound which not only hold the ability to affect the value of the property but may likewise cause some significant safety concerns.

Ground stabilisation thus aims at improving soil strength by changing the current loose sub soil back to its original cohesive and stable medium able to better perform and intended and required.

What Does Soil Stabilisation Look Like?

The need for soil stabilisation in regards to the foundation of a build can be identified via the sloping of or cracks in joints, bricks, doors, window frames, walls, ceilings and floors of the build.

A further sign of subsidence is the general sloping of the property to one side.

In addition, it is worth knowing that cracks caused by subsidence are likely to be diagonal and wider at the top than the bottom, wider than 3mm (width of a 10p coin), visible from both the outside and inside of a wall and located close to a window or door.

However, if concerned over possible subsidence it is important to get in contact with industry professionals such as us seeing that the identification of subsidence is not always straight forward.

How Is Soil Stabilisation Conducted?

If you are concerned over your soil and suspect it has experienced softening over time, the first thing to do is consult a surveyor.

You will need industry professionals such as ourselves to be able to assess the situation and provide a comprehensive report on the condition of your soil.

If the need for ground stabilisation is identified by your surveyors, the remedial work necessary will depend on the extent to which your soil has softened.

If you structure has sunk to quite an extent, drilling keyhole-sized entry points through your foundation for injection tubes may be necessary.

We would then inject non-toxic inert cement and resign grouts as a means to re-level your soil.

Each soil stabilisation process is different, however, thus for further information unique to your situation please feel free to get in contact with one of our industry specialists who are able to provide you with a free consultation and quotation today!

What Causes The Need For Soil Stabilisation?

There are many factors which end up rendering soil unstable, some of which can be found below:

Erosion – Poor drainage, improperly placed downspouts, leaking drain pipes, and broken water lines are common culprits.

Poor compaction – When backfilling on a jobsite, the contractor is supposed to compact the backfill by driving over it with heavy equipment.

However, this isn’t always done properly for one reason or another.

Freeze/thaw – Processes of freezing and thawing essentially accelerate erosion processes. Cold weather freezes moisture trapped in tiny cracks.

When this water freezes, it expands, subsequently pushing on the rocks and breaking them into smaller pieces.

As processes of freezing and thawing continue, rock and sediment are continually broken down.

Biological decay – Construction trash pits, buried trees, and other biodegradable materials all break down.

Sometimes structures are built over these areas.

In all, there is a vast range of different reasons as to why soil may become unstable over time which are unique to each soil and its environment.

How Can Polymer Foam Help?

Using polymer foam as a means to stabilise soil holds a number of benefits which can be found below: Reinforcing eroded areas – Polymer foam displaces water and cures into a solid mass reversing the erosion process. Permeating soil – AP Soil 600 foam permeates loose soil to create a strong substrate. Filling voids caused by decay – Polymer foam fills voids before it cures, making it a great solution for instances of biological decay. AP Soil 600, AP Lift 430 and AP Lift 475 are approved for contact with drinking water (certified to NSF 61-5). That means they can be used anywhere without having an adverse effect on water quality. Having our core products rigorously tested for environmental compatibility is a key component of our commitment to assuring “painless procedures” for customers. Lasting soil stabilization. Alchemy-Spetec structural foams are stronger than crystalline bedrock.

What Are The Benefits Of Soil Stabilisation?

Soil stabilisation is a repair method able to provide a strong working platform to the foundation of either an already built property or to one which is yet to be built. Stabilising your foundation is an extremely beneficial process given that it holds the ability to attain an abundance of advantages. When soil increases in tensile strength, it becomes much more appropriate for construction and allows a build to be built with much higher structural integrity. Not only will this increase the quality of the property, but will prevent the need for any major repairs to be conducted on the foundation in the future. A strong foundation likewise ensures that your property does not devalue over time. Unstable soil is also a significant health hazard and one which will definitely need to be addressed over time. In all, ground stabilisation allows your soil to become much more workable and increases the probability that you won’t have to undergo further costly, time consuming and substantial foundational repairs in the future.
