Teretek® Resin Injection

Understanding the Benefits of Resin Injection

Resin injection is a modern technique gaining popularity in the engineering industry. It’s used for underpinning and stabilising foundations, offering many benefits.

This method involves injecting a resin material into the ground. The resin solidifies and strengthens the existing soil, enhancing its load-bearing capacity.

Resin injection is less invasive than traditional underpinning methods. It’s quick, often completed within hours or a few days, minimising disruption to the property.

Moreover, it’s a cost-effective solution which makes resin injection a preferred choice for many.

This article aims to provide comprehensive information on resin injection. It will help homeowners, property managers, and engineering professionals understand when and why to choose this method for their projects.

Let’s explore the advantages of resin injection, including its cost-effectiveness and its benefits compared to traditional methods.

What is Resin Injection?

Resin injection is a technique for providing ground improvement and level correction.

It involves injecting a specialised resin into the ground. This resin expands and solidifies upon injection. The process strengthens the soil, providing ground improvement and level correction.

The technology is used to underpin foundations and correct structural issues. It addresses problems like soil subsidence, sinking foundations and uneven surfaces.

One major advantage is its adaptability to different soil types, allowing resin injection to be effective in applications where other methods may fail.

The technology is also useful for filling voids in the soil, further enhancing stability and reducing risks of future subsidence.

Teretek® Resin Injection

How Resin Injection Works

Resin injection works by improving the load-bearing capacity of the soil. A resin material is injected under pressure into the ground.

Once injected, the resin undergoes a controlled expansion process. This helps fill voids and strengthen weak soil layers.

The resin’s expansion applies a gentle lifting force. This can help adjust any foundation settlement.

Resin injection is precise, allowing for targeted application. It can focus on specific areas that require ground improvement and level correction.

It’s a versatile technique suitable for both commercial and residential buildings and structures. Its adaptability sets it apart from other underpinning methods.

Unique Features of Teretek® Resin Injection

Precision Re-Levelling

Teretek results in accurate lift or ground improvement beneath existing structures.

Minimally Invasive Process

Teretek only requires small holes for the resin injection, resulting in a low-impact solution for the structure.

Quick and Efficient

Teretek provides a fast solution, minimising downtime and business interruption.

Environmentally Inert

Teretek resins are water-resistant, chemically stable, and do not leach.

Advantages of Resin Injection Underpinning
Fast & Clean

Our technologies have fast curing times and treated areas can be used immediately or without the delays compared to traditional repair methods.

Environmentally Inert

Our technologies use an inert material that is non-toxic and does not leach into the environment or affect the treated area.

Non-Invasive

Our solutions are of surgical nature compared to traditional methods.

Cost-Effective

Compared to traditional methods, our solutions are more cost-effective, with minimal disruption to the area.

Resin Injection

Common Misconceptions and FAQs

Many myths surround resin injection. Some believe it’s only for emergencies, but it’s also preventive. Others think it’s expensive compared to traditional methods. Yet, considering long-term benefits, it can be more economical. A frequent misconception is that resin injection cannot handle heavy loads. In reality, cured resin is very strong. Some question if the process is harmful to the environment. Actually, it’s environmentally inert with no effect on the environment.

Is resin injection suitable for all soil types?

Yes, it works well in diverse soil conditions.

Can it be used in residential projects?

Yes, resin injection is suitable for residential, commercial, infrastructure and mining structures. 

How long does the process take?

Typically, projects are completed in hours or a few days; however, it depends on the size of the project. 

Is there significant excavation involved?

No, it’s a non-invasive method with little disruption to the treatment and surrounding areas. 

Does the resin last long?

Yes, Mainmark provides a 50 year product warranty on the Teretek resin – providing you with peace of mind.
