When is a site investigation needed?

Our initial consultation with you, which can often be done virtually, gives us a wealth of information.

However, if we suspect a more complex issue, such as deep-seated clay shrinkage or variable ground conditions, we will recommend a full geotechnical investigation.

This step is necessary when we need precise data that can only be gathered by physically sampling the soil.

It’s how we move from a professional assessment to an undeniable, scientific diagnosis.

What does a Geobear site investigation involve?

Our investigations are designed to be highly targeted and minimally disruptive. The primary method we use is borehole soil testing.

Using compact and specialised equipment, our engineers will perform Dynamic Sampling (often called 'Window' or 'Windowless Sampling'). This involves driving a hollow tube deep into the ground to extract an undisturbed core sample of the soil. This sample provides a clear, layered record of the ground beneath your home.

These core samples are then carefully logged and sent to an independent, UKAS-accredited laboratory. Here, they undergo a suite of laboratory testing to determine their precise geotechnical properties.

What the scientific data tells us

The soil investigation report we receive from the lab provides our in-house engineers with the hard data they need. We can determine critical geotechnical parameters, including:

Soil Strata

The type, thickness, and depth of each different soil layer.Plasticity Index: A key measure of how much clay soil will shrink or swell with changes in moisture

Moisture Content

The exact amount of water in the soil at various depths.

Sulphate and pH Levels

The chemical makeup of the soil and groundwater.

Site investigation frequently asked questions

Most standard site investigations are completed within a few hours. We work efficiently to minimize any disruption to your day, and you will be kept informed throughout the process.

While you don't need to be present for the entire duration, it is helpful if you are there at the beginning to meet the engineer and provide access to the property. We can then proceed with the external survey work.

Following the investigation, you will receive a comprehensive report that details the findings. This includes an analysis of the ground conditions, the likely cause of any issues, and a clear, jargon-free recommendation for the best way forward.

Yes, there is a fee for a professional site investigation. This covers the time and expertise of our specialist engineers and the detailed analysis required to give you a definitive answer about your property. This initial investment is the most reliable way to understand the problem and avoid more costly, unnecessary work in the future.
