Ground Investigation Reports for Mezzanine Floors
Ensure a Solid Foundation Before You Build
Before a mezzanine floor can be safely designed and installed, it’s crucial to understand what lies beneath. A Ground Investigation Report (GIR) is a key part of the pre-construction process, helping to identify the physical properties of the ground and assess its suitability to support a new mezzanine structure.
At Hi-Level Mezzanines, we work closely with geotechnical engineers to ensure your site is properly evaluated before any steelwork is erected. This proactive step helps avoid costly complications down the line and ensures your mezzanine is structurally sound from the ground up.
Why Ground Investigations Matter for Mezzanines
Mezzanine floors, while internal, rely heavily on the strength and stability of the ground slab and subsoil beneath them. If the ground is unsuitable – whether due to poor load-bearing capacity, excessive moisture content, or reactive clay – it can cause settlement, cracking, or failure in the supporting structure.
As explained in our blog “All You Need to Know About Ground Slabs for Mezzanines”, the ground slab is a critical component of mezzanine performance. Without a full understanding of what supports it, your project could face delays, increased costs, or even structural risks.
What Does a Ground Investigation Include?
A typical investigation for a mezzanine installation involves:
- Drilling boreholes using geotechnical rigs to depths of up to 18 metres.
- Collecting soil samples – both disturbed and undisturbed – to assess composition and moisture.
- Testing for characteristics such as shrink/swell potential, bearing capacity, and settlement risk.
- Evaluating subsoil interaction with potential foundations or load points of the mezzanine.
This analysis enables engineers to make informed design decisions – whether it’s specifying pad foundations, spreading loads differently, or reinforcing the existing slab.
Prevent Problems Before They Begin
Soils with high clay content may swell or shrink depending on moisture levels, leading to ground movement that compromises structural stability. Similarly, soft or poorly compacted soils may not support mezzanine columns without additional reinforcement. These risks are preventable if identified early.
As discussed in our article “Going Underground: Why Your Mezzanine Floor Needs Deep Thinking”, these investigations aren’t just for large buildings – they’re just as important for internal structures like mezzanines, especially in warehouses or distribution centres with high point loads.
