Fault Zones and Voids

Global experts at finding faults

Accurate mapping of geological faults, voids and highly weathered zones is critical for successful foundation design – and Zetica’s unobtrusive surveys provide the detailed ground profile you need to design and build with confidence.

We can help characterise overburden soil stiffness, as well as mapping faulting or large voids in the underlying geology that can be a source of relative movement, preferential groundwater flowpaths and differential settlement.

Our surveys can also help you understand the risk of soil liquefaction in earthquake-prone areas – providing a more thorough understanding of ground conditions than can be achieved by traditional, intrusive techniques.

That’s why we’re trusted by large consultancies around the world to inform the design of major structures – often on the most complex and challenging geology.
