Peterhead Port – settlement stabilisation

Challenge

Settlement at operational port infrastructure in Peterhead threatened structural performance and required stabilisation without disrupting critical marine and logistical operations.

Solution

Geobear delivered targeted geopolymer injection to strengthen underlying soils and arrest settlement, restoring ground stability with minimal disruption to port activities.

Operational port environment

Works completed with minimal disruption

Settlement mitigated

Ground conditions stabilised

Non‑intrusive method

No excavation or shutdown required

Background

At Peterhead Port, ground settlement beneath key infrastructure raised concerns about long‑term serviceability and safety.

Given the live operational environment, any remediation strategy needed to maintain port functionality while addressing underlying soil instability.



Challenge

Traditional excavation or piling solutions would have caused significant disruption to port operations, increased costs and extended programme duration.

A rapid, low‑impact ground improvement method was required to restore support and prevent further settlement.

Solutions

Geobear implemented a precision geopolymer injection programme beneath the affected areas.

Through small injection points, expanding geopolymer was introduced into weak and voided soils. The material filled cavities, compacted loose ground and increased bearing capacity, arresting settlement without surface disturbance.

Real‑time monitoring ensured controlled lift and consistent performance throughout the works.

Results

Settlement was halted and ground stability restored without interrupting port operations.

The solution provided a fast, cost‑effective and lower‑carbon alternative to traditional ground remediation techniques.
