Keller is committed to delivering its solutions in a socially and environmentally conscious manner.

Over recent years reporting processes have improved and performance is generally encouraging.

The overall number of environmental incidents remained in line with those reported the previous year, with most incidents being minor hydraulic leaks. We have therefore been rolling out our improved equipment inspection process, using our site software prior to each shift commencing, in an effort to reduce the number of minor spills.

We continue to work on our preventative maintenance programmes to ensure that we address any issues before the event occurs. In addition, we ensure that secondary containment is in place for stored equipment and materials. We continually seek to improve our processes on site, specifically around job planning, to ensure that we identify, mitigate and control our risks and minimise our environmental impact. More details can be found in our biodiversity policy.

Whilst as subcontractors we have limited control on biodiversity on site, multiple business units continue to engage with local organisations and wildlife trusts to promote local biodiversity. Nonetheless, for our own operations on specific projects, we make use of dust suppression and baffling to minimise the impact of dust and noise on the local environment. We also typically use local material suppliers to support local businesses, reduce transport distances and reduce congestion around our sites. We are engaging with our trade associations to highlight upcoming legislation and best practices for the geotechnical sector.

Case study

Keller brings expertise to hospital project

Combining a range of geotechnical products and environmental innovation, Keller is helping create a new future for Norway’s leading cancer hospital.

Keller tackling pollution at Radiumhospitalet

The Radiumhospitalet in Oslo is undergoing a major transformation, replacing outdated buildings with a state-of-the-art treatment centre. Keller’s foundation solution combined bored piles with a jet grout seal, and anchors.

A back-flow treatment plant for jet grouting was also included. This filters the water in the spoil, which can then be reused, reducing the amount of spoil sent to landfill. To avoid overconsumption of the concrete caused by the soft clays, the ground was pre-stabilised using deep soil mixing.

Noise reduction was a priority on the live hospital site. Keller mitigated this through reverse circulation drilling. This involved water-powered, rather than air-powered, machinery, which is quieter, and also reduces vibration and the risk of settlement.

The government was looking for a quality solution, but also one that considered the environment. We were able to design a complete solution that reduced risk, noise and waste, and worked in difficult  and low-headroom areas.”
