We are committed to delivering our solutions in a socially and environmentally conscious manner.

Improving our impact on communities

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

We have rolled out our improved equipment inspection process, prior to each shift starting, 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.

Whilst as subcontractors we have minimal control on biodiversity on site, multiple business units continue to engage with wildlife trusts to promote local biodiversity.

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The Radiumhospitalet in Oslo is undergoing a major transformation, replacing outdated buildings with a state-of-the-art treatment centre.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.”
