Construction group's quick-setting material saves UK economy £35m



Kier Highways – the road maintenance arm of Kier Group – has saved the UK economy £35m on a single project through the use of a new, rapid-setting material.

The innovative substance – which reaches design strength in 18 hours instead of the traditional three days – enabled Kier to implement a different traffic management model and prevent a lane closure on an M6 repair scheme.

This lane closure would have caused an average 45-minute additional delay from Monday to Thursday and 55 minutes on a Friday, equating to a £35m impact on GDP over seven weeks.

“The material cures quicker and gains density as it dries meaning that repair crews can work faster to carry out repairs without having to wait as long for it to dry,” said Jessica Kenny, project manager at Highways England.

“Safety is always our number one priority and these repairs were vital in helping us to protect this busy stretch of road for years to come.”

In total, 38 repair specialists worked 9,723 hours overnight and weekends to fix damaged concrete and waterproofing material underneath the road.

As part of the scheme, 130m of expansion joints were also installed to provide additional strength and flexibility to the carriageway.

“In close collaboration with our clients and supply chain, we’ve intentionally focused on pioneering new ways of doing things,” added Dave Wright, executive director at Kier Highways.

“The use of this new material is testament to having a collaborative client in Highways England, and offers tremendous scope for reducing disruption nationwide.

“Having extensively trialled the product, we were trusted to use this new method and it has yielded excellent results, both in the efficiencies and savings, and in the quality of the solution.”
