A41 Stabilisation Works in Progress

(January 27, 2021)

Geobear has started a two-week programme of work to stabilise a section of the A41 in Aylesbury. 

Transport for Buckinghamshire appointed Geobear to carry out work which will stabilise rocking slabs down a 500-metre section of the Tring Road.  The busy route has been subject to many years of heavy goods vehicles travelling on the road. The increase in axle loads and the frequency of traffic has meant the slabs have settled in areas.  The settlement has led to instability and differential movement, leading to heavy vibration affecting local residents.

Geobear will be using their tried and tested ground stabilisation solution using one of their geopolymer materials. The material is injected beneath the slab as a liquid through small holes drilled across the bay. It reacts once in the ground to form an expanding geopolymer material that fills voids beneath the slabs and stabilises the areas.  

The project is one example of the type of schemes Geobear’s infrastructure division delivers. Richard Holmes, MD of Geobear Infrastructure comments, “Our non-disruptive solution allows the road to be operational with traffic management in place, as opposed to full closure with bay replacement. The project is a perfect example of how our modern ground engineering solutions benefit the client, and importantly, the local community.”
