Sinking concrete slabs can be lifted with ease – Accolade Park is a perfect example

GEOBEAR HAS been lifting sinking concrete slabs at sites throughout the UK for decades.

Typically, a site may experience slab settlement occurring over time and in some instances, if monitoring is not in place, they drop beyond acceptable tolerances. Where this occurs urgent remedial action is required to ensure the site is safe for use. Immediate closure of an operation unit due to this issue is unthinkable.

On the widely publicised Accolade Park site in Avonmouth, Geobear were contacted to provide a solution to the issue of sinking floor slabs across a large area of the site. The reasons for the sinking slabs had been debated in the courts, but ultimately they needed a method to re-level the site without hindering its operational use. 

The 80,000m2 site had up to 36mm of movement to its slabs in places. The decision was taken to use the Geobear ground injection method to stabilise the made ground beneath the slabs and lift the slabs to within tolerances. The scale of the site meant it would take months for Geobear to stabilse the area, however, with minimal plant and operation equipment the work could be carried out by isolating single aisles. Stock would be removed from the bottom bay and the team would follow an engineered injection plane to stabilise and relevel the site. This prevented any significant loss to operational time. 

Ground injection of geopolymer was invented and pioneered by Geobear, it is also used to strengthen the ground beneath footings and slabs to enable mezzanines or additional storeys to buildings.
