Some 330 homes are being built on the site of a former container depot on the outskirts of Liverpool.
At Cressington Heath Keller Foundations have installed stone columns beneath housing as part of a major regeneration project. The site was underlain by varying thicknesses of made ground ranging from 2m to almost 9m.
As the site was predominantly two and three storey housing and the made ground was granular and mixed cohesive, ideal for treatment, vibro techniques were employed as an economical solution for the foundations.
Keller's Vibrocat ,with the greatest depth range for vibro in the UK , was the ideal tool to treat the deep areas with stone columns and almost all of the plots in the deepest areas of fill were treated by Keller.
