Ground strengthening and stabilization of residential homes, Glasgow
38 properties situated within a large residential housing estate in South Glasgow, constructed across a former limestone quarry. Properties were identified by the engineers as showing cracking/distortion in excess of 15 mm. URETEK were contacted to provide a solution to the problem that would result in minimal disturbance to the residents.
In total over 900 linear metres of walling (both internal and external) were treated to a depth of 4.00 m below ground level. Pre and post treatment dynamic penetrometer testing was completed at 5.00 m intervals along all the walls, with the on-site engineer signing off properties when an increase in bearing capacity of the treated soils had been achieved. The ground conditions encountered were made ground/in-filled materials to in excess of 20 m below ground level. Due to the partial treatment depth this work was undertaken with no guarantees.
URETEK Geopolymer Injection was the appropriate method to stabilise the shallow soils and improve the bearing capacity. The URETEK ground stabilisation works took 16 weeks to complete and were carried out without the need for the tenants to move out of their properties.
All post-treatment dynamic cone penetrometer tests recorded an increase in bearing capacity allowing all properties to be signed off as completed within the 16 week deadline. The client chose to use the URETEK systems due to the minimal disruption that would be caused by our works, to the elderly residents along with the speed at which the properties could be successfully treated.
