Insitu Testing
Sutton
Southern Testing were contracted
to carry out a ground investigation and advise on foundation design for
two blocks of thirteen and sixteen storey buildings on Chalk. Due to the
high column loads, the designer initially assumed that piled foundations
would be required. However, the results from boreholes indicated that good
quality chalk was present from near ground level and that raft foundations
might be feasible.

Oxford Airport
Three phases of ground investigation have been undertaken to provide information on the construction thickness and underlying soil conditions of existing apron / pavement areas, “airside” at Oxford Airport. Information collected from the ground investigation will be used in the design of new pavement and apron areas. The scope of works have comprised Blacktop/Concrete Coring, Insitu CBR Testing, and DCP CBR Testing.
Gatwick Airport
Southern Testing have completed numerous phases of ground investigation to provide information on the construction thickness and underlying soil conditions of existing apron areas, “airside” at Gatwick Airport. The scope of works generally comprised Coring, Insitu CBR Testing, DCP CBR Testing and factual reporting.
