In the greater Boston area the argillite bedrock and/or the overlying glacial till provide suitable support for a wide range of foundation systems, including high capacity end-bearing piles. However, locally and in an irregular manner, younger igneous dikes and sills had intruded the argillite, and hydrothermally altered it creating zones of highly decomposed, clay-like materials of soft consistency and medium plasticity. A case study is presented for a relatively heavy, pile supported cement storage facility at a site in greater Boston.
