Step 12. Soil Bearing Test

The basis of a strong, high quality build is achieved thru the strong focus towards attention to detail and superior quality standards of methods and materials. One such detail that we firmly believe in when it comes to foundations, is the determination of the type, composition and compressibility of the clay that we will be building our new foundation on. This test is called a Soil Bearing Test. The Soil Bearing Test is carried out by an engineer performing a site visit, post excavation to review the types of clay and site conditions that we will be building on. This engineer will also take various samples within the base of the excavated hole, bringing them back to the lab where they will be tested for Compressibility and Sulphate Levels. This two part test answers two very important questions for us. First how wide should the footings be to hold the weight of the new home determined by the Allowable Bearing Pressure. Secondly what type of concrete should be used due to the level of the natural Sulphates in the clay. Our respective report for "The Oxford" called for 24 inch wide footings and for an upgraded 35mpa type 50 concrete which has the highest resistance to Sulphates.
