Expansive Clay Soil

  Expansive Clay Soil and Foundation Failures of AS2870 The impact of expansive clay soil on a building depends on a number of factors, including the size, age and construction of the foundation, and the weather conditions. By addressing any concerns regarding a foundation, extensive damage can be avoided. Read on to learn more. We'll discuss Tough-Cells, Flocculation, and failures of AS2870. Expansive clay soils are a particular problem for new home foundations, and foundation monitoring is necessary to prevent extensive damage. Tough-Cells The use of Neoloy Tough-Cells in expansive clay resembling asphalt pavements provides a cost-effective and unique solution to the problems associated with such pavements. These materials are installed on top of a stiff biaxial geogrid and dual layer of Neoloy in the pavement structure. This stiff geogrid provides stability and multiplies the effectiveness of the Tough-Cell reinforcement. Biostimulation has been proven to be an effective alter
