The clay soils of the Assiniboine River delta in Brandon Manitoba are highly plastic. Liquid limits here often exceed 60%, and plasticity indices can reach 40. These values directly control how the soil behaves under load and moisture change. We run Atterberg limits tests per CSA A23.2-2A on every sample we take. The results feed directly into the USCS classification, which then guides foundation design. For projects on these expansive clays, we combine Atterberg data with a ensayo de consolidación to forecast long-term settlement, and we use ensayos de permeabilidad en laboratorio to assess drainage rates in the clay layers. This integrated approach gives contractors in Brandon Manitoba a complete picture before they pour a single cubic metre of concrete.
Liquid limits above 60% in Brandon Manitoba clays mean high shrink-swell potential. Ignore the Atterberg numbers and your foundation will move. Period.
