Light Oppdal and Offerdal slate have excellent flexural strength (up to 46.5 MPa) and we have a standard slate thickness of 2,5 cm for pedestal systems. Minera Skifer has conducted tests in collaboration with CBI/SP (the Swedish Cement and Concrete Research Institute) to determine the dimensioning of slate slabs for use in pedestal systems. In terms of load, a thickness of 2 cm is sufficient, but for weight and stability we recommend a thickness of 2.5 cm.
