Warning!

The prediction of the column diameter is just indicative and an experimental assessment is always recommended. The Authors don't take any responsibility for inaccurate prediction.

Diameter prediction is based on the Ochmański et al. (2015) article "Prediction of the diameter of Jet Grouting columns with Artificial Neural Networks", Soils and foundations, Vol. 55, Issue 2, p. 425-436
