As a visitor on a recent studio tour around Merrickville, Ontario, I discovered the work of Pieter Doef. His human figures are about half life size, modelled in clay, then cast in concrete from a plaster mould of the form. Most of the sculptures in the gardens of his rural property are of people, but there are also some abstracts forms.Pieter explained that he uses a simple mix: one half builder's sand and one half cement. He's also a prolific painter.
There are more images on a Facebook group started for him:
