Background

Big C Rock Engineering was founded by Pierre Christiaan Cronjé after he obtained his professional Rock Engineering qualification in 2000. Pierre has vast experience in the most challenging mining environments in South Africa and abroad.

Pierre established a conclusive training initiative, hence the rapid expansion of Legal Rock cc as a training provider. As mine Health and Safety experts, Legal Rock implemented an outcome-based training solution.

Legal Rock cc has been awarded the ISO 9001 certification, and is in the process of attaining its MQA accreditation.
