About Us

Being in the engineering field for over 35 years, Mr. Johannes Izak Du Plessis established JDA Line Bore CC in 2011, is based in Richards Bay, and specializes in On-Site Line Boring. 

This is a diversified method of precision boring. It is fast and precise, and the degree of accuracy gives superior results. The on-site repair capability saves expensive downtime and transportation costs, so these advantages make line boring very cost-effective, especially when machinery must be taken apart and be moved to a repair shop and back to be re-assembled.  Time after time, it saves our customers time, money, and gets vital equipment back in operation as quick as possible.

Our team is experienced, well trained, and react fast to ensure the best customer service, always. Today we have advanced equipment to ensure quality, and we use qualified logistics suppliers to ensure on-time delivery.

We are keen to build productive partnerships with our clients and will always work closely with you to plan, coordinate, and execute projects efficiently. We offer a high standard of service, quality, and workmanship.
