Our Story

Concrete lock blocks have been delivering interlocking concrete lock blocks throughout the South Island since 2005.

Alwyn Clarke founded Concrete Lock Blocks in 2005 after many years working in the concrete industry. After years of manufacturing concrete as part of his business - Canterbury Mini Mix, he was concerned about the amount of concrete wastage created daily. This led him to set up a system that would help alleviate the waste being dumped in our landfills by manufacturing recycled concrete lock blocks. .

Today, we are the largest and longest producer of concrete lock blocks in the South Island. We can help supply mass produced lock blocks of varying sizes, or custom designed and made to order.

All of our concrete meets the NZRCA standards and NZ Safety Lifting standards
