We had a small crisis at work, our loading bank for chip and residues was falling. The would stop our operation. The team at Interbloc gave us a solution that we could dismantle and rebuild our wall in 1½ days. The advice was good, the service prompt and the result was great. I would recommend Interbloc when you need a fast, stable wall for a competitive price.

We recently purchased Interbloc Blocks and the whole process from initial contact to delivery and installation was a breeze. The team at Interbloc were helpful, prompt and even when I increased our order after half the blocks had been delivered it wasn't a problem. The Interbloc locking system makes it easy to construct and an end product that looks great. Thanks to Dion & the team a pleasure doing business.
