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.
