Precon blocks are dense, lightweight and precision-made. They are provided in a range of sizes from 100 to 215mm thick. Specials are available, including quoins, half quoins and cavity closers.

Highly versatile, these blocks are suitable for a range of applications, including external walls (above and below damp courses), partitions, separating walls and floors. They are manufactured using Patersons' own quarry products and are delivered in volume by the Precon fleet.
