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 beam and block flooring.
