Pacific Build Supply has various options for decking. We have the tried and true Pacbld Base 20mm board to give a superior substrate for tiles, membranes, and high build paint systems. Along with this we also offer the Parklex composite decking material, a non-slip, no maintenance alternative to traditional timber decking, yet giving you the same look.


Block Tek is a high-density composite decking for exteriors, extremely resistant to atmospheric changes in humidity and temperature, ideal for patios, walkways and outer perimeters of buildings.

Pacbld BASE

Pacbld Base 20mm will give a superior substrate to be waterproofed and either tiled, membrane placed over top, or high build anti slip paint system. Why choose Pacbld Base as this substrate over anything else is simple:

  • Superior water and humidity resistance, including frost resistance

  • Highest possible resistance against delamination being monolithic

  • Superior durability

  • Superior impact resistance

  • Easy to work with and install
