More About our Concrete Decking Block Shims

Want to ensure that your joists are well-fitted when using concrete decking blocks in your decking installation? Using these decking block shims is the way to go. They help to properly adjust the posts when fitting into concrete feet to create a consistent expansion gap.

Specifications:

  • Length: 78mm
  • Width: 30mm
  • Depth: 8mm
  • Number Per Pack: 48

Creating an appropriate gap ensures your joists have room to naturally expand and contract with changes in temperature and moisture. This helps to prevent common issues such as squeaking, warping, or buckling over time.

Each shim is designed to interlock, allowing you to build up to your desired thickness. This ranges from 2mm to 16mm so that you can customise the gap to the project requirements.

Quick Reminder: Make sure to remove all shims before laying any decking boards on top of the system.

Made a difference in making sure I had the same spacing when fitting in the joists - will definitely be using it in any future installations of concrete feet blocks.
