Increase Productivity and Improve Profit.

The new Chanspan Expansion Joint Channel System will speed concrete flatwork control joints by providing consistently better quality joints every time.

Put these revolutionary advantages to work for you:

  • Height/Depth adjustable and settable.
  • Keeps horizontal flatwork joints straight and also allows for smooth and stable flatwork curves.
  • Accommodates rebar reinforcements in flatwork.
  • Easy installation with 60 penny nails for flatwork and wood screws for masonry control joints. Set height/depth quickly with self-tapping screws (spikes and screws not included).
  • Choose either ½" or 1" joint widths in 10' lengths.


“With CHANSPAN we can get our expansion joints in the correct way, and keep on pouring. This saves me time and money.”
