The Nudura® Taper Top block measures 8′ long by 18″ high. The polypropylene webs are 8″ on centre.
The brick ledge allows the wall to continue above the brick ledge while providing a concrete width of 3-7/8″.
Nudura also manufactures a “brick ledge extension” which can be attached to the outside of a standard block using 6″ screws and plastic washers. The foam is cut away between the webs to allow the concrete in the wall to flow into the ledge extension. The extension provides greater flexibility (can be installed at any height), however it is more labour intensive.
