How to use Super Saddle
1. To get a high quality level and flat 12-foot strip of concrete slab, first set the side forms around the outside of the slab with the top of the form boards at the level of the slab surface.
Measure over 11’6” from one side form and run a stringline between the perpendicular side forms at the elevation of the slab surface—from the top of one side form to the top of the parallel side form on the other side of the slab.
Along the stringline, drive a 12” to 18” piece of #3 or #4 rebar (depending on the subbase) about every 6 to 8 feet.
4. When the top of the rebar is close to the finished slab surface grade, put a Super Saddle onto it (the green ones if you’re using #3 bars or the orange one for #4 bars) and tap it down with a framing hammer so that the bottom of a 2x4 mounted in the Saddle will be at the final grade of the slab surface--the top of the rebar stake will be exactly 1 inch below the final slab surface. This can also be accomplished using a laser level and rod.
Mount a 16-foot 2x4 into the Super Saddles, resting on top of the side forms at the ends. This is your screed rail that the Super Saddles are supporting along the top of the slab surface. The bottom of the 2x4 will be at the elevation of the slab surface so it won’t be in the concrete as you are pouring and finsihing.
Place concrete into this strip and using a 12-foot 2x4 with ears so that it can run atop the screed rail and on top of the side form, screed the concrete perfectly level.
Measure over 12’1” from the edge of the screed rail supported by the Super Saddles and run another stringline across the slab then drive another set of rebars to support the next line of Super Saddles.
Pour the concrete and using the 12-foot 2x4 with ears on both ends that will ride atop the rails, screed between the two screed rails supported on the Super Saddles. Both of these screed rails will be out of the concrete with their bottoms at the slab surface elevation.
Pull the first 2x4 and use it for the next strip and simply continue leapfrogging until the pour is completed and screeded flat.
Bull float the surface as usual, being careful not to bump the Super Saddles.
11. After the bleed water is gone and you can get out onto the slab, pull the Super Saddles and fill the small round hole with concrete. Leave the rebar in the slab, 1 inch below the surface where it is unlikely to get hit during joint sawing.
12. Trowel the slab and admire your work.
13. Collect the Super Saddles, rinse them off, and string them together on a piece of tie wire and save them for your next project.
