Single Face Wall Form
Single Face Wall Form
(OP)
Can anyone provide me with the vendor and/or product name specializing in single face wall forming?
Alternatively, does anyone have an innovative, or tried and true method for building single face formwork for an 18 ft. high wall? I am particularly interested in an ecomoncal means for design of a foundation to take out the lateral loads.

Can you please clarify your situation a little further?
What retains the concrete on the 'far'side? eg are you concreting up near a vertical rock face (in which case can you anchor your form to it ?), or is it an adjacent building (in which case will the far wall tolerate the concreting pressures ?)
Also what is the general site geometry and ground conditions - are you working in an excavation, for example?
Site unseen - can you use a system of inclined struts (30 to 45 degrees to the vertical, founded on inclined spread footings at 'floor' level) plus vertical ground anchors close to the form (to resist the vertical components of the strut forces) ?
RE: Single Face Wall Form
The excavation is 28 ft. deep and the perimeter of the excavation/pour is irregular (some walls are at 45 deg. angles). In some areas we will be pouring up against an existing concrete basement wall and at other locations we will be pouring up against a braced excavation.
Your suggestion regarding the use of inclined struts is the option originally considered; however, anchorage of the form to prevent overturning near the base of the wall and footing design for the inclined sruts to resist the high lateral forces (taken via soil passive pressure resistance and friction) is becoming costly.
I'm not sure why you suggested inclined footings for the struts (the bottom of excavation is flat). Could you explain?
RE: Single Face Wall Form
My 'inclined footings' was personal shorthand for 'make your excavations for the strut footings wedge-shaped, with the slope perpendicular to the struts'.
With such an arrangement, you don't need to rely on friction or on lateral passive pressure, and your footing problem may be reduced considerably. You do, however, need to assess a permissible bearing capacity which allows for the inclination of the load. I seem to recall that there is/was a NAVDOCKS publication that gave advice on that.
I would address conditions at the base of the form in the same way. That is, I would have two rows of struts, (with all uplift taken in ground anchors).
