Upon moving to the Denver Metro area, from the East, I was confronted with some new (to me) framing techniques. Specifically, floating framing in the basement. This is to mitigate the effects of expansive soils (bentonite) Floating walls are regular stud walls about 6 inches shorter than usual, bolted to the floor joists of the story above, so the walls hang about 6 inches off the floor. A 2 x 4 base plate is anchored to the floor. 8-10 inch spikes pass through holes in the bottom framing member and anchor into the base plate, keeping the wall plumb. This allows the slab to rise and fall approx 4" without affecting the framed walls. While this is common for this area, I have not been able to find any standards, guidelines, or methods of construction in print.
My job requires me to conduct on-site service calls for a specialty cabinet retailer. Because of this, I am involved in the planning (& aftermath) of many basement remodels.
Of particular interest is the (apparant) lack of consideration for the mounting of cabinetry on these floating walls. In many instances, I have witnessed the same carpenters who installed the framing, mount base cabinets resting directly on the floor, and screw as usual to the floating framing. The framing must float to mitigate the vertical movement of the soil. Imagine the impact to the base cabinets when the floor rises 3-4 inches, and the cabinets are mounted securely to the walls.
I have only happened upon 1 contractor who had a solution for this. Usually I am met with blank stares.
I would welcome any input, from any source, of where I might find some type of "official" information on this topic.
