Composite Foundation Walls?

Hello all,
After belittling my state for it's poor building codes, builders and lack of innovation in my last question, I came across this product and am really intrigued:

In my state, erected in half a day with the sill plate and waterproofing. Cost is slightly higher than a poured foundation, but when I take into account the waterproofing is included, I think it will be a wash. It is fairly new though, and I like leading, not bleeding edge. Curious what Martin, Dana and the others think of it (or if you would use it).

Finishing a finished basement

We purchased a brick veneered ranch home in the St Louis area about a year ago. The home is about 44 years old. The brick is in very good condition, but doesn't have weep holes at the bottom. In several areas that I can check there is an air gap between the brick and sheathing of the 2 x 4 framed wall of the house. This gap appears to be 3/4 to 1 inch. Currently the basement is finished except for 2 utility rooms. The finished areas have 1/2 inch drywall over 1 x 3 or 2 x 2 furring strips attached to the foundation wall.

Basement ceiling insulation

I am interested in insulating my unfinished basement ceiling. The primary reason I would like to do this is so that I can have separate conditioned zones since the temperatures between floors are not consistent. The main floor is about 2200 sqft, as is the basement. Currently there are only 2 registers feeding the basement and no returns.

Basement floor underlayment

I am considering putting down a 12mm laminate floor in my Michigan basement, with the primary goal of "warming up" the floor surface. Currently there are vinyl tiles on the floor with many of them missing. The house was built in the 1950s and has a low (7'1") floor to ceiling joist bottom height. What I am considering is using Selitac underlayment by Shaw Floors, which is a relatively thin (2mm) foil-faced, insulated material that would not contribute to headroom problems. I would tape all of the abutting seams of each piece as recommended.

How to insulate and finish basement when there are signs of efflorescence?


I am re-finishing/insulating my basement in a 1930 home in Zone 4 (Pacific NW). I am planning to do it as follows from foundation to interior which meets local building code: Basement Concrete Foundation Wall > 1”XPS Rigid Board(Pink Owens Corning) > 2x4 Studs against the XPS > ROXUL insulation in stud cavities > Sealed Poly Vapour Barrier > Drywall.

There is evidence of white efflorescence on the basement walls indicating that there may be or has been in the past moisture seepage. There have been no flooding events. Being a 1930 house, the foundation is not waterproofed.

Foundation Uplift

I am planning to build a 2 story standard colonial (28 x 36) in lower Michigan using Sips upper walls and a PWF conditioned crawlspace foundation. I am somewhat puzzled by how uplift is prevented in some of the PWF recommendations I see proposed. I will not be back filling the interior walls so it appears there are 2 options. Pour a 3-1/2" concrete floor( attach to wall via a screed board with embedded fasteners) or build a treated regular joist floor?
