I just had Bill Bulough design my slab and it was dug out today, he is the designer for Amadore homes and underspeced it for my desires…was… 20"perimeter and 4" at 3500 psi… I’m doing a 24’ x24’ ,which is the largest Alaskian Guilderland will allow. I upgraded to 24" on the perimeter and 6" slab, sloping to 10" around where the lift posts will be. Its lined with rebar and 6" mesh. Using 4500k psi …and this meets or excedes most lift requirements. Being poured monday if you wanna come see what it looks like raw over the weekend.
I prefer the alaskian for the lift as a floating slab on foundation/footings has limitations at to how close the lift can be mounted to the edge of the slab. The Alaskian lets me get closer to the garage wall if you will.
For those curious, the dig out and slab runs in the 4k+price range.
Today we poured the hot tub slab…took 3.5 yards and is 10x15’
pic is sideways and this was before smoothing/light brush
I would come take a look if it wasn’t such a long drive. I’m definetly going with an alaskian slab. I don’t really have to worry about dig out since I actually had to bring fill in last year to grade the floor up to where it needs to be.
