thanks for the input guys, back to the main question. . . I have concluded that below is an acceptable plan for the subgrade based on this discussion, TRUE??:
4" conc floor(typical for radiant floor, even done with 2")
4" Type XIV EPS foam insulation, 6 mil PE beneath to prevent R value...
thanks Oldest guy.
-- Will I have to hire and engin testing company to run density testing then during the compaction work?
-- MISTAKE! I WRONGLY posted the building code as 4000. It is 2500 psi in the case of interior slab. So not a problem for shrinkage probably.
Soil lifts and compaction schedule for solid sand under a slab on grade home 4" conc floor? Home will have CMU frost walls.
Building a 2700 sq ft home. Using 4" conc floor and radiant hydronic heat with tubes in the concrete. My spec for the floor is the following, what if anything can or...
hmmm, well I will get a chance to do it then. Sorry, I misunderstood the concern being for uplift proofing vs support. Yeah, not sure what I will run into on that, kind of worried about what I will find tamping it in. If it goes in real easy and I'm able to bury it like pushing a stick in mud...
thanks guys, OK, Simpson post anchors and 5/8" thread rod are in.
Worried about proof testing. . . what if it pulls out? plus, I will have to wait till it cures a bit . . . a few days before trying and Menard's is already pushing me out six working days for delivery of the dang 8" PVC pipe...
Ron, thanks for guiding me here, especially for reviewing my "process plan"!
I understand Simpson makes some great post mounts that have a slot in them. Requires threaded rod, J-rod etc. instead of rebar. This makes sense to allow me to fix inaccuracy of pier placement. What do you think...
OK, I'll try again. . . how about pier and beam guys? See attached pic
The idea being to NOT extend the posts up from each pier but let the piers support the beam and build the posts up from the beam.
One more thing. Forget about heaving, I believe I got that covered. Besides the...
Sounds like I have a an adventure in front of me here. I plan to go for it. My biggest concern is accurately placing the pile centerlines and making each plumb. Considering using a pile & beam construction now instead of just extending the pile up into a post due to probability of poor...
Hey Ron. That may be just the sort of solution I am looking for. However, before I jump on this, let me clarify my understanding and you can keep my running straight here. . .
NOTES: I'm concerned that reaching the point of being "muddy" will occur significantly before Minnesota min frost...
OK guys, Here goes again.
I last asked for your help stabilizing the roadbed for the 1/4 mile lane to my planned home across virgin soil. Now, I'm building a simple post and frame shed in the same area as this roadbed, laterally in the same position at the base of a small forested hill. The...
Well guys I put in about 20 dump truck loads(7 yd)in all-- much of that over just the basic fabric(not "GEOGRID" plastic) and it appears to pretty much have solved the problem. Of course, time needs to take its course to really prove this out.
I did not use the geogrid materials on this...
additional info you requested: . . . and MORE!
-- virgin land for the most part. No gravel ever saw this road until I dropped some class 5 on top of the concrete pieces last week.
-- the "road" is really just a farm lane that until I bought the property was used only by the farmer who made hay...
Here is half inch rod data. Process used: pressed on handle with both hands, if road took the weight easily I stopped. Likely, this applied less than 50# force. However, if the rod sank easily I put my whole 155# across the handle and let it drop till it stopped. I had to upload a pdf...
Thanks guys. I decided to buy the whole dang roll($345, big deal) and go for broke. Based on your input, oldest guy, it appears my A/B test was in the wrong range! Keep in mind my objective was to cause a significant effect, not necessarily to have both sides "work" (i.e. an experiment)...
OK, I will get a half inch rod and profile the road. Graph forthcoming next time I visit. . .
Keep in mind the 1.5 CBR "rating" reflects only a seat-of-the-pants rating for the worst places on the road, mostly showing up where vehicles wheel travel and in the lowest area near the hayfields...
Here is a link to my dropbox that shows the photos of my first subgrade re-work, hopefully "Dropbox" routing will work.
It is very cumbersome to place images on this forum I see, and my earlier attempt allowed only one to be placed at a time.
Going to Dropbox you can access the whole folder...
OK Oldestguy, here are some more details: I expect only 5 to 10 heavy trucks to pass across this roadbed in the next six months, mostly my little Isuzu Rodeo 4x4. When home building starts next spring there is the well drillers truck, cement truck loads, and home building truck supplies over...
Thanks for joining in the fray msucog. It appears you offer 3 potential remediations. The first being a high end, deep, fix with the last (turn it over, let it dry, compact in lifts) being the one I may consider. I can appreciate what you're saying on the deep fix, but adding 3% cement to...
