Curious to as if anyone here has constructed a house on piling in
Colorado or if anyone could tell me what would be required. I am
wondering what methods you use, or would use where the piling meets the
ground. I guess I am assuming a wood piling here.
Where I am and work, we, on the beach, either dig or jet with water the
holes at least half the piling length into the sand.
I have found that in most places of Colorado, Sonotubes are used to
make a pad for a post to rest on for maybe a deck or a stair. What I
have not found is an entire house constructed upon these. I have an
interest in this type of construction to do away with a typical
foundation or slab. Also, the underside could be used as
Any reply and info appreciated.
In general, the use is in CO is to provide support for the low
side(s)/point(s) in mountainside-type locations rather than for the
raised height to avoid tide/storm surge in beachside construction.
Can't do the water jet or dig easily in granite, either, which makes a
big difference in how the construction itself proceeds.
Don't see anything to prevent doing whatever, but particularly for a
year-round dwelling a raised dwelling will require additional attention
to insulation, etc., for the cold climate. If at a high elevation and
particularly on western slopes, unless fully enclose the area it may be
nothing but a catchall for snow when the wind blows.
I guess my whole intention would be to get rid of a basement foundation
for one. Most likely the use for the underside area as a parking
stall/storage/workshop, so it would be enclosed and nearly appear as a
normal two story. One main difference in the front elevation would be
the entryway on the upper part of the structure. Insulation expense is
noted, and with a concrete board finish underside covering is new code
here at least (for fire).
When used, are they generally on a pad of poured concrete? Or are they
dug into the ground?
Here the rule of thumb (apply in certain areas) is half in half out of
the ground. What I know of in Colorado, for example, is that there are
minimum depths for footings and foundations all based on geographic
location and altitude. 8 feet being the min depth in a place such as
Leadville. Would the same apply to a CCA post embedded into the ground?
Would they allow a concrete pour around the piling? If you must use a
concrete pad, I assume that this pad must be 8 feet deep as well to
account for frost line?? Either way, what rules would apply if any
about a slab poured underneath for parking and general ground cover?
Thanks for the replies,
I suppose I may be in uncharted territory here.
All based upon local codes and ordinance I am sure. I assume that I can
use sonotubes with a traditional foundation depth and place the pilings
on top. I suppose that my only wonder is the spacing of the pilings
now. Here the rule of thumb is 4 pilings per 100 square feet, 6 per 200
