Purchased a recreational lot in BC, but it's
zoned R1 residential, so BC building code
Want to build cottage, size 20'x20'.
The lot is flat on dense gravel, but it has
to much clay content to be used for an aggregate
in a concrete mixture, and the nearest aggragate
supplier is 30 miles away and charges $100 min,
for my 12 piers, 2' into the ground per code, to
deliver, then of course I mix and pour using
The bearing pressure of the lot gravel is rated
150 KPa ~ 3,000#/sq ft, ascertained by diggings
4' down for septic approval, and has fast drainage.
What do you guy's think about using Pressure
Treated wood for the piers instead of concrete?
I'm figuring, a slab of PT lumber at the bottom
of the hole spreading the area to about a sq ft,
with a 2' fastened 6"x6" PT vertical short beam,
as my pier, upon which the floor beams sit.
Naturally, I'd be careful and apply a serious tar
resin to the PT and end cut's to avoid rot.
