Have you heard of Diamond Pin Piers?

[HoustonDave]

I read about them on another forum.  This should not be considered an endorsement of their product, I'm just interested in people's opinion of the design.

Would you trust a cabin to this design?  What if it was on a slope?  Seems an interesting design.  The concrete head sits on the surface and 4 pins up to 80" long are driven at angles through the head into the soil using a jackhammer.

Thanks.

Dave, I think it is a great design, but a little expensive, so I designed my own.

Poppy's Pin Pier desgin starts on page 3 of my cabin thread.  http://countryplans.com/smf/index.php?topic=7241.40

I believe the manufacturer has a max. soil slope specified in their info.

Dave, I asked the same question back in March '09.  http://countryplans.com/smf/index.php?topic=6512.0

Dave, I also wrote a report on my experiences with my own design.  http://countryplans.com/smf/index.php?topic=7709.0

That'll teach me to do a search first eh?  Thanks Poppy.

I think we had another discussion on them too. 

There are also expensive helical piers that can be screwed into the ground with a Bobcat attachment.

   In the ever expanding Texas soil you may want to run your piers to bedrock. . .    Find someone who installs telephone poles.   Generally they will drill holes for about $100.00 ea.

Thanks Bay.  I'm looking into that.
