Krinner Ground Screws

Was at the 4wd show here in Perth over the weekend.

One of the exhibitors was Krinner Ground Screws http://www.gscrew.com/ . Has anybody used them? I recon they'd be mickey mouse grouse.

I plan on extending the deck of my alfresco area within the next 12mths and I'll be seriously looking at these for the footing/post to sit the bearer/s on.

Something else they that I can see potential with is as a ground anchor in vehicle (4WD) winch recovery operations, instead of using the star picket or digging a hole to bury the tyre methods, which are strenuous operations.

I sent them an email to enquire a few months ago when I started my deck but didnt get a reply so shovel and crow bar it was for me.

I've used something like Enviropost in the uk, mainly for repairing rotten fence posts, and will probably use them for my carport.

I sent an email to find out the cost and was told about $20 for the smallest one, which is gotta work out cheaper than hours of hard digging, plus the cost of concrete etc.

Needs a big drill!

They sell a sort of block which goes in the top of the spike and then you can hit it with a sledgehammer Have a look here.
