Large screw type piled decking foundations

[Post and beam]

I have started to get a load of facebook adverts for a type of decking solution that uses what look like 5 foot long wood screws driven into the soil in a square pattern arrangement.

As i will need to build up the area behind our new build by as much as a metre to give us a level patio area i wonder if this might be a good solution.

So, does anyone recognise what i mean and have you used it or considered this product?

I did mine with 15mm thick galvanized plates concreted in place.

 

 

The end near the house sits on a blockwork ledge formed when we did the foundation. Secured with brackets.

Decking looks OK when it is first installed but with softwood it does not last long.  I doubt the timber screw piles will be very durable.

My decking was installed over twenty years ago and is in great condition. It is exposed to sun and wind (it's about 1m above ground level) and I think this helps.

The piers sit onto concrete pillars in the ground (holes drilled with a huge auger).

 

I treat it every few years with Hicksons Decor wax (sadly now ceased production).

Yes the sun and wind will dry it and that will prolong the life considerably.  The concrete pillars will help a lot too.  20 years is very good.

I dont think he mans the screw piles are made of timber. They would be galvanised steel.
