I like the plastic. Liniar have some great options. The problem is where do you buy it? I can see lot's of information about it but not anywhere that sells it.


I think they might actually sell it directly. I seem to remeber that there is no minimum quantity aswell.

You can sledge them in or push them in if you are lucky and use the offcuts as ground anchors.

There is a good point about the unforseen effects downstream. It would be appropriate to put down some planting or fascines etc pegged to the base. That will slow down the flows along the edge and help prevent scour occurring and the ends of the wall which should be tied well into the banks. That will help sediment build up and vegetation to establish in the long term. Which will help shade the plastic and improve their longevity which to be fair is already pretty good.
 
Have you considered old railway sleepers in RSJ supports?

Of the softwoods Douglas Fir is often used for heavy construction work. It's certainly tough but I don't know its long term durability in a wet environment. Some independent sawmills seem to specialise in the stuff. I was quoted £20 a cu.ft some years ago, which seemed a very reasonable price to me.
 
You could run into serious issues with the EA who can be paranoid about work increasing the flood risk either up or down stream so I would have a talk with them. I've a stream that I'm looking to Spile and for stakes I'm going to use whatever comes to hand, Hazel, Ash, Witch Elm and Sycamore. With mainly Willow weaving.
 
Been there done that....so my advice is do nothing to that river bank without consultation and specification from and with Environment Agency, Rivers Authority, your insurance company. If you don't you could end up in jail. Simple.
 
we had a watermill in France, similar problems...
I used Oak for the posts then back filled with heavy stones getting lighter as I went up.....some decent soil on top and pockets for the
then planted Willow sticks ......u'd never know uness u looked carefully...
The job was still good after 16 years when we left.....this was situated near the infeed for the mill.....
sorry no photo's.......
