I see contractors are undertaking work of this nature around Blisworth tunnel, to protect the bankings and hopefully prevent slippage.
I've seen this type of work undertaken on railway embankments, and of course at Braunston tunnel repairing that slippage.
Whilst obviously an expensive process, which creates its own problems, would this kind of work have prevented the Easinghall slip ?
Having no civil engineering experience, I don't know if the simple soil embankments can be protected in this way ... what are you nailing into ?

There will be an expert who can explain it.
I imagine it takes about 3 weeks.

Maybe the idea is similar to ice boots. How long are the nails, I ponder?
Terracing would be better, probably.

I've seen a bank nearby here stabilised, they left a length of the steel "nail". 30mm pipe, 6mm wall with a rounded spiral thread. Drill hole, probably 5 or 6 metres, don't know really, inject a concrete mushroom at the far end, put 2 inch steel mesh on the surface and anchor with a screw plate. Every couple of metres over the bank.

It's the council doing the work to secure the road over the tunnel.
There are of course, lots of soil cuttings on the system and the costs would be prohibitive anyway, but I just wondered if the system could work.
I suppose the hope remains that very few cuttings have slipped in their 200 plus years life, and the exceptional wetness is the primary cause.
