Boardwalk Stob replacement

[Fredsboy]

Friends, you lot seem to have very varied experiences so a little off topic but: I am repairing an existing boardwalk in an Alder Carr. Where it is sinking (original telegraph poles rotted) I plan to add side stobbs to bear the weight. Any proactical dvice ? Is it best to pre-point and drive in or dig out and place flat end down?

Paul

mods please place appropriately If I have started in the wrong place - apologies

I don't know but if the bog is deep sphagnum I would expect a pointed stick to continue to sink. Also glad to see you using wood and not recycled milk bottles which pose a disposal problem for the future. Good luck

 

BTW Alder Carr is a tautology.

Why not use facines   under the board walks?

 

Were used on acient bog trackways and under roads and railways

Facines… new to me but did so,e digging and seems an option, do you have much experience with these? Dead or live facines recommended?

thx

Thx open spaceman.. good observation on continued down ward travel and pretty bleeding obvious once pointed out… saved me some future pain there I think. Yes it is very silty ground.

The timber posts should have a large diameter to give the most surface area to carry the load of the walkway

best dig them in then drive last few inches to tighten them up

in the early days of railways sheep fleeces were used to get across marshy ground i believe in some pleases its still under the lines that was put down in the 1800s

Going to to my best to log the work and offer up pics. All first time for me so please critique and offer suggestions but let's keep it objective and friendly. The Carr (looked up the Grammar) is at Surrey Wildlife Trust location in Godstone, private but shared with assorted dog-walkers and teens. Not sure when it was first built but had telegraph poles in series laid on a silt bed with oak boards at 90degrees. There was also 'wheelchair kick board' but the teens relocated that into the lake. The original boards had chicken wire stapled on for grip. When it first started to rot a few years back fresh stringers were laid direct on the boards although some of the original volunteers said they found evidence of stringers on boards on stringers on boards on the poles - so a third layer of repair.

You can see that some boards have rotted and naturally dropped away, other had some teen help, leaving old chicken wire. The Board wlak is about 100 meters long and following TCV best practice has many kinks and turns making it far from straight. There are two small bridges over 'trickles/streams' .
