Re: Gabion wall within RPA

What is the function of the wall? Do I presume correctly that it will rest
on top of the soil and there is zero excavation involved? Is a laid-up-dry
(no mortar) wall an option? What are the real (e.g. effects of electrolysis
upon the wire mesh containment)  and expected (guaranteed by the
manufacturer) useful lives of the gabion? Why do you believe that a
cellular web product (presumably gravel-filled) might be necessary? Has the
net effective load been calculated and the carrying capacity of the
soil/effective depth of compaction been determined and compared? Has the
use of non-woven geotextile been considered?

Hi all,

I have been asked to assess the impact of installing a gabion wall with the
RPA of a neighbour's tree and was wondering if anyone has had experience of
this?

I am assuming that because the stones will allow water and air infiltration
that the wall wont have any significant impact on the tree?

In terms of soil compaction, should a no-dig foundation using Cellweb or
similar be specified to spread the load of the wall?

I look forward to hearning your thoughts.

Thanks,

Lee
