Hi Will,

If the surface is permeable I think that in most circumstances it would be 
okay to leave it in place. However, if you are unsure why not get the 
contractors to remove it? I used to believe that it was a difficult operation 
to remove a cellular confinement system, but now that I've seen it done I 
realise that I was completely wrong. A mini-digger can pull out a whole mat 
in one move; then you are left with a pile of stones which mini-diggers are 
well designed to deal with. A small installation can be removed in minutes.

All,

     Would appreciate advice/comment

I have a site where a pile and beam solution has been recommended within the
RPA of a lime tree (developers original arb report) for construction of a
dwelling, the construction team will require access to the RPA to
facilliatate works so ground protection will be required in this case due to
type of works  cellular confinement is likely to be the best option as
opposed to mats (contractors normal choice). I wonder if anyone has
experience of this being left in place in the void  under   block and beam
or should it be removed, obviously as far as long term structural integrity
is concerned a structural engineer will be consulted by the construction
company. Any comments welcome.



Will
