Hilbre island .. Fire

We're waiting for Jill Doughty to read recent responses and update the status.

Dear Wirral Metropolitan Borough Council,
I am writing to request minutes of the meeting where the decision was taken to use inflammable material rather than concrete on Hilbre island resulting in fire. This decision lead to massive pollution, possible collapse of a cliff and endangered lives.
I request the details of the process of decision making for taking such reckless risk

Yours faithfully,
Jill Doughty

Dear Ms Doughty,

 

Thank you for your recent request made under the Freedom of Information
Act 2000. Please accept our apologies for the delay in issuing a
substantive response. As mentioned in my last correspondence, our
Environmental Health team have been extremely busy, conducting a thorough
investigation into the Hilbre Island incident.

 

Our response to your request, is below as follows:

 

With regards to minutes of meetings, this project was carried out by our
schedule of rates contractor, would be classed as a small scheme and a
structural project. As such a number of site visits, emails and
discussions with the contractor was carried out with no need for minutes.

 

With regards to the decision of material. In a report in 2016, there were
a number of options talked about with regards to stabilizing and filling
in the cave below the overhanging cliff. They were:

 

· Pumping a cementitious based material into the void;

· Filling the cavern with imported or site derived fill material; or

· Filling the cavern with material harvested from the adjacent beach.

 

The cementitious or imported concrete option was not viable. The access to
the island made it impossible for a concrete wagon to get adjacent to the
site and making the concrete at the site would have taken far too long
taking into account the size of the void. Also it would not be possible to
get a tight finish to the underside of the overhanging cliff, therefore
the collapse of the cliff could not be ruled out. The concrete needs to
flow and this would have left a void and no support for the rock face.
Also, the curing time of the concrete needed to be taken into account.

 

The filling of the cave with material harvested from the adjacent beach
again would not have supported the overhanging cliff, in a similar vain to
that mentioned above. The tide was also an issue with the material being
washed out to sea once placed.

 

The material used for the infilling needed to be able to be brought to the
site in small enough sections for the vehicle limits, be able to be placed
into the cave taking into account for the difference in level between the
top of the cliff/beach and expand to fill all voids/fissures within the
rock face.

 

Expandable sprayed foam is a class ‘A’ material used in bulk filling for
Mines, substitute backfill and void fillers. It is a strong alternative to
conventional closure methods.

 

Advantages are:

Cured in minutes, freely flows into voids and cracks, ease of application
contributes to less construction time, resistant to water penetration,
high structural compressive strength and can last a lifetime.

 

I trust this will be of assistance to your enquiries.

 

Wirral Borough Council would like to thank you for your patience &
understanding with this matter.

 

You have the right under Section 17 of the Freedom of Information Act 2000
to ask for an internal review if you are dissatisfied with the information
provided to you. Please direct any request for an internal review to
[1][Wirral Borough Council request email] and your request will be allocated for
review.

 

Yours sincerely,
