At HBD, we know how important it is to communicate safe land remediation methods to local residents, so here we wanted to reinforce and expand upon the information you will have read in the virtual exhibition room.

Whilst the current site is safe and secure, there are areas that need to be addressed before construction can take place.

Our step-by-step guide below sets out our approach to the land remediation.

Land Remediation at Phoenix 10 Walsall,
a Step-by-step guide to our remediation strategy

1

Excavation of Made Ground Materials in the areas underlying the footprint of the proposed units.

3

Crushing of oversized materials to provide engineered fill materials.

5

Grouting of worked out coal seams to a maximum depth of 30m.

7

Potential remediation of organic contaminants by biological degradation, and physical fixation of non-organic materials by cement if required.

2

Screening and removal of non-soil discards from materials deposited at the site.

4

Treatment of mine entries.

6

Placement of excavated materials to an engineered specification and under an Materials Management Plan to ensure that contaminants are not present in near-surface soils.

8

Fixation of groundwater contaminants within the emplaced grout (used to treat mine workings) to enable ‘substantial betterment’ of current groundwater quality.
