WSP Environmental and their client, Westbury Homes, recognised that there
was potential for significant savings relating to the Piele Park,
Haydock site development
costs if a observational method was used for the grouting Potato Delft
Coal seam, which had been worked locally and was dipping below the site.
Our work comprised site
supervision of the work. As the adopting authority required the road to
be grouted in any event the records from these were used to determine which house
grouted. In addition, two mineshafts known to be present on the site were
found and capped.
Finally a completion report was prepared that was forwarded to the Coal
Authority and the NHBC.
