Ritchies secures grouting work extension at High Barns

Allocation of an additional £2.9M of funding from the Homes and Communities Agency (HCA) to Dacorum Borough Council (DBC) for ground stabilisation of historic chalk mines in Hemel Hempstead has led to a contract extension for Bam Ritchies.

Ritchies started work on bulk and compaction grouting at the site early this year following a £2.05M grant from the HCA but this was insufficient to treat the all the houses on the High Barns estate affected.

Since starting work on the contract, Ritchies has placed more than 3,300m3 of grout but it is estimated that only 50% of the chalk mines have been backfilled.

“The additional funding will allow work to continue on infilling the old chalk mines at Highbarns,” said DBC leader of the council Andrew Williams. “This funding will ensure that work will now be able to be completed, meaning that residents will see an end to years of uncertainty and worry about the future of their homes, and see restrictions lifted that have affected 430 properties.”

Ritchies and DBC’s consultant Hyder are now expected to complete work at the site in November this year.
