Background
Quarrying has been an on-going activity at Cwm Nant Lleici for over a century.
Our shareholders, Huw Francis and Robert Sullivan, originally purchased the Cwm Nant Lleici site and its surrounding farmland (a combined area of circa 100 acres) around 1989 for the initial purpose of producing dimension stone used in the construction industry.
Following acquisition, a series of tests confirmed the stone suitable for use in road wearing applications.
Focus switched accordingly to producing high specification aggregates. Given the quality and scarcity of the product, it was not long before the move attracted the attention of a number of national and international quarrying companies.
In 1996, an agreement was reached to sell Cwm Nant Lleici site to Camas Aggregates (which subsequently became Aggregate Industries, part of Holcim Group). However, Huw and Robert retained an option to buy-back Cwm Nant Lleici after 25 years.
Aggregate Industries subsequently operated Cwm Nant Lleici until Huw and Robert exercised their Buy-Back option in 2020. Production at Cwm Nant Lleici ceased in 2021 and Huw and Robert completed their re-purchase of the quarry in October 2022 via their new company, Hygrove Aggregates Limited (“Hygrove Aggregates”).
Cwm Nant Lleici has supplied aggregates for use on all major motorways throughout the United Kingdom in addition to several airport runways (including Heathrow and Bristol) and also to motorsport racetracks such as Donnington Park where high PSV surfaces are vital.
The aggregate deposit at Cwm Nant Lleici is classified as a National Resource which must be protected and acknowledged as such by Planning Inspectors, Planning Authorities and Highway Engineers throughout the UK.
