GDH is the cornerstone for SigmaRoc’s third Platform that also incorporates the high PSV Quarry, FoelFach. With a 40% stake in GDH (and ability to purchase the remainder), SigmaRoc has a significant footprint in the region.
GDH is one of Wales’s largest independent suppliers of aggregates operating out of six quarries; three asphalt plants, six concrete plants, and a wharf operation, as well as a civil engineering division delivering significant infrastructure projects.
Foelfach is based in Carmarthen, Wales. It produces single size and fill aggregates as well as high PSVaggregate of which only 9% of quarries in the UK are able to produce.
It supplies materially internally to GDH as well as to outside customers; primarily asphalt and contracting businesses.
