Hermitage Quarry

Hermitage Quarry, near to Junction 5 of the M20 in Maidstone, is one of the last two remaining Kentish Ragstone quarries. It has the capability to produce in excess of 1 million tonnes of aggregates per annum, which are processed into more than 70 different construction materials. Gallagher also operates two concrete plants, supplied by our own indigenous aggregates. Additionally, we have a modern recycling facility at Hermitage Quarry which processes waste into a range of recycled aggregates. Inert waste that cannot be recycled is used to fill the void left by quarrying. 

A Van Voorden Apollo 6 primary saw with a 3m diameter blade is installed at Hermitage Quarry. This enables 'sawn six sided' and ‘dimensional slab’ Kentish Ragstone to be supplied to stone masons. Carrying out the primary sawing in the quarry reduces transport costs, greatly reduces waste management at the stone mason’s works and enables the off-cuts to be put into the aggregate process.

Quarrying began at Hermitage Quarry in 1990 when Pat Gallagher (Chairman) was granted planning permission to quarry for Kentish Ragstone on his Hermitage Estate. Over the last two decades Hermitage Quarry has evolved into a highly productive enterprise. To date, some 75 acres reinstated to a combination of agriculture, broadleaved woodland and hedgerows.

Being located in the centre of Kent and near to the major road network, Hermitage Quarry is superbly positioned to supply the industry in one of the UK's highest concentration of construction projects. Over 60 people are employed directly at Hermitage Quarry, with over 100 people employed indirectly through the quarry, from hauliers to suppliers.
