Excellence In Delivery

Hillhouse Quarry Group Ltd is based at Troon in Ayrshire where we operate one of the largest independent whinstone quarries in mainland Scotland.

We are an industry leader, with modern, efficient plant and the capacity to produce in excess of 1million tonnes of quarry products per annum.

The rock extracted in the quarry is a high density basalt with low drying shrinkage properties. This makes it ideal for use as a drystone or as a coated aggregate, and in ready mixed and pre-cast concrete products.


We produce all nominal sized aggregates from whin dust to Type 1 sub-base and can provide rock armour of up to 10t in weight. Our products are used extensively in Ayrshire and have been exported by sea via the nearby ports of Troon and Ayr.

Coated Materials

We operate a total of four coating plants, three of which are located at Troon. The most recent addition was commissioned in early 2015 and together, these provide an unparalleled supply capacity.

Our fourth plant is situated at Cambuslang to the east of Glasgow and became operational in December 2013. It is capable of producing in excess of 200t of coated material per hour and is ideally positioned to serve central Scotland.

We provide the full range of hot rolled asphalts and macadams together with stone mastic asphalts and EME’s.

All coated materials are produced and supplied in accordance with ISO 9001 and the requirements of National Highway Sector Scheme 14.

Readymixed Concrete

Hillhouse operates three ready mixed concrete plants. These are situated at Troon, Kilmarnock and Dalry with uplift / collect facilities being available at the Troon plant. All ready mixed concrete products are manufactured in accordance with BS EN ISO 9001.

We also operate an MCM60 mobile concrete batching plant which can be deployed to site and is capable of producing in excess of 50m3 per hour.
