Rock Products - The Leading Voice of the Aggregate Industries.


By Mark S. Kuhar

Quarrying is a major industry in Northern Ireland. According to the Quarry Products Association Northern Ireland (QPANI), there are approximately 160 quarries and sand pits located there.44-SPCL-Tyron-400

  • The construction industry, which contributes around 10 percent of the province’s gross domestic product, is completely reliant on quarrying.
  • Annual demand for aggregates in Northern Ireland is approximately 24 million tons and the jobs that quarrying supports are often in rural areas where other employment opportunities can be scarce.
  • The quarry products industry employs around 5,600 people in Northern Ireland.

“QPANI currently represents approximately 95 percent of companies involved in the supply of quarry products locally,” said John Shannon of Patrick Bradley Ltd, QPANI chairman.

Northern Ireland is an important source of high-quality aggregate for use in road surfaces across the UK and Europe. This aggregate, because of its hardness, provides increased skid resistance on roads thereby increasing safety.

County Tyrone

County Tyrone (from the Irish “Tír Eoghain,” meaning “land of Eoghan,”) is one of the six counties of Northern Ireland. Adjoined to the southwest shore of Lough Neagh, the county covers an area of 3,155 km², with a population of approximately 166,516, with its county town being Omagh. It is also one of the 32 traditional counties of Ireland, lying within the historical province of Ulster.

According to Library Ireland, the county exhibits some very striking geological features. The red sandstone formation embraces a considerable portion of its southern and eastern parts, while the greatest part of the north and west belongs to the clay-slate formation. In both districts there are considerable exceptions.

The clay-slate is intersected by a vein of micaceous limestone, which first appears in the bed of the river Poe; then passing near Newtown-Stewart and crossing the Munterlowney mountains, it terminates near the village of Dunamanagh, in the northern extremity of the county.

Detached portions of limestone, similar to that of the great central field of Ireland, are to be met with in many parts: white limestone, containing numerous nodules of flint, similar to that of Antrim, is found near Coagh.

County Tyrone is the second largest producer of limestone after County Fermanagh, accounting for about 20 percent of total production in Northern Ireland. Limestones occur in a range of geological ages and environments in County Tyrone, although the most economically important are of the Carboniferous age, according to a Mineral Resource Map of County Tyrone produced in 2012 by the British Geological Survey.

The primary aggregates products extracted in County Tyrone include sand and gravel, basalt, sandstone (including greywacke) and limestone. Most quarries are operated by family-owned businesses, but a number are larger and part of multi-national companies, according to the Geological Society of Northern Ireland.

Important Manufacturing Base

A number of companies are involved in the quarry business in County Tyrone. Since its incorporation in 1992, Dungannon-based Barrack Hill Quarries has played an increasingly important role in the supply of high-quality aggregates and stone to the Irish construction industry; Ardstraw Quarries operates a rock quarry near Victoria Bridge, serving the construction, agricultural and concrete industries, as well as various government agencies; and Devines Sand and Gravel Ltd., situated outside the village of Glenmornan has been providing quality washed sand and gravel for more than 50 years, just to name a few.

It is no surprise that in this strategically important area a number of manufacturing companies have arisen to meet the demand for crushing and screening equipment. There are approximately 90 manufacturing and engineering companies across the county. Although Tyrone has a high percentage of quarries, much of the equipment produced is for export.

Here are several companies featured in this special section.
