Aggregates
O’Brien Aggregate Marsden are a leading supplier of construction aggregates and agricultural limestone from our quarry on the north east coast located near Whitburn, just to the north of Sunderland. Marsden Quarry has been serving the local region in excess of one hundred years, since around the turn of the 20th century.

The quarry provides a range of primary and recycled construction aggregates that supply markets throughout the North East of England including Northumberland, Tyne and Wear and Co Durham. O’Brien Aggregate Marsden customers include local authorities, civil engineering and construction industry as well as demolition contractors. We work in partnership with each customer to provide expertise, first class service and logistics solutions.

Primary Aggregates
Marsden Quarry provides limestone aggregates to the construction industry in the north-east of England. The quarry can process a range of specific materials depending on end-use requirements – these include granular sub-bases for road and pavement construction, single-size aggregates for drainage and pipe-bedding and also general fills and crusher runs used in various site applications.

• GSB Type 1 - Sub-base suitable for roads & pavements General formation fill
• 6F5 Capping - Capping layer for construction & roads
• Crusher run - Bulk fill material
• 10mm - Pipe bedding, filter media
• 20mm - Pipe bedding, filter media
• 40/50mm - Pipe bedding, filter media
• 75mm - Bulk fill, filter medium
• Block stone including Norwegian granite - Landscaping & access restriction

Recycled Aggregates
A proportion of the inert waste material brought into Marsden Quarry for restoration is capable of being recycled to create recycled aggregate for use in the construction industry. Materials are set aside in a dedicated area where it is then processed. Our recycled aggregates comply with the requirements of the WRAP Quality Protocol.

Recycling of aggregates permits a more diverse and economical use of the quarry, in addition to supplying alternative products for customers. Government and EU policy is to encourage the greatest possible use of recyclable materials as alternatives to primary aggregates, the aims of which our company supports. The above information is for guidance purposes only and does not seek to advise any specific end use due to the varying requirements for individual contracts.

• GSB Type 1 - Sub-base suitable for roads & pavements General formation fill
• 6F5 Capping - Capping layer for construction & roads
• Oversize (75mm) - Bulk fill, filter medium, walling stone

Agricultural Limestone
Marsden Quarry distribute agricultural limestone throughout the UK and export into the northern European agricultural industry. Marsden Quarry produces two types of agricultural limestone as defined by the Fertiliser Regulations 1991:

• Ground Limestone - Consisting largely of calcium carbonate and known as Calcium Lime
• Magnesian Ground Limestone - Consisting largely of calcium carbonate and magnesium carbonate and known as Magnesium Lime

Agricultural limestone is used primarily to maintain soil at the correct acidity (pH). It also improves soil structure, increases plant nutrient uptake and increases bacterial activity in the soil.

Inert Waste Disposal
Marsden Quarry operates a permitted inert waste landfill site as part of the long term Quarry Restoration Scheme approved by South Tyneside Council Mineral Planning Authority, in December 2004.

Inert materials recycled from construction projects across the region are used to refill our quarry and reform the landscape in accordance with the approved contours and landform of the restoration scheme.
