Butser Quarry: supplying aggregates to the construction industry

Chalk has been used in the construction industry for decades. It’s versatility, strength, affordability and porous qualities are just some of the things that make it an extremely useful material. The chalk quarried at Butser is the strongest naturally-occuring material in Hampshire and this was something TJ recognised and was one of main reasons their interest in the quarry was piqued.

TJ purchased Butser Quarry in 2017 following a search for sites in Hampshire that would enable them to supply their own aggregates to the construction industry that they’d already built up strong relationships with via the transport and waste disposal arms of the businesses.

After acquiring the Butser site near Petersfield, TJ spent many months getting the site ready for use and quarrying began in 2018. An excavation plan was put in place to ensure safe, efficient and sustainable quarrying for the years to come.

Rock chalk

TJ utilises Butser rock chalk in several forms – as crushed chalk, ‘as dug’ chalk, gabion rock chalk and agglime chalk. The crushed chalk – also referred to as 6F5 rock chalk, is a primary general fill aggregate. It’s most commonly used for capping, laid over terram to raise and level natural ground ready for a Type 1 sub base. This is TJ’s most popular chalk product.

The ‘as dug’ chalk is used as a temporary base or infill for construction projects and works well for these purposes as it is naturally hard. The gabion rock chalk is used within wire baskets as support for soil banks. The agglime part of the chalk is a powder-like material that is spread over agricultural fields to make the ground more fertile.

Recycled aggregates

TJ also produces two recycled aggregates at Butser Quarry – Type 1 iBlend and 6F5 Crushed Concrete. Any rubble, hardcore, concrete, bricks, paving slabs, stone and asphalt that are tipped at the quarry are utilised to make these two aggregates.

Type 1 iBlend is used for ground engineering such as base layers for roads and access areas and is a more cost effective alternative to limestone, which is not only more expensive but also harder to get hold of in the Hampshire and surrounding areas as the nearest limestone quarry is in the Mendips and transportation costs can be high. It is compliant to Type 1, Type 2, 6E, 6R, 6F4, 6I, 6J, 6M, 6N, 6P specifications.

6F5 Crushed Concrete is most commonly used for capping, laid over terrain (such as terram geotextile membranes) to raise and level natural ground ready for a Type 1 sub base layer. It is again, a more sustainable and cost-effective alternative to limestone and is compliant with 6E, 6R, 6F3, 6I, and 6J industry specifications.

Free and easy rubble disposal

All construction companies, contractors and those in the building industry are permitted to drop off unwanted concrete, bricks, paving slabs and stone anytime at our registered waste site near Petersfield during opening hours and as often as needed, free of charge.

We will crush the hardcore and use it to make recycled aggregates that we produce in-house so you know it’s being put to good use, rather than simply going to landfill. Many places charge per bag to dispose of this type of waste, so this could be the ideal solution for many businesses.

Simply bring your hardcore waste along to TJ’s Butser Quarry, which is located on the A3 at Petersfield, GU31 5SP. We’re open 8am – 5pm Monday to Friday. To unload, you simply need to hold a waste carrier’s licence and be wearing a hard hat, hi-vis top and steel toed boots to ensure your safety. Get in touch if you’d like to know more.

Quality, guaranteed

The Environment Agency carries out regular tests on each of our aggregates to ensure the products are fit for purpose and comply with stringent industry standards. We hold test certificates and approvals that illustrate that our aggregates are high calibre and that our production quality is good.
