The farm environment is very demanding on concrete. Exposure to silage effluent, slurry and cleaning fluids along with mechanical abrasion from farm vehicles often results in significant damage to concrete. Hanly Quarries Agri Concrete is designed to give a greater long term strength, more durable, requires less repair and is compliant with I.S. EN 206:2013 – Concrete: Specification, performance, production and conformity including the Department of Agriculture, Food & Marine.  

Key benefits and protective characteristics:

• Complies with the Dept. of Agriculture specifications
• Increased resistance to Acids, De-icing salts & Sulphates
• Strong, Durable and long lasting for the agricultural environment
• Made from local materials manufactured to the highest standards
• Available in a range of mixes and strengths to suit all exposures and applications
• Mix design and technical advice available
• Available in a range of colours
