FAQs
How are Hogan aggregates quality assured?
All Hogan aggregates are sourced from 4 carefully managed sustainable quarries and processed through modern crushing and screening equipment to maintain consistent grading and performance.
Our team tracks quality and gradings continuously, not just at start-up – an ongoing loop of sampling, checking and nudging.
Every load is subject to rigorous quality control, giving contractors confidence in strength, durability and compliance with relevant standards.
How do I know which aggregate is right for my project?
Our team will help you select the most suitable aggregate based on application, load, required drainage and finish, so you get the right performance on site. Whether you need material for sub-base, concrete, asphalt or specialist drainage, we’ll recommend a grade and size that meets current standards and best practice.
Is a 10mm or a 20mm stone better for concrete?
This depends on the type of concrete being produced. Due to its small particle size, 10mm aggregate is better for thin sections, decorative concrete or areas requiring a smoother finish. 20mm aggregate is generally preferred for structural concrete and slabs, as it provides greater strength. We also supply a 14mm allin & 20mm allin designed for concrete.
What aggregate sizes do you supply?
We supply hardstone in 6mm, 10mm, 14mm, 20mm, and 28mm. These cover most standard specifications.
What are the hardest aggregates?
The hardest aggregates are igneous rocks such as granite, basalt, and quartzite. These materials are durable, abrasion-resistant, and have excellent load-bearing capacity. They are ideal for heavy-duty concrete and road construction, as well as high-strength structural applications.
