More questions about Quarry Aggregates.
Can I use 20mm gravel as a sub-base?
While 20mm gravel can be used in some light-use areas, it is not ideal as a sub-base. Sub-base layers typically require well-graded materials such as MOT Type 1 or crushed stone that compacts tightly, ensuring stability and strength.
How are Hogan aggregates quality assured?
All Hogan aggregates are sourced from 3 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.
What are the 4 main types of aggregates?
The four main types of aggregates are:
Coarse Aggregates: Larger particles, such as gravel or crushed stone, used for structural strength.
Fine/Sand Aggregates: Smaller particles, like sand, for smooth finishes and filling gaps.
Recycled Aggregates: Materials reused from construction waste, promoting sustainability.
Specialised Aggregates: Tailored for specific purposes, such as decorative or high-strength concrete.
Each has specific uses in building and infrastructure projects. Hogan Group offers a wide range of aggregates to suit your project requirements.
What is quarry aggregate?
