Why does concrete aggregate quality matter?

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.

Loose aggregate is cheaper per tonne than ready-mix because you are only paying for stone or sand, not cement, admixtures, batching and delivery. Once you add cement, labour, plant and placement, finished concrete is the higher-value, higher-cost product – it is the element providing the structural performance, not just the bulk.

Fine Aggregates
Ideal for smooth finishes in concrete mixes.

Fine aggregates tie your mix together. Clean, consistent sand or fines fill the voids around larger stone, giving you a workable, stable mix that finishes neatly. For slabs, screeds and detailed edges, they help you pour, level and trowel faster, with fewer defects and a better looking surface.

Coarse Aggregates
Perfect for structural applications requiring strength and stability.

Coarse aggregates do the heavy lifting in your mix. Tough gravel and crushed stone form a solid skeleton that carries the load, resists rutting and movement, and stands up to tough site conditions. When you need concrete or sub‑bases that don’t give way, this is where the strength comes from.

Specialised Aggregates
Tailored solutions for unique project specifications.

Specialised aggregates are for jobs where standard stone will not cut it. Whether you need a decorative finish, extra weight, or higher performance, we source and blend to suit. From eye catching gravels to technical mixes, you get material matched to the spec, not a one size fits all load.

The stone is hard and durable, not soft, flaky or easily crushed in handling or service. There is a controlled spread of sizes so the concrete packs densely with minimal gaps.

The aggregates are stable and non-reactive, with low absorption and no components that could cause expansion or surface pop-outs.
