How Construction Sand and Gravel Influence Site Performance
Before walls rise or foundations are poured on site across Northern Ireland and ROI, aggregates do the heavy lifting. The quality of the sand decides how cleanly the mortar spreads. The grading of the gravel influences drainage performance and compaction strength. Sub-base layers depend on durable, evenly sized stone that does not shift under load. Each material has a job, and when the quality is off, the entire site feels it.
As a sand and gravel supplier with hands-on experience, we deliver materials that do not slow you down or surprise you mid-pour. Good aggregates should not clump, break down prematurely, create excessive dust, or arrive with moisture levels that compromise workability. Builders notice the difference immediately because the work becomes more manageable and the results more dependable.
Sand & Gravel That Keep Your Site Running Smoothly
Sand and Gravel That Make Every Build Easier
Every sand and gravel supplier will highlight reliability, but we focus on specifics that make day-to-day work easier for the people using our materials.
Finding a sand and gravel company that understands the pressures of a live site should not be complicated. At McGarrity Bros Ltd., we focus on what keeps projects moving: easy scheduling, steady supply, and materials your crew can trust.
Consistent grading
Variations in sand or gravel can throw off mix behaviour and lead to uneven results on site. Our grading stays tight, so every delivery performs exactly as expected.
Clean, ready-to-use aggregates
Clean materials reduce the risk of contamination in concrete and mortar. Our washes, screenings, and checks keep fines at levels suitable for construction work.
Materials that hold their shape under pressure
Good aggregates do more than fill space. They compact evenly, stay stable under load, and form a foundation crews can trust as they build upwards. Ours are produced with this in mind.
Aggregates prepared for modern building requirements
From insulation upgrades to permeable surfacing, today’s construction methods rely on materials that behave consistently under environmental stress. We supply aggregates that support these modern systems without complication.
Choose the Right Aggregates for a Stronger Build
Choosing the Right Sand and Gravel for Your Project
The materials you select shape how smoothly your work progresses and how solid your finished structure will be. Different sand and gravel types suit different tasks, so understanding what each offer can make your planning simpler:
Fine Sand
Ideal for mortar and brickwork, fine sand allows you to create clean joints and smooth finishes. Its texture makes spreading and levelling easier, saving you time and effort on site.
Coarse Sand
When mixing concrete, coarse sand gives you strength and consistency. Its grains bind well with cement and aggregates, helping you achieve stable foundations, floor screeds, and structural mixes.
Washed Sand
If you need sand free of silt or clay, washed sand ensures clean surfaces for paving, drainage beds, or areas where moisture control matters. You can work confidently knowing the material will behave predictably.
Gravel and Aggregates
Available in a range of sizes, gravel supports drainage, foundations, and landscaping. You can select the size and type that suits your application, from compacted base layers to decorative stone finishes.
Specialist Aggregates
For more demanding applications, such as high-performance concrete or energy-efficient builds, specialist aggregates give you control over strength, drainage, and structural performance without compromise.
By selecting the right construction sand or gravel for each task, you make your work more efficient and maintain better control over timing, consistency, and quality on site.
Reliable Delivery That Fits Your Project Schedule

We take care in handling and offloading to prevent contamination, segregation, or loss of material quality. You can focus on your work while knowing that the sand and gravel arriving on site meets your expectations and is ready to use immediately.

Practical Uses Across Modern Construction
Where Our Construction Sand and Gravel Are Used
Construction sand and gravel are versatile, and understanding their uses can help you make the right choice:
Concrete and Mortar
Clean, graded sand and gravel create strong, durable concrete and mortar. Using the right mix supports foundations, walls, and floors that remain solid over time.
Drainage and Groundwork
Gravel and aggregates are essential for managing water around buildings, preventing pooling, and supporting proper drainage on roads, driveways, and gardens.
Landscaping
From decorative gravel for borders and paths to sand for levelling or bedding, our materials help you create visually appealing and practical outdoor spaces.
Driveways and Paving Bases
Gravel forms the ideal base for driveways, paving, and patios. Properly sized aggregates reduce settlement and maintain stability over the years.
Industrial and Commercial Projects
Large-scale construction demands consistent material quality. We supply bulk sand and gravel so that your project can progress without delay.
Each application benefits from materials sourced and supplied with care, reducing the risk of delays or site problems.
