What is Flagstone Paving?
Flagstone paving uses larger, irregular or semi-regular stone pieces rather than uniform brick-sized pavers. The result is a more natural, less regimented appearance — one that suits established gardens, pool surrounds, patios and pathways where you want the paving to feel like a natural extension of the landscape rather than an industrial surface.
Aztec Paving works with flagstones regularly and understands how to select and install them to achieve a result that looks natural but is structurally sound and long-lasting.
LaCotta Flagstones — Our Primary Flagstone Range
The primary flagstone range we work with is LaCotta, a quality South African flagstone product available in a 3-size cobble format. The three sizes — laid together in a random-looking but deliberately planned arrangement — create the organic, natural appearance that makes flagstone paving so appealing. The LaCotta colour range works well with a wide variety of home styles and garden settings.
The three-size format is important. Flagstones of a single size tend to look too uniform and lose the character that makes flagstone appealing. The mixed sizing creates visual interest and a more natural result.
Where Flagstone Works Best
Pool Surrounds
Flagstones are particularly well suited to pool surrounds. The naturally textured surface provides grip when wet, the organic look complements water features and garden planting, and the material handles outdoor conditions well. See our pool paving page for more on pool surround installation requirements.
Patios and Entertainment Areas
A flagstone patio has a character that standard brick paving can't match. For homeowners who want a relaxed, natural-looking outdoor living space rather than a formal grid of uniform bricks, flagstones are often the answer. They look particularly good in gardens with established planting, timber pergolas or lapas, and natural materials throughout.
Garden Pathways
Flagstone garden paths feel like they belong in the garden. Whether laid as a continuous surface or as widely-spaced stepping stones through lawn or planting beds, flagstones integrate with the garden in a way that brick sometimes doesn't.
Laying Flagstones Correctly
Flagstone installation requires more planning and care than standard brick paving. Each piece needs to be positioned and, in many cases, cut or shaped to achieve a good fit with its neighbours. The laying pattern needs to be worked out before installation begins so that the finished result looks intentional rather than haphazard.
Joints between flagstones can be filled with mortar (for a tighter, more formal look), pointing compound, or left slightly open and filled with sand or even planted with creeping ground cover for a very natural appearance.
Flagstone vs Brick — Which is Right for You?
The honest answer depends on your priorities:
- Appearance: Flagstones give a more natural, organic look; brick gives a more structured, formal appearance
- Cost: Flagstones are generally more expensive than standard cement pavers; competitive with quality clay pavers
- Installation: Flagstone takes more time and skill to install correctly
- Maintenance: Both are low-maintenance once properly installed
- Durability: Both are very durable when properly installed
We'll discuss the options with you honestly and help you choose what's right for your specific project and budget. You can also read our paving design article for broader guidance on choosing materials.
Flagstone Paving FAQs
Natural flagstones have a textured surface that provides good grip when wet — considerably better than highly polished stone surfaces. This is one reason they're often recommended for pool surrounds. The specific grip depends on the stone type and finish; we only use materials suitable for outdoor use.
Flagstones can be used for driveways, but it's not their most common application. Standard brick pavers are more practical for driveways because they handle vehicle weight more predictably and are easier to replace if a section is damaged. For driveways, we generally recommend Corobrick clay pavers or suitable cement pavers.
Flagstones can crack under point loads or if the base shifts beneath them. Proper base preparation reduces this risk significantly. If a flagstone does crack, it can generally be removed and replaced without disturbing the surrounding paving, which is one advantage of the material.
Sealing is optional but can enhance the colour and provide additional stain resistance, which is useful around braai areas and pool surrounds. If you choose to seal, use a product designed for outdoor stone. We can advise on sealing options as part of the project.
