The timeless beauty of Italian Porphyry
Step into a world of enduring elegance with Porphyry Cobblestones. These handpicked natural stone pavers bring a touch of classic charm to your outdoor spaces.
Description
Porphyry Cobbles are available in three formats, each suited to different laying methods and project scales.
Standard cobbles are 100×100mm with a split face finish and 40-60mm thickness - the traditional square format used for full cobblestone fields, driveway aprons and border banding around larger paved areas. Freelength cobbles run 150-400mm long at a consistent 100mm wide, giving a more elongated coursed result that works well as a border alongside crazy paving or freelength tiles. The mesh-mounted option - 100×100×20mm cobbles pre-installed on 320×320mm mesh sheets - is the most practical choice for DIY installation or projects where laying speed matters, with the spacing and alignment already set before the sheet goes down.
All three formats share the same Italian porphyry material: exceptionally dense, split faced on all sides, with the natural colour range of purples, reds, greys and greens that varies across pieces. Thick porphyry cobbles are rated for driveway and vehicular traffic, hold up well in commercial applications, and require no sealing or surface treatment to maintain their appearance over time. Cobbles go hand in hand with Porphyry crazy paving and dedicated steppers - See the full range of Porphyry

FAQ's
What sizes do porphyry cobbles come in?
There are three formats. Standard cobbles are 100 × 100mm and 40-60mm thick. Freelength cobbles run 150-400mm long, 100mm wide and 30-60mm thick. The mesh-mounted option is 100 × 100 × 20mm cobbles on a 320 × 320mm mesh sheet. All are split faced, with the natural mix of purples, reds, greys and greens varying from piece to piece. We also offer custom cutting through our local stonemasonry service, so get in touch if you need something different.
Are porphyry cobbles suitable for driveways?
Yes. Porphyry is exceptionally dense and our cobbles are rated for driveway and vehicular traffic. They also hold up well in commercial applications. The split surface gives good grip underfoot, and the stone stays comfortable in summer because it absorbs little heat.
Do porphyry cobbles need to be sealed?
Sealing isn't required, but we recommend it. Porphyry will hold its appearance without any surface treatment, though a sealer helps protect against staining and makes cleaning easier. Our Installation & Maintenance Guide covers sealing and ongoing care.
How are porphyry cobbles sold?
All porphyry cobbles are sold per m². Measure the area you want to cover and contact our team for a quote, and we'll pack to the quantity your project needs.
What is the mesh-mounted cobble option?
These are 100 × 100 × 20mm porphyry cobbles pre-fixed to a 320 × 320mm mesh sheet, with the spacing and alignment already set. It's the most practical format for DIY projects or jobs where speed matters, and it gives the same look as loose cobbles.
What is the embodied carbon of porphyry cobbles?
Porphyry has a published EPD figure of 27.73 kg CO2e per tonne, measured cradle to gate. The stone is split and cut mechanically with no kiln firing or cement, which keeps its figure well below typical values for concrete, clay and porcelain pavers.
